I foresee this question being asked by a lot of newbies here, and I frankly don't know the answer. It feels like there's an XQuery FAQ to be written and this is Question One, but no one knows the answer yet. :-) Here's the criteria I'd use to judge: 1) The engine must be readily downloadable and available for extended experimental use without a fee. I see having to write to sales@vendor.com for a copy as an impediment to experimentation. A 30-day eval license is perhaps OK but it'd be better to have a license which allowed extended non-deployment experimentation. 2) The engine must be rigorously faithful to the specs. People shouldn't learn bad habits. 3) The engine should be simple to setup and must be usable without a large number of non-XQuery pieces. The more unadorned the XQuery feature, the better for learning. 4) The engine should have good, accurate error reporting. I know how frustrating "Nope, try again" errors can be. 5) The engine need not scale or be high performant. In my own exploration, I've had good luck with Cerisent. However, Cerisent doesn't expose an evaluation download. Ipedo XML Database 3.2 had some problems and so I'm now waiting for the follow-on where I'm told all my problem reports have been fixed. I've heard some good things said recently about Fatdog's XQEngine. Has anyone experimented there? -jh- From per@bothner.com Mon May 12 11:22:58 2003 Received: from tomb.kattare.com (tomb.kattare.com [65.212.180.50]) by jhunter.x-query.com (8.12.8/8.12.4) with ESMTP id h4CIMvST022604 for ; Mon, 12 May 2003 11:22:57 -0700 Received: from mail-out2.apple.com (mail-out2.apple.com [17.254.0.51]) by tomb.kattare.com (8.12.8/8.12.4) with ESMTP id h4CNZiGS012674 for ; Mon, 12 May 2003 16:35:44 -0700 Received: from mailgate2.apple.com (A17-129-100-225.apple.com [17.129.100.225]) by mail-out2.apple.com (8.12.9/8.12.9) with ESMTP id h4CNZlnB019933 for ; Mon, 12 May 2003 16:35:47 -0700 (PDT) Received: from scv3.apple.com (scv3.apple.com) by mailgate2.apple.com (Content Technologies SMTPRS 4.2.1) with ESMTP id for ; Mon, 12 May 2003 16:35:46 -0700 Received: from bothner.com (il0102a-dhcp62.apple.com [17.201.27.190]) by scv3.apple.com (8.12.9/8.12.9) with ESMTP id h4CNZkRM001169 for ; Mon, 12 May 2003 16:35:46 -0700 (PDT) Message-ID: <3EC0300F.9040306@bothner.com> Date: Mon, 12 May 2003 16:36:47 -0700 From: Per Bothner User-Agent: Mozilla/5.0 (Macintosh; U; PPC Mac OS X Mach-O; en-US; rv:1.4b) Gecko/20030507 X-Accept-Language: en-us, en MIME-Version: 1.0 To: talk@x-query.com Content-Type: text/plain; charset=us-ascii; format=flowed Content-Transfer-Encoding: 7bit Subject: [xquery-talk] Re: Best engine for learning?

I haven't tried other implementations, but here are some reasons to consider my own Qexo engine. Of course I'm biased, but at least when it comes to Qexo I know of what I speak! > 1) The engine must be readily downloadable and available for extended > experimental use without a fee. Qexo is Free Software (Open-Source if you prefer), available without charge in both binary and source form (with a public CVS repository). > 2) The engine must be rigorously faithful to the specs. People > shouldn't learn bad habits. Huh? The most recent specs are about a week old. Even those have plenty of inconsistencies and unclear issues. Are there any implementations are are "regorously faithful to the specs"? Even the Novembver '02 version? What about static typing and schema import? Qexo may be less faithful/complete than some implementations, and more than others, but it is coming along well. I just implemented the new comment syntax, plus some other changes, including the new KindType syntax. One peeve: On the x-query.com homepage, only Qexo is listed as a "partial implementation", with the misleading implication that the other implementations are complete. Qexo is complete enough to do useful work with, as illustrated by the pages linked to from Qexo home page (http://www.gnu.org/software/qexo/). I admit there are big holes; no schema support, very limited static typing (though the hooks are there), no sorting, no duplicate removal in path expressions, many functions are not yet implemented, builtin functions are in the wrong namespace. But it has FLWR expressions, functions, typeswitch, some typing support, element constructors (both kinds), namespace support (except for namespace nodes), an efficient XML parser and DOM representation, decent error handling, a Java interface, lots of functions, and can be used in various modes, including command-line and servlets. > 3) The engine should be simple to setup and must be usable without a > large number of non-XQuery pieces. All you need is a Java VM and the Kawa .jar file. The kawa-1.7beta1 is usable, but kawa-1.7beta2 (should be out this weekend) will have a number of improvents, including the ones mentioned above. > 4) The engine should have good, accurate error reporting. I know how > frustrating "Nope, try again" errors can be. It's fairly decent. See the second half of this (draft) article at http://www.gnu.org/software/qexo/simple-xquery-webapp.html . (The article is servlet-centric, but the error handling is general. I made some recent improvements to syntactic error recovery; and the article is based on the CVS or forthcoming 1.7beta2 version of Qexo.) This article http://www.gnu.org/software/qexo/Running.html is useful how-to on using Qexo, and it illustrates error messages - though it has not been updated for the new comment syntax. > 5) The engine need not scale or be high performant. Since Qexo uses a compiler, it has decent performance, and hooks for further optimization. -- --Per Bothner per@bothner.com http://per.bothner.com/ From jhunter@acm.org Tue May 13 08:59:35 2003 Received: from tomb.kattare.com (tomb.kattare.com [65.212.180.50]) by jhunter.x-query.com (8.12.8/8.12.4) with ESMTP id h4DFxZST023828 for ; Tue, 13 May 2003 08:59:35 -0700 Received: from snowball.huntershots.com ([65.122.201.44]) by tomb.kattare.com (8.12.8/8.12.4) with ESMTP id h4DLYKFk003358 for ; Tue, 13 May 2003 14:34:21 -0700 Received: from acm.org (snowball [192.168.1.4]) by snowball.huntershots.com (8.12.9/8.12.2) with ESMTP id h4DLZUFU000687 for ; Tue, 13 May 2003 14:35:30 -0700 (PDT) Message-ID: <3EC16446.22D01021@acm.org> Date: Tue, 13 May 2003 14:31:50 -0700 From: Jason Hunter X-Mailer: Mozilla 4.75 [en] (Windows NT 5.0; U) X-Accept-Language: en MIME-Version: 1.0 To: talk@x-query.com Subject: Re: [xquery-talk] Re: Best engine for learning?

I actually like any engine that conforms well to a particular date, rather than being a mix with some-April, some-November, and some-May for example. It gets old trying everything three different ways. :-) > Even those have > plenty of inconsistencies and unclear issues. Are there any > implementations are are "regorously faithful to the specs"? Even > the Novembver '02 version? Good question. I'd hope to point newbies at an engine that was as faithful as possible, with the ideal being one where the developers say, "It's not perfect, but we can't do anything to be more compliant til the next draft rev clears some things up." > One peeve: On the x-query.com homepage, only Qexo is listed as a > "partial implementation", with the misleading implication that the > other implementations are complete.

I knew I was getting myself into hot water by expressing any opinions about engines. The list of items TBD on Qexo justifies its "partial" status IMO. Whether the others can or should be inferred to be "complete" is debatable, but their "pending" lists seem significantly shorter. I don't mean to offend anyone, but I do want to provide a little editorial guidance for visitors so they know what to expect. -jh- From jhunter@servlets.com Tue May 13 09:17:28 2003 Received: from snowball.huntershots.com ([65.122.201.44]) by jhunter.x-query.com (8.12.8/8.12.4) with ESMTP id h4DGHSST023848 for ; Tue, 13 May 2003 09:17:28 -0700 Received: from servlets.com (snowball [192.168.1.4]) by snowball.huntershots.com (8.12.9/8.12.2) with ESMTP id h4DLrWFU000694 for ; Tue, 13 May 2003 14:53:33 -0700 (PDT) Message-ID: <3EC16880.50800E10@servlets.com> Date: Tue, 13 May 2003 14:49:52 -0700 From: Jason Hunter X-Mailer: Mozilla 4.75 [en] (Windows NT 5.0; U) X-Accept-Language: en MIME-Version: 1.0 To: "talk@x-query.com" Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit Subject: [xquery-talk] Brainteaser X-BeenThere: talk@x-query.com X-Mailman-Version: 2.1.2 Precedence: list List-Id: XQuery discussion List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Tue, 13 May 2003 16:17:28 -0000 Here's a brainteaser XQuery problem, borrowed from a co-worker's real problem from this afternoon.

Assume an XML file "teaser.xml": One 2003-05-12T18:07:35Z Two 2003-05-12T18:09:01Z The following query contains three enclosed expressions, only one of which actually works as intended. The comments in the query describe the situation. Who can figure out the reason? define function get-root() as element { document("teaser.xml")/root }
This correctly prints the original document { get-root() }

This should print the original document, but doesn't { document("teaser.xml")/root }

This should print the names, but doesn't { get-root()/record/name }

That's how I actually found it initially, by simplifying til things worked and expanding back out. Which raises an interesting question: What's the best way people have found to *debug* queries?

The May specification includes a trace(VALUE, STRING) function that is at least partly intended for debugging. The latest CVS version of Qexo include the trace functions.

Per the F&O 4.1 example: -- Consider a situation in which a user wants to investigate the actual value passed to a function. Assume that in a particular execution, $v is an xs:decimal with value 124.84. Writing fn:trace($v, 'the value of $v is:') will put the strings "124.84" and "the value of $v is" in the trace data set in implementation defined order. -- So the output will either be English "the value of $v is 124.84" or Yoda "124.84 the value of $v is". :-) -jh- From per@bothner.com Mon May 19 06:50:26 2003 Received: from tomb.kattare.com (tomb.kattare.com [65.212.180.50]) by jhunter.x-query.com (8.12.8/8.12.4) with ESMTP id h4JDoQST030036 for ; Mon, 19 May 2003 06:50:26 -0700 Received: from mail-out2.apple.com (mail-out2.apple.com [17.254.0.51]) by tomb.kattare.com (8.12.8/8.12.4) with ESMTP id h4JKnt7B003935 for ; Mon, 19 May 2003 13:49:55 -0700 Received: from mailgate1.apple.com (A17-128-100-225.apple.com [17.128.100.225]) by mail-out2.apple.com (8.12.9/8.12.9) with ESMTP id h4JKntBx013989 for ; Mon, 19 May 2003 13:49:57 -0700 (PDT) Received: from scv3.apple.com (scv3.apple.com) by mailgate1.apple.com (Content Technologies SMTPRS 4.2.1) with ESMTP id ; Mon, 19 May 2003 13:49:41 -0700 Received: from bothner.com (il0102a-dhcp124.apple.com [17.201.27.252]) by scv3.apple.com (8.12.9/8.12.9) with ESMTP id h4JKnsI2020272; Mon, 19 May 2003 13:49:55 -0700 (PDT) Message-ID: <3EC943B8.8010805@bothner.com> Date: Mon, 19 May 2003 13:51:04 -0700 From: Per Bothner User-Agent: Mozilla/5.0 (Macintosh; U; PPC Mac OS X Mach-O; en-US; rv:1.4b) Gecko/20030507 X-Accept-Language: en-us, en MIME-Version: 1.0 To: Jason Hunter Subject: Re: [xquery-talk] Re: Debugging References: <41D11F414A26E942912B7E7696DC8E226C37AA@JAKARTA.xhive.archipel> <3EC200F1.4BEABC2F@servlets.com> <3EC57850.70605@bothner.com> <3EC93789.19C73199@servlets.com> In-Reply-To: <3EC93789.19C73199@servlets.com> Content-Type: text/plain; charset=us-ascii; format=flowed Content-Transfer-Encoding: 7bit Cc: talk@x-query.com X-BeenThere: talk@x-query.com X-Mailman-Version: 2.1.2 Precedence: list List-Id: XQuery discussion List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Mon, 19 May 2003 13:50:26 -0000 Jason Hunter wrote: > It does seem odd the order of the two params [to trace] is left > "implementation defined".

Or: QXuery trace output value: 124.84 label: "the value of $v is" I think the example *suggests* that the label will be written first, bt you cannot count on it. However, I suspect the "implementation defined order" is actually talking about the different invocations of trace. -- --Per Bothner per@bothner.com http://per.bothner.com/ From Sullivan.Sean@menlolog.com Wed May 21 03:40:58 2003 Received: from ljcqs053.cnf.com (mailhost2.cnf.com [63.230.177.24]) by jhunter.x-query.com (8.12.8/8.12.4) with ESMTP id h4LAewST031942 for ; Wed, 21 May 2003 03:40:58 -0700 Received: from cnfqs057.cnf.prod.cnf.com (localhost [127.0.0.1]) by ljcqs053.cnf.com (Postfix) with ESMTP id 51EEE7AC for ; Wed, 21 May 2003 11:05:19 -0700 (PDT) Received: by cnfqs057.cnf.prod.cnf.com with Internet Mail Service (5.5.2653.19) id ; Wed, 21 May 2003 11:05:18 -0700 Message-ID: From: "Sullivan, Sean C - MWT" To: "'talk@x-query.com'" Date: Wed, 21 May 2003 11:05:16 -0700 MIME-Version: 1.0 X-Mailer: Internet Mail Service (5.5.2653.19) Content-Type: text/plain Subject: [xquery-talk] XQuery page on the JINX wiki X-BeenThere: talk@x-query.com X-Mailman-Version: 2.1.2 Precedence: list List-Id: XQuery discussion List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Wed, 21 May 2003 10:40:58 -0000 The JINX wiki has an XQuery page: http://jinx.swiki.net/416 Feel free to update the page with additional resources. -Sean From Sullivan.Sean@menlolog.com Wed May 21 07:42:00 2003 Received: from tomb.kattare.com (tomb.kattare.com [65.212.180.50]) by jhunter.x-query.com (8.12.8/8.12.4) with ESMTP id h4LEfxST032167 for ; Wed, 21 May 2003 07:42:00 -0700 Received: from ljcqs053.cnf.com (mailhost2.cnf.com [63.230.177.24]) by tomb.kattare.com (8.12.8/8.12.4) with ESMTP id h4LMAuLl031044 for ; Wed, 21 May 2003 15:10:56 -0700 Received: from cnfqs057.cnf.prod.cnf.com (localhost [127.0.0.1]) by ljcqs053.cnf.com (Postfix) with ESMTP id CBC7A86A for ; Wed, 21 May 2003 15:10:53 -0700 (PDT) Received: by cnfqs057.cnf.prod.cnf.com with Internet Mail Service (5.5.2653.19) id ; Wed, 21 May 2003 15:10:53 -0700 Message-ID: From: "Sullivan, Sean C - MWT" To: "'talk@x-query.com'" Date: Wed, 21 May 2003 15:10:48 -0700 MIME-Version: 1.0 X-Mailer: Internet Mail Service (5.5.2653.19) Content-Type: multipart/alternative; boundary="----_=_NextPart_001_01C31FE5.D5256C64" Subject: [xquery-talk] XQuery, BEA Liquid Data, Enosys Software X-BeenThere: talk@x-query.com X-Mailman-Version: 2.1.2 Precedence: list List-Id: XQuery discussion List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Wed, 21 May 2003 14:42:01 -0000 This message is in MIME format.

June 12, 2003 San Francisco, CA USA Heterogeneous XML-Based Data Integration Using XQuery, JavaTM 2 Platform, Enterprise Edition (J2EETM) and Database Technologies http://servlet.java.sun.com/javaone/sf2003/conf/sessions/display-1212.en.jsp Abstract Data Integration is an important business problem that companies frequently need to solve. It can provide an up-to-the-minute complete view of the whole enterprise by aggregating information from different sources of data scattered within and outside a company, such as multiple databases, legacy sources, Web services, and so on. Given the diverse characteristics of heterogeneous data sources in real life, data integration is not a trivial task. Fortunately, XML and XQuery are relevant standards that simplify this problem domain greatly. The XQuery language can be used to express an aggregated XML-based view over the various data sources. In this session, we discuss in detail the roles of XML and XQuery for data integration using Java TM technology and databases and cover both "push" and "pull" models of data access and parameterized data sources. Heterogeneous data sources in the JavaTM 2 Platform, Enterprise Edition (J2EETM) world do not directly fit into the XQuery engine, and Java technology-based adaptors are needed to feed in the data. We discuss some common types of adaptors and issues in designing them. We also describe optional but useful capabilities that could be associated with data sources, such as caching, security and object mapping services, and how aggregated views could be published and used as programmatic components. We go through a step-by-step example to illustrate how these technologies can be used for building a data integration solution quickly and efficiently. In this session, you learn how to use J2EE and database technologies together with XQuery to achieve heterogeneous XML-based data integration.

This year's is more about the implementation rather than the languages, as I use examples from multiple Kawa languages, not just XQuery. -- --Per Bothner per@bothner.com http://per.bothner.com/ From per@bothner.com Wed May 21 12:39:21 2003 Received: from tomb.kattare.com (tomb.kattare.com [65.212.180.50]) by jhunter.x-query.com (8.12.8/8.12.4) with ESMTP id h4LJdKST032438 for ; Wed, 21 May 2003 12:39:21 -0700 Received: from mta5.snfc21.pbi.net (mta5.snfc21.pbi.net [206.13.28.241]) by tomb.kattare.com (8.12.8/8.12.4) with ESMTP id h4M3Awvh011230 for ; Wed, 21 May 2003 20:10:58 -0700 Received: from bothner.com ([216.102.199.253]) by mta5.snfc21.pbi.net (iPlanet Messaging Server 5.1 HotFix 1.6 (built Oct 18 2002)) with ESMTP id <0HF9003NOQ6EMZ@mta5.snfc21.pbi.net> for talk@x-query.com; Wed, 21 May 2003 20:11:02 -0700 (PDT) Date: Wed, 21 May 2003 20:12:14 -0700 From: Per Bothner Subject: Re: [xquery-talk] XQuery API's In-reply-to: To: "Sullivan, Sean C - MWT" Message-id: <3ECC400E.2050009@bothner.com> MIME-version: 1.0 Content-type: text/plain; format=flowed; charset=us-ascii Content-transfer-encoding: 7bit X-Accept-Language: en-us, en User-Agent: Mozilla/5.0 (Macintosh; U; PPC Mac OS X Mach-O; en-US; rv:1.4b) Gecko/20030507 References: Cc: "'talk@x-query.com'" X-BeenThere: talk@x-query.com X-Mailman-Version: 2.1.2 Precedence: list List-Id: XQuery discussion List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Wed, 21 May 2003 19:39:21 -0000 See http://www.gnu.org/software/qexo/Running.html for some examples of Qexo's APIs.

It forces all "nodes" to implement XMLNodes, or to wrap them. Why not just use the XQueryResultSet as the interface between the generic API and the implementation?

A useful API would be that of a "pull parser", or a tree iterator. You'd ask the iterator what's next, and the client can extract it using various methods, skip it, traversing recursively, or send the next object to a "push" SAX-like consumer. The Qexo implementation provides something like that, but it's not as smooth or complete as it should be. -- --Per Bothner per@bothner.com http://per.bothner.com/ From Sullivan.Sean@menlolog.com Thu May 22 08:03:21 2003 Received: from tomb.kattare.com (tomb.kattare.com [65.212.180.50]) by jhunter.x-query.com (8.12.8/8.12.4) with ESMTP id h4MF3LST000874 for ; Thu, 22 May 2003 08:03:21 -0700 Received: from ljcqs053.cnf.com (mailhost2.cnf.com [63.230.177.24]) by tomb.kattare.com (8.12.8/8.12.4) with ESMTP id h4MMmgnc028360 for ; Thu, 22 May 2003 15:48:42 -0700 Received: from cnfqs057.cnf.prod.cnf.com (localhost [127.0.0.1]) by ljcqs053.cnf.com (Postfix) with ESMTP id E63A3E14 for ; Thu, 22 May 2003 15:46:46 -0700 (PDT) Received: by cnfqs057.cnf.prod.cnf.com with Internet Mail Service (5.5.2653.19) id ; Thu, 22 May 2003 15:46:46 -0700 Message-ID: From: "Sullivan, Sean C - MWT" To: "'talk@x-query.com'" Date: Thu, 22 May 2003 15:46:44 -0700 MIME-Version: 1.0 X-Mailer: Internet Mail Service (5.5.2653.19) Content-Type: text/plain Subject: [xquery-talk] IBM DB2 Information Integrator, J2EE X-BeenThere: talk@x-query.com X-Mailman-Version: 2.1.2 Precedence: list List-Id: XQuery discussion List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Thu, 22 May 2003 15:03:22 -0000 Although this is not XQuery technology, it appears to serve a similar purpose.

IPSI-XQ is an implementation of the upcoming W3C XQuery standard for an XML query language. It is implemented as faithfully as possible along the current W3C Working Drafts. It is available for free for non-commercial usage. It comes along with several user interfaces - a graphical, a command line and web interface - and it has a wide JAVA API to integrate it into other applications. The new version 1.3.0 is based on the latest working drafts of May 2nd. In this version most of the functions and operators have been implemented. Additionally the Java API was widely enhanced. Version 1.3.0 has the following modifications to 1.2.2: - The syntax and semantics is modified to reflect the Working Drafts from 2003-05-02. - Most of the functions and operators are implemented, including support for date, time and durations. - Improved performance. - Global variables are supported. - Strongly enhanced API, supports plug-in of own data model implementations, definition of external functions, definition of external variables, more control when calling IPSI-XQ and exposition of XQuery AST as framework for own XQuery applications. - Improved output window for the GUI. Have a look at our web site (http://ipsi.fhg.de/oasys/projects/ipsi-xq/index_e.html) and download the latest version. Any feedback is extremely welcome!

All other implementations are closed, out of date or tied to expensive commercial native XML DBs."

What I'd most like to see is an XQuery engine that doesn't try to hard to be an NXD or web application server. All I really want is a command line tool: % xqueryengine [queryfile] [xmlfile] With the result dumping out to stdout.

Is > there some other means of accomplishing this that I'm not aware of? The XQuery WG has had this debate a number of times, and although there are many people who would like to offer the full set of axes, we haven't (so far) been able to sway the argument. But in the next draft, XQuery processors will be *allowed* to offer all the axes, though not "*required* to do so. So we-re making progress... I find it difficult to state the arguments against offering all the axes, since I find them unconvincing. The most common argument is that it's difficult to optimize them - but then, it's even harder to optimize the workaround that the user is forced to write if the axes aren't available. Another argument is that they aren't needed - this seems to come from people who have only ever encountered neat tabular XML that maps directly to relational structures. There is a simple workaround for following-sibling::x, you can write let $current := . return ../child::x[. >> $current] and similarly for preceding-sibling.

One axis that many people find very useful is "ancestor", especially when dealing with XML with nested structures, e.g. {-- Find the para in section, subsection, etc. -- Return the book title. --} let $para := .... return $para/ancestor::book/title -- Alex Cheng From schochler3@yahoo.com Fri Jul 11 04:31:51 2003 Received: from web40111.mail.yahoo.com (web40111.mail.yahoo.com [66.218.78.45]) by jhunter.x-query.com (8.12.8/8.12.4) with SMTP id h6BBVpi6021328 for ; Fri, 11 Jul 2003 04:31:51 -0700 Message-ID: <20030711114348.30724.qmail@web40111.mail.yahoo.com> Received: from [198.185.18.207] by web40111.mail.yahoo.com via HTTP; Fri, 11 Jul 2003 04:43:48 PDT Date: Fri, 11 Jul 2003 04:43:48 -0700 (PDT) From: rick schochler Subject: RE: [xquery-talk] following-sibling and preceding-sibling To: Alex Cheng , talk@x-query.com In-Reply-To: MIME-Version: 1.0 Content-Type: text/plain; charset=us-ascii Cc: X-BeenThere: talk@x-query.com X-Mailman-Version: 2.1.2 Precedence: list List-Id: XQuery discussion List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Fri, 11 Jul 2003 11:31:51 -0000 Sure. Still, it seems that it would be speedier (especially when talking about querying large amounts of data) for an xquery engine to look left or right, rather than having to go back up a node tree and look down again. --- Alex Cheng wrote: > > > The XQuery WG has had this debate a number of > times, and although > there > > are many people who would like to offer the full > set of axes, we > haven't > > (so far) been able to sway the argument.

The absence of preceding and following sibling axes strikes me as rather odd, if for no other reason than the fact that xquery is being developed side by side with xpath 2.0 (and thus, I'd assume that it would fully implement xpath functionality). -----Original Message----- From: Michael Kay [mailto:mhk@mhk.me.uk] Sent: Thursday, July 10, 2003 6:48 AM To: 'Schochler, Rick (LNG-DAY)'; talk@x-query.com Subject: RE: [xquery-talk] following-sibling and preceding-sibling > what is the logic/rational > behind the apparent restriction of left/right navigation? Is > there some other means of accomplishing this that I'm not aware of? The XQuery WG has had this debate a number of times, and although there are many people who would like to offer the full set of axes, we haven't (so far) been able to sway the argument. But in the next draft, XQuery processors will be *allowed* to offer all the axes, though not "*required* to do so. So we-re making progress... I find it difficult to state the arguments against offering all the axes, since I find them unconvincing. The most common argument is that it's difficult to optimize them - but then, it's even harder to optimize the workaround that the user is forced to write if the axes aren't available. Another argument is that they aren't needed - this seems to come from people who have only ever encountered neat tabular XML that maps directly to relational structures. There is a simple workaround for following-sibling::x, you can write let $current := . return ../child::x[. >> $current] and similarly for preceding-sibling.
