Re: [Exist-open] Strange behaviour

[Jean-Christophe K. <jc...@ba...>]

Hi
I agree it's not a very common use, and certainly a misuse, but here is=20
the whole story.

I did that only because I don't want to use util:eval that takes too=20
much time. Maybe I'm wrong.

I just want to build a xquery with a few parameters :

     (::pragma exist:serialize omit-xml-declaration=3Dno::)
     xquery version "1.0";

     declare namespace f=3D"http://bluexml.org/xquery/local-functions";

     declare namespace fn=3D"http://www.w3.org/2003/05/xpath-functions";
     declare namespace util=3D"http://exist-db.org/xquery/util";

     declare namespace fd=3D"http://apache.org/cocoon/forms/1.0#definitio=
n";

     declare function f:main() as element()* {
         (: We should use util:eval to make thing more parametrizable
            but it's 20 times slower :)

	let $xpath :=3D '/document'
	let $path :=3D 'meta/author'

         for $doc in $xpath
         return (
             <fd:item>
                 <fd:value>{util:document-name($doc)}</fd:value>

(: If I use util:eval, I notice performances are very bad, because of=20
string manipulation ? no caching ? I don't know... To circumvent this=20
problem, I so decided to generate thrgouh xml+xsl my xquery. :)
                 <fd:label>{util:eval(concat($doc,$path)}</fd:label>

(: I can't do this :)
                 <fd:label>{$doc/$path}</fd:label>


             </fd:item>
         )
     };

     <fd:selection-list>
     {f:main()}
     </fd:selection-list>

Any ideas to do that ?
