deep-equal() is an XSLT 2.0 / XPath 2.0 function, you're trying to use it
with Xalan which only implements 1.0.

Subject: Re: [xsl] comparing a part of the XML tree
I want to match the nodes *inside* the <selection> node
against the
nodes *inside* the original node.
deep-equal(selection/node(),$original/node())
Alright, that sounds logical. I assume that in this case
$original is a variable that refers to the <original> element
in the input XML file?
I constantly get an error like this when trying to use the deep-equal
function:
[error]
ERROR: 'Error checking type of the expression
'funcall(deep-equal,
[ParentLocationPath(ParentLocationPath(step("child", 14),
step("child", 15)), step("child", -1)),
ParentLocationPath(ParentLocationPath(step("child", 14),
step("child", 15)), step("child", -1))])'.'

This is my stylesheet:
[stylesheet]
<?xml version="1.0" encoding="ISO-8859-1"?> <xsl:stylesheet
version="2.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
<xsl:template match="/">
<xsl:choose>
<xsl:when
test="deep-equal(compare/selection/node(),
compare/selection/node())">true</xsl:when>
<xsl:otherwise>false</xsl:otherwise>
</xsl:choose>
</xsl:template>
</xsl:stylesheet>
[/stylesheet]
As you can see I am trying to compare the node inside the
selection element to itself, just to check if everything is working.
This is the input:
[input]
<compare>
<selection>
<z color="blue" flavor="vanilla">testje</z>
</selection> <original>
<e>
<x color="red" flavor="chocolate">testje 2</x>
<z color="blue" flavor="vanilla">testje</z>
</e>
</original>
</compare>
[/input]
