Libxsl doesn't like the {$foo} at that place:


Error xpath.c:6566: Invalid expression
{$foo}//BAR
^
Error xpath.c:9123: Invalid expression
{$foo}//BAR
^
xsl:copy-of : could not compile select expression '{$foo}//BAR'

How?

This is my (now stripped down) XSL-Sheet:



<?xml version="1.0" ?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
        version="1.0">


<xsl:template match="/">

<xsl:variable name="foo">
<FOO>
        <BAR arg="1">
        test
        </BAR>
</FOO>
</xsl:variable>

<xsl:copy-of select="$foo//BAR"/>

</xsl:template>

</xsl:stylesheet>



Xalan-C:
