Subject: [xquery-talk] Using XQuery to prerender html
Message-ID: <BAY114-W22C950FA0773F91A4399B6F8750@phx.gbl>


Hi,

I am totally new to XQuery and I would like to know if it is suitable to use XQuery to transform html files into jQuery Treeview format.


Basically, what I would like to to is transform this:

<li>
  <img src="../images/speaker-grey.gif"/>
  <font color="#7f7f7f">
    <b>Root</b>
  </font>
  <ul>
    <li>
      <span class="folder">Order</span>
      <ul>
        <li>
          <span class="file">id = 1234</span>
        </li>
        <li>
          <span class="file">type = order.cancel</span>
        </li>
        <li>
          <span class="folder">Parameter</span>
          <ul>
            <li>
              <span class="file">id = 5678</span>
            </li>
          </ul>
        </li>
        <li>
          <span class="folder">Item</span>
          <ul>
            <li>
              <span class="file">id = 910</span>
            </li>
            <li>
              <span class="file">type = access</span>
            </li>
          </ul>
        </li>
      </ul>
    </li>
  </ul>
</li>



.. into this:

<ul class="filetree treeview">
  <li class="expandable lastExpandable">
    <div class="hitarea expandable-hitarea lastExpandable-hitarea"/>
    <img src="../images/speaker-grey.gif"/>
    <font color="#7f7f7f">
      <b>Root</b>
    </font>
    <ul style="display: none;">
      <li class="collapsable lastCollapsable">
        <div class="hitarea collapsable-hitarea lastCollapsable-hitarea"/>
        <span class="folder">Order</span>
        <ul>
          <li>
            <span class="file">id = 1234</span>
          </li>
          <li>
            <span class="file">type = order.cancel</span>
          </li>
          <li class="collapsable">
            <div class="hitarea collapsable-hitarea"/>
            <span class="folder">Parameter</span>
            <ul>
              <li class="last">
                <span class="file">id = 5678</span>
              </li>
            </ul>
          </li>
          <li class="collapsable lastCollapsable">
            <div class="hitarea collapsable-hitarea lastCollapsable-hitarea"/>
            <span class="folder">Item</span>
            <ul>
              <li>
                <span class="file">id = 910</span>
              </li>
              <li class="last">
                <span class="file">type = access</span>
              </li>
            </ul>
          </li>
        </ul>
      </li>
    </ul>
  </li>
</ul>


This the structure of this jQuery Treeview:

Root
  Order
    id = 1234
    type = order.cancel
    Parameter
      id = 5678
      Item
        id = 910
        type = access


Any ideas how to do this are highly appreciated!

Subject: [xquery-talk] Problem with "let" statements in an xquery function
Message-ID: <c05fae8d0808121445l240c286bx5a7aff18a659f281@mail.gmail.com>

Hi,

I'm puzzled about this function I'm working on:

declare updating function
       do_stuff
(
       $a as element(),
       $b as xs:string
)
{
       let $c := $a//some_element[.=$b]/..[another_elem='foo']
       let $d := $a//anoher/element

       return
       if( exists($c) )
       then
               replace value of node $c/xxx with $d
       else
               ()
};

The problem is, those "let" statements aren't working... if I check the
value of $c or $d they're null. And the xpath expression I'm using is valid.
Based on the W3 specs I understand those "let" declarations are valid:

http://www.w3.org/TR/2008/CR-xquery-update-10-20080801/#doc-xquery-FunctionDecl

What am I missing? Should I assign those variables in some other way? I
tried using "declare variable" instead but that didn't work either.
Thanks for any comments, I think I could use an extra pair of eyes. :-)

$a//some_element[.=$b]/..[another_elem='foo']

That line is almost certainly the problem... what are you trying to do there?

  I don't know if it is the problem, but at least this is not how I
would write what it says.  I would rather use the equivalent (except
for one corner case):

    $a//*[some_element = $b][another_elem = 'foo']

  But without input sample, we don't know if those are correct or not.

Message-ID: <43b5c44e0808210205mb49b29ckf79e45049ab51f68@mail.gmail.com>

Hi,

PECL, the official repository for PHP extensions contains now a
language binding for Zorba XQuery engine:
http://www.pecl.php.net/package/Zorba.
PHP always had a great support for XML and we're happy that it
supports now XQuery.
You can find more information about this release in the following blog
entry: http://www.zorba-xquery.com/index.php/24/.

Best regards,

William

Message-ID: <EC7423A1DA34E340978D0CC83F9120F00531F129@nets13ja.ww300.siemens.net>

Hi,

I'm very new to Xquery and don't know much more than what I've read in a
tutorial. Now I have trouble with a query where I need an if-statement
inside a FLWOR-expression. The following minimal example shows the
problem:

    for $item in (1 to 5)
        if ($item < 3) then 
            let $var := 'abc'
        else
            let $var := 'def'
        return 
            <p>Text {$var}</p>

The 'if' doesn't seem to be permitted after the for, I get an error
message
  "Parse error: element name containing whitespace: unexpected token:
if"
What can I do to solve this?

Thanks, Georg

XQuery is a functional, expression-oriented language. What you want to
write is

  let $var := if ($item < 3) then 'abc' else 'def' 
  return <p>Text {$var}</p>

Observe how the `if ...' does not imply a certain control flow. Rather,
the entire clause is an expression that evaluates to either 'abc' or
'def'.

Message-ID: <d2cb7acf0808220141i5d7f9cb9r63238ade4b9aaf2f@mail.gmail.com>

Hi All,
I am facing some issue in XQuery with Marklogic database.

In the below example,

<books>
  <book >
    <information>
      <name> HF </name>
      <pages>45</pages>
    </information>
  </book>
  <book>
    <information>
      <name>Core</name>
      <pages>67</pages>
   </information>
  </book>
</books>

When i try,
data(doc("book.xml")/books/book/information))

the output in StylusStudio is
HF 45 Core 67868

which is something i expected. But when i try the same in Marklogic database
I get it in

HF45Core67868

how can i modify my query to get the output like

HF 45 Core 67868

Thanks in advance,
Bharath

To combine items in a sequence with a separator you can use
string-join() eg string-join($seq, ' ')

However, you can't be telling us the full story because neither of
your output's could be made from that input with that query...

It's probably just a case of whitespace stripping, but it's hard to
say anything more than that.

Thank you, that clearifies a lot. But now I want to go a step further.
In my original problem I don't have only one variable $var to set in
each of the if-branches, but several ones. So my original (and of course
wrong) approach was

         if ($item < 3) then 
             let $var1 := 'abc'
             let $var2 := ...
             ...
         else
             let $var1 := 'def'
             let $var2 := ...
             ...
         return 
             <p>Text {$var1} text {$var2} </p>

I don't see how to map this to the correct syntax in a straightforward
way.
Thanks again, Georg

It's because annoyingly the list is setup to be reply-to-sender
instead of reply-to-list.... (it's not Outlook's fault)

So many replies must be lost and not archived because of this -
hopefully the list admin will change it.

Nope, it's intentional.  Without the reply-to header you get some  
emails accidentally mailed privately and when it happens people post  
them publicly.  No big harm, easy to fix.  With the header you get  
some emails that were meant for private consumption that get  
accidentally mailed publicly.  Can cause harm, impossible to rectify.

hmmm so the reason everyone has go to through the hassle of first
realising they've not replied to the list and then sending it again
(not to mention the loss to the archives), is all because some people
might send something publicly that was meant to be private??

Surely not...

Other lists (such as the xsl-list) are reply-to-list and that's doing
just fine, no harm so far (in the 8 or so years I've been on there.

Georg,

Just extend the logic:

   let $var1 := if ($item < 3) then 'abc' else 'def'
   let $var2 := if ($item < 3) then 'lmn' else 'opq'
   return <p>Text {$var1} ... {$var2}</p>

or further:

   let $lowitem := ($item < 3)
   let $var1 := if ($lowitem) then 'abc' else 'def'
   let $var2 := if ($lowitem) then 'lmn' else 'opq'
   [ ... etc. ...]
   return <p>Text {$var1} ... {$var2}</p>

Alternatively, use sequences, and index into them:

   let $var := if ($item < 3) then ('abc','lmn')
                              else ('def','opq')
   return <p>Text {$var[1]} ... {$var[2]}</p>

Cheers,
Wendell

Heh. As it happens, xsl-list has from time to time seen messages not 
intended for the list. On more than one occasion (though not 
frequently), the list owner (who works down the hall from me) has 
even received frantic messages from embarrassed or irate users 
requesting that their publicly-posted messages be retracted. As if.

(Admittedly, these are not always because they've mistakenly replied 
on-list when they thought they were off-list. Once, IIRC, it was 
because the person didn't want to be archived asking a question, on 
the theory that future prospective employers might discover it. 
Apparently, such are the perils of list ownership, which seems to be 
a job somewhere between a kindergarten teacher and a janitor.)

So, I'm afraid there's no right answer, just strong feelings, and 
Jason has to be allowed to do it the way he wants.

FWIW, personally I agree with you. People learn to work with 
reply-to-list, and then it's a considerable convenience.

Cheers,
Wendell

A mailing list is singular. I am with Andrew... I am sure the folk who
got your response once through the list and then addressed to them
personally appreciate the duplicate.

It's a religious issue.  Minds never change.  :)

In case you're curious, the scripture to my religion is documented at http://www.unicom.com/pw/reply-to-harmful.html 
.  Coincidentally it's the top Google hit for "reply-to".

Hang on, let me cut the Cc: to the list and paste it over the To:

OK, done. 

I don't buy the argument, but you da man. A person did not send me the
message, the list did.

Anyway, I will check with the Flying Spaghetti Monster and get back to
you.

The "Principle of Least Work" and "Principle of Least Suprise" are the
opposite of the real world there...  They're basing it on the
"Principle of You Want to Reply to the Sender" so it's effort to reply
to the list - but I don't want to reply to the sender, and it's
annoying when people reply directly to me - do I then reply to the
list or directly to them?  If I reply to the list and quote their
direct reply, should I get permission first?  If I've got 3 direct
replies all saying the same thing, should I reply to each, or ignore
them?

Anyway....

Subject: [xquery-talk] xpath/xquery to eleminate certain nodes
Message-ID: <46377.80.85.196.22.1219744464.squirrel@www.wms-network.de>

Hi,

I am fighting with a xpath/xquery expression to select the whole xml
document except of certain nodes that I want to remove. The general
structure of the document should be preserved.

With my approaches I either select too much or too less and my research @
google & co. did not bring me any further :-(

The document structure is a bit tricky (arbitrarily nested categories) -
imagine the following document:
<sites>
  <site>
    <categories>
      <category name="root">
        <categories>
          <category name="category_1">
            <some>
              <further>
                <nested>
                  <info info_id="1">Important Information</info>
                </nested>
              </further>
            </some>
          </category>
          <category name="category_2">
            <some>
              <further>
                <nested>
                  <info info_id="2">Less Important Information</info>
                </nested>
              </further>
            </some>
          </category>
        </categories>
      </category>
      <category name="hidden">
        <categories>
          <category name="dont_need_it">
            <some>
              <further>
                <nested>
                  <info info_id="3">Unimportant Information</info>
                </nested>
              </further>
            </some>
          </category>
          <category name="dont_need_it_too">
            <some>
              <further>
                <nested>
                  <info info_id="4">Even More Unimportant Information</info>
                </nested>
              </further>
            </some>
          </category>
        </categories>
      </category>
    </categories>
  </site>
</sites>

What I want would be:
<sites>
  <site>
    <categories>
      <category name="root">
        <categories>
          <category name="category_1">
            <some>
              <further>
                <nested>
                  <info info_id="1">Important Information</info>
                </nested>
              </further>
            </some>
          </category>
        </categories>
      </category>
    </categories>
  </site>
</sites>

I tried several approaches like:
/site/sites//categories/category[@name = 'category_1']
or
/site/sites//categories/category[@name != 'hidden']
or
/site/sites//categories/category/some/further/nested/info[@info_id = '1']

But all I get is something like this:
<category name="category_1">
  <some>
    <further>
      <nested>
        <info info_id="1">Important Information</info>
      </nested>
    </further>
  </some>
</category>

What is missing to preserve the parent xml data?

Any hint that will point me to the right direction would be very appreciated!

Thank & Regards,

Christian

That's generally known as an "identity transform":

http://en.wikipedia.org/wiki/Identity_transform

For XQuery look at the lowest example.

This kind of operation is much easier in XSLT than in XQuery (unless you use
XQuery updates).

Any approach that simply tries to select nodes from the existing document is
going to fail: the nodes in your output have different children from the
nodes in the input, so they must be newly constructed nodes, they cannot be
nodes in the original document, or even copies of the nodes in the original
document.

In XSLT the general pattern is:

(a) write a template rule that copies each node unchanged, calling itself
recursively to copy its children

(b) override this with a more specific rule that applies to the nodes you
don't want to copy, and which does nothing when such nodes are encountered.

In XQuery you can simulate this with a recursive function that uses
typeswitch() to test what kind of node has been supplied as an argument. But
why fight the language? Use either XSLT, or XQuery Update.

Hi Christian,

XQuery Update can be used to solve your problem fairly easily - 
something like this should do the trick:

copy $a := /
modify delete nodes $a/site/sites//categories/category[@name = 'hidden']
return $a

Thank you John!

looks promising! But after I tried to adapt it to my application I have
some trouble with XmlBeans and Saxon that I use to run my queries.

After I found out that xquery uptate was not available with the
XmlBeans/Saxon versions I used (2.3.0/8.7) I upgraded to versions
(2.4.0/9.1.0.1) and now I get this error:

Error on line 3 column 9
  XPST0003: XQuery syntax error in #...$this external; copy $#:
    Unexpected token "copy" in path expression

My query looks like this:
  declare namespace mns='http://www.mynamespace.com';
  copy $a := /
  modify delete node
$a/mns:sites/mns:site//mns:categories/mns:category[@id = "888"]
  return $a

Did someone encounter this problem before?

Thanks & Regards,

Christian

To run XQuery Update in Saxon you need the Saxon-SA version of the product,
and you need to run it with updating enabled.

Hi Micheal,

I just downloaded saxon9 (9.1.0.1) and put it in my local Maven2
repository and added it to my classpath with these dependencies:
        <dependency>
            <groupId>net.sf.saxon</groupId>
            <artifactId>saxon9sa</artifactId>
            <version>9.1.0.1</version>
        </dependency>
        <dependency>
            <groupId>net.sf.saxon</groupId>
            <artifactId>saxon9sa-jaxp</artifactId>
            <version>9.1.0.1</version>
        </dependency>
        <dependency>
            <groupId>net.sf.saxon</groupId>
            <artifactId>saxon9sa-qc</artifactId>
            <version>9.1.0.1</version>
        </dependency>
        <dependency>
            <groupId>net.sf.saxon</groupId>
            <artifactId>saxon-dom</artifactId>
            <version>9.1.0.1</version>
        </dependency>

Having this I do not get the "no query engine" error, so I guess it
XmlBeans can access Saxonias query engine.

But I still get the "XPST0003" error. Maybe "updating" is not enabled by
default - how can it be "enabled" then?

Thanks & Regards,

Christian

Saxon-SA needs to be downloaded from www.saxonica.com and activated with a
license key (free for 30 days). My log file doesn't show any recent request
in your name for a license key.

Having installed Saxon-SA and a license key, you need to invoke the query
engine in updating mode. If you're doing that from the command line, set
-update:on. If you're doing it using s9api, call setUpdatingEnabled(true) on
the XQueryCompiler.

I'm afraid I've no idea whether this can be done via XMLBeans. The
documentation at
http://xmlbeans.apache.org/documentation/conInstallGuide.html mentions some
very old Saxon releases indeed.

Thank?s for the fast and pragmatic help!

  I wonder what you want to achieve.

  Actually, I always thought that data() on an element that has child
elements was an error.  What would be the semantics of the above
example?

Curious,

what are your experiences in using XQuery across implementations?

No. It's an error if the element has been validated against a schema that
assigns it a type that has element-only content. That's not the same thing
at all.

> What would be the semantics of the above example?

For an untyped element node, data() returns essentially the same as string()
- the concatenation of the descendant text nodes.
