[xsl] regex in XSLT 2.0: problems with XPath

[Manuel Souto Pico <manuel.souto@xxxxxxxxxxxxxx>]

Hi again,

I was glad to find out that XSLT 2.0 supports regular expressions 
(although I was surprised they weren't supported already in 1.0). I'm 
trying to use them to capture some element if its contents match some 
expression.

It seems that I need to use XSLT 2.0, so I believe I must change the 
definition in the XSLT document (see 2nd line in the preamble of my doc 
just below) as well as the processor version (I used Saxon 6.5.5. with 
XSLT 1.0, now I've chosen Saxon-SA 9.1.0.3). I do all of this in oXygen 
10 and I haven't done anything else to use XSLT 2.0.

<?xml version="1.0" encoding="ISO-8859-1"?>
<xsl:stylesheet version="2.0" 
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
   <xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes" />
(...)

The area of code where I want to use regular expressions look like 
(using the syntax matches(elem, expr):

                               <xsl:for-each 
select="../category[@domain='tag'][@nicename]">
                                   <xsl:if 
test="matches(../category[@domain='tag'][@nicename], 
&lt;!\[CDATA\[economia\]\]&gt;)">
                                       <descrip type='subjectfield'>
                                           <xsl:value-of 
select="../category[@domain='tag'][@nicename]"/>
                                       </descrip>   
                                   </xsl:if>   
                               </xsl:for-each>

However, when I run the debugger, I get this error message:

   SystemID: vds2tbx.xsl
   Description: Failed to compile stylesheet. 1 error detected.

   SystemID: vds2tbx.xsl
   Location: 37:0
   Description: XPath syntax error at char 47 on line 37 in
   {...y[@domain='tag'][@nicename]...}:
       Node constructor expressions are allowed only in XQuery, not in
   XPath
   URL: http://www.w3.org/TR/xpath20/#ERRXPST0003

Googling that error I couldn't find any useful pages, so I am quite 
stuck. What am I doing wrong? Am I using the old version of XPath?

I hope my questions are interesting for the list!
Regards, Manuel
