& XSLT I'm sure this isn't the first post about this but I have googled and written to other
 people but nothing has given me the difinitive solution.

Firslty, I tried an example form the exslt web site

<?xml version="1.0" ?> 

<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="/home/anthony/downloads/exslt/orig_exslt/regexp/regexp.xsl" /> 

<xsl:template match="/"> 
  <xsl:for-each select="regexp:match('http://www.bayes.co.uk/xml/index.xml?/xml/utils/rechec
ker.xml', '(\w+):\/\/([^/:]+)(:\d*)?([^# ]*)')"> 
    Part <xsl:value-of select="position()" />  = <xsl:value-of select="." />
  </xsl:for-each> 
</xsl:template> 

</xsl:stylesheet> 

and using xsltproc, I get ...........

xmlXPathCompOpEval: function match not found
XPath error : Unregistered function
xmlXPathCompiledEval: 1 object left on the stack

So, I renamed the exslt regexp namespaces to regular-expressions and now I just get ........
......

 xmlXPathCompOpEval: function match not found
XPath error : Unregistered function
xmlXPathCompiledEval: 1 object left on the stack

Now, there are several things. I'm using xsltproc on Ubuntu which I believe has been compile
d against preinstalled libs ........ libxml 20622, libxslt 10115 and libexslt 812. But, beca
use I couldn't get things working, I downloaded the files from exslt.org and am using them l
ocally with the preinstalled xsltproc.

Is that causing conflicts?

I'd really like to get this working to use at work. It'll save a lot of hassle if I do.

I'd like to think I don;t need hand-holding but any pointers in the right direction would be
 great.
