Hi, I'm trying to use the extension 'difference' function, whose entire documentation consists of:
"Implemented in org.apache.xalan.lib.Extensions, difference(node-set1, node-set2) returns a node-set with the nodes in node-set1 and not in node-set2." -- http://xml.apache.org/xalan-j/extensionslib.html#difference I have the following XSL: <?xml version="1.0"?> <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"; xmlns:xalan="http://xml.apache.org/xalan"; extension-element-prefixes="xalan" > <xsl:template match="/"> <xsl:variable name="treefrag1"> <target>a</target> <target>b</target> <target>c</target> </xsl:variable> <xsl:variable name="treefrag2"> <target>a</target> <target>b</target> </xsl:variable> <xsl:for-each select="xalan:difference(xalan:nodeset($treefrag1), xalan:nodeset($treefrag2))/*"> <xsl:message> Got: <xsl:value-of select="."/> </xsl:message> </xsl:for-each> <xsl:message>Finished!</xsl:message> </xsl:template> </xsl:stylesheet> Ie, two result fragments converted to nodesets, which I then want to determine the 'difference' of. I'm expecting a nodeset containing just <target>c</target>. Here's what I get: $ java org.apache.xalan.xslt.Process -in small.xsl -xsl small.xsl -out /dev/null Got: a Got: b Got: c Finished! Can anyone see what's wrong here? Btw, assuming Xalan follows the semantics of exslt's set:difference, this may be relevant: http://www.exslt.org/set/functions/difference/index.html But that demonstrates the node-set coming from a select on the source document, not from an xalan:nodeset(). Could that make a (ahem) difference? Thanks, --Jeff
