"XSLT transformation failed" why?

Question

Firefox tells me "Error during XSLT transformation: XSLT transformation failed." for an XML file that uses the following XSL file:

<?xml version='1.0' encoding='UTF-8'?>
<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:dxp='http://schemas.google.com/analytics/2009' 
xmlns:gd='http://schemas.google.com/g/2005'
xmlns:fn='http://www.w3.org/2005/xpath-functions'>
<xsl:output method="html"/>
<xsl:template match="/">
<html><head><title>...</title></head><body>
<table frame='border' rules='all'>
<tr><th>site</th><th>week</th><th>pages</th><th>pageviews</th></tr>
<xsl:for-each select='feeds/feed/week'>
  <xsl:for-each-group select='entry' group-by='fn:concat(
    if (fn:matches(dxp:dimension[@name="ga:pagePath"]/@value, "^/sales"))
      then "/sales"
      else "non-/sales",
    " referred from ",
    if (fn:matches(dxp:dimension[@name="ga:referralPath"]/@value, "^/forsale"))
      then "/forsale"
      else "non-/forsale"
    )'>
    <tr>
      <td><xsl:value-of select='../dxp:tableName'/></td>
      <td>
        <xsl:value-of select='../dxp:startDate'/>-<xsl:value-of select='../dxp:endDate'/>
      </td>
      <td><xsl:value-of select='current-grouping-key()'/></td>
      <td><xsl:value-of select="sum(current-group()/dxp:metric/@value)"/></td>
    </tr>
  </xsl:for-each-group>
</xsl:for-each>
</table></body></html>
</xsl:template>
</xsl:stylesheet>

I can't figure out what might be wrong with this. Anyone know?

(Obviously, if further info is needed from me in order that someone be able to answer this, I'll be glad to provide that info: please comment asking for it. I don't even know what kind of info might be helpful.)

EDIT: Someone mentioned in an answer that my including the XML file might help. It's very long, but its general structure is:

Why do you think that Firefox uses an XSLT 2.0 processor?

AFAIK, this isn't so.

Obviously, an XSLT 1.0 processor raises some kind of error when given an XSLT 2.0 transformation that contains non-XSLT 1.0 instructions, such as <xsl:for-each-group> .

Can anyone confirm for certain whether Firefox (9.0.1) can handle XSLT 2.0? – msh210 Dec 22 '11 at 15:57
@msh210: Better search for "XSLT 2.0 support in Firefox" and confirm that there isn't any official announcement for such support. That no major browser today supports XSLT 2.0 is a well-known fact -- I wonder why you believe XSLT 2.0 is supported. – Dimitre Novatchev Dec 22 '11 at 16:47

Do you have an example xml file lying around :) Might help investigating what is wrong with the xsl.

At my first look, I saw a namespace prefix ga, which is not mentioned in the namespace list in the xsl:stylesheet element in your xsl.

I also doubt if the group-by attribute in the xsl:for-each-group works. Seems like you try to dynamically set the value of the group-by attribute by concatenating some xpath results to compose an xpath expression. That is not possible.

It's a very long XML file. Shall I paste its general structure into the question? – msh210 Dec 20 '11 at 21:07
I agree. The root element containing 2 or 3 elements should suffice – Peter Hofman Dec 20 '11 at 21:23
@Murph, Peter, I've edited the question to include the XML. Thanks for your attention. – msh210 Dec 20 '11 at 21:28
The last part of my answer is the actual answer to your question. – Peter Hofman Dec 20 '11 at 21:34
Re impossibility of group-by with concat: Yet I see references to the possibility of such a thing; e.g., http://stackoverflow.com/a/2768949. – msh210 Dec 20 '11 at 21:44
Hmmm, I stand corrected :( I gotta look into it a bit deeper I guess. It has been a while since I actively used XSLT. – Peter Hofman Dec 20 '11 at 21:56
