& XSLT Hello,

I'm a programmer for the University of Michigan Library and am  
working on extracting some data from XML files using XSLT and Java.   
It's necessary that I use regular expressions for Strings to test and  
match certain criteria for data filtering purposes.

I just found out about EXSLT and have tried using the regexp:test()  
function, but continue to get the same error again and again.  I'm  
using the Oxygen XML Editor on Mac OS X Tiger, Intel.  The Editor is  
configured to use Saxon 6.6.5.

The error message I'm getting is:

>  The URI http://exslt.org/regular-expressions does not identify an  
>  external Java class

I've tried the two following options:

>  <xsl:stylesheet version="1.1"
>      xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
>      xmlns:func="http://exslt.org/functions"
>      xmlns:regexp="http://exslt.org/regular-expressions"
>      extension-element-prefixes="regexp func">
> 
>      <func:script implements-prefix="regexp"
>          language="exslt:javascript"
>          src="regexpEXSLT/functions/test/regexp.test.js" />
>      ...
>      <xsl:if test="regexp:test($textString, '/d') = true()">

AND

>  <xsl:stylesheet version="1.0"
>      xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
>      xmlns:regexp="http://exslt.org/regular-expressions"
>      extension-element-prefixes="regexp">
> 
>      <xsl:import href="regexpEXSLT/functions/test/ 
>  regexp.test.msxsl.xsl" />
>      ...
>      <xsl:if test="regexp:test($textString, '/d') = true()">

In both scenarios, I get the same error.

I just took the xmlns statement from the EXSLT website - is there a  
different namespace I should be referring to?  I definitely have the  
source files in the locations listed.

I am somewhat new to XSLT and would appreciate any advice at all on  
how to get the EXSLT regular expressions functions working.

Thanks very much.

Bye bye,
Gaurav
