Hi Gleb,

Could the prefix in front of the return call be missing? (e.g., local:return, depending on how you defined this function)

By default (if you have not changed it), the default function namespace is the builtin one (also available through fn:), so just typing "return" will look up among builtin functions (fn:return, which as far as I know does not exist).

Does this help?

Kind regards,
Ghislain

That is your error. Xquery does not have a return function.
Without seeing more context it's not clear what the query should be.

This is actually very straightforward. "return" is a keyword, used in 
FLWOR expressions and a few other places. There is no standalone 
"return" in XQuery. Thus:

    let $x:=0 return (23)

is a valid (if uninteresting) FLWOR expression that is equivalent to the 
even less interesting (but still valid) expression:

    (23)

And a standalone "return" is illegal:

    return (23) (: error :)

Where you have included parentheses below, you are calling a function 
named "return" and XQuery works as expected. It's a bad idea to name a 
function using a keyword as a name, but XQuery allows it. If you replace 
"return(...)" with "foo(...)" in the expressions below, the intended 
meaning will be clear.

The last two XQuery expressions should return errors (and do in the 
online Zorba XQuery processor I tried them in). As noted above, this is 
because there is no standalone use of the "return" keyword -- either the 
processor you are using has a bug or you haven't shown us the entire 
expression.

Thanks,

Sorry, I think I neglected to include a let before a couple of the 
returns.  But my main point was the unusual (and probably unfamiliar to 
people used to other languages) change in the interpretation of 
parentheses when they follow the return keyword and when they follow the 
return function.

Admittedly the idea of defining a function with the same name as a 
keyword is contrived and ill-advised, right up there with C++ operator 
overloading.  It just occurred to me on reading Michael Kay's comment 
'There is no function called "return"' that there actually could be one.

I thought that might be the case.

That is confusing.

The other thing that confuses people is that functions don't use the 
"return" keyword and instead just return the result of evaluating the 
contained expression.

ha that's great (if a little contrived):

declare default function namespace "x";
declare function return ($x) { $x+1 };
return (23)

returns 24

but add a let:

declare default function namespace "x";
declare function return ($x) { $x+1 };
let $foo := 1
return (23)

returns 23

(tested using Saxon HE 9.3.0.5.)

Yes that is contrived, I think it's clearer if you write it like this

declare default function namespace "return";
declare variable $return := 23;
declare function return ($return) { $return+1 };
return ($return)

That is indeed much clearer, thanks David.

Hi all,

This time I have a rather challenging task at hand. ?Let me first describe the use case.? We have lots of product information stored in XML.? Some of that information describes

. Features and benefits
. Technical summary

One of the problems is a lot of products had e.g. the same features and benefits as they are of the same product family or group.? But as we stored that info per product it got duplicated.? Now we want to deduplicate that info by generating DITA maps and topics (both are just XML).? Now for simplicity let's assume we generate the following content for product1 and product2.? The goal is to get from INPUT to OUTPUT by checking if the body of the linked topics are duplicates, next create 1 generic topic and rewrite the links in the map to? point to that single topic.? I have XSLT / XQuery (XMLDB) and Java at my disposal to get the job done.? I'm not sure what will be the easiest way to get the job done. ?Keep also in mind that my INPUT will contain a few 1000 files (maps and linked topics) and I will need to deduplicate the whole set ;-)

Thx upfront for any input,
Robby ?

Dear Robby,

Zorba XQuery processor currently supports a data cleaning module 
(look for data cleaning in http://www.zorba-xquery.com/html/modules)
that we may want to try.

In principle, the requirements associated to your data de-duplication problem can be 
addressed by writing an XQuery program that invokes some of the functions available
in this data cleaning module.

We would appreciate your feedback if you decide to do so and please let us know if we
can help somehow.

Thanks.
Best Regards,
Helena Galhardas

Hi,

I'm currently trying out a pure XSLT solution.  As an add-on, I'd like to mention I like where Zorba is going although I did not have the time to use it yet. I really need to take a closer look once I have time at the documentation.  

Thx for the tip by the way.

Robby

Dear Robby,

Zorba XQuery processor currently supports a data cleaning module (look for data cleaning in http://www.zorba-xquery.com/html/modules)
that we may want to try.

In principle, the requirements associated to your data de-duplication problem can be addressed by writing an XQuery program that invokes some of the functions available in this data cleaning module.

We would appreciate your feedback if you decide to do so and please let us know if we can help somehow.

Thanks.
Best Regards,
Helena Galhardas

Subject: [xquery-talk] moving an element from last child to next sibling
Message-ID: <CCAC0799.47A2E%martin.mueller@mac.com>

I have used the xquery typeswitch function to transform elements from a TEI
file, but I am stymied by a task involving the following fragment:

    <closer>
               <signed>Your ever affectionate WOODVILLE.</signed>
               <postscript>
                  <p>P.S. You have a house, within a mile of York; where we
have spent many happy days?<q rend="inline">"Days of ease, and nights of
pleasure."</q> Who knows but we may there recover our juve?nile tastes and
passions! impossible! As well when advanced in life, might we hope to
reco?ver our youth, <hi>in those fields where we once were young.</hi>?But
is that house untenanted? Will you be our host? Or have you lett, or lent
it?</p>
               </postscript>
            </closer>

I want to move the <postscript> element from its position as the last child
of <closer> into the position of right sibling of <closer> so that the
desire output would look like this:

 <closer>
           <signed>Your ever affectionate WOODVILLE.</signed>
               
 </closer>
<postscript>
                  <p>P.S. You have a house, within a mile of York; where we
have spent many happy days?<q rend="inline">"Days of ease, and nights of
pleasure."</q> Who knows but we may there recover our juve?nile tastes and
passions! impossible! As well when advanced in life, might we hope to
reco?ver our youth, <hi>in those fields where we once were young.</hi>?But
is that house untenanted? Will you be our host? Or have you lett, or lent
it?</p>
</postscript>


How do I do this? In a typeswitch function the different tasks relating to
elements are carried out by subsidiary function. Here is the postscript
function that simply passes through the element:

declare function eccoparse:postscript($node as element(tei:postscript)) as
element() 
{
<postscript>{$node/@*}{eccoparse:recurse($node)}</postscript>
};



I know how to various things that would change the postscript element but
leave it in its current place. But how do I put it in another place without
changing anything in it?  Is this a task that should be done at the level of
the parent element?



I'll be grateful for any advice.

There are at least a couple of different approaches to this via the typeswitch 
strategy, but I think the simplest would be:

1. In your function for closer, recurse over the child nodes as usual (which I 
assume will output a <closer> element, or whatever you transform it to), then 
process your postscript children:

    for $ps in $node/tei:postscript
    return <postscript>{$ps/@*, eccoparse:recurse($ps)}</postscript>

2. Extend your postscript function so it returns null if the postscript is a 
child of <closer>:

    declare function eccoparse:postscript($node as element(tei:postscript)) as
    element()*
    {
      if ($node/parent::tei:closer) then ()
      else <postscript>{$node/@*}{eccoparse:recurse($node)}</postscript>
    }

Speaking as someone who wrote a lot of pseudo-templates in XQuery before 
MarkLogic added an XSLT 2.0 parser to their product, this is one area where XSLT 
is a lot more pleasant to use, if that's a possibility.

Hear, hear - we abandoned using xquery for transformations as well for 
that reason.

When I was still struggling with that, I found myself trying to write a 
pattern-matching system (basically something like xslt implemented in 
xquery), but it was too difficult in XQuery 1.0.

Now I wonder whether something like this is feasible using xquery 3.0 
features.  Maybe not worth the effort, given the existence of xslt, but 
at least you could imagine defining a map of XPath to function, 
iterating over a tree, matching patterns and calling functions...

I think that with maps* and higher-order functions you could do 
something quite powerful; however the resulting code might be very 
cryptic to the uninitiated.

* Sadly, maps are not in XQuery 3.0, though John Snelson has shown how 
they can be implemented using higher-order functions...

Im not quite sure what the context of your query is, but this really
does not look right to me. I would try inverting the order of
execution, you can often use the set operators like union or intersect
to bring together faceted queries -

e.g.

let $base := if($person) then
//foo/bar[contributions/person/@val = $person]
else
//foo/bar
return

let $next := if($other) then
//foo/bar[other = $other]
else
//foo/bar
return

subsequence($base intersect $next, $off, $num)

Another option is actually to build your predicates as a string using
concatenation, and then use util:eval to evaluate the query.

Your query can be made much more efficient yet.

Indexes made a huge difference in eXist, but you need to get your
query correct first, so that you know which indexes you need.
