The website says this about xalan:evaluate(): "evaluate (xpath-expression) function returns the result of evaluating the xpath-expression in the current XPath expression context (automatically passed in by the extension mechanism)."[1] It appears that namespace prefix-bindings are not being included in the evaluation context. For example: <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"; xmlns:foo="http://dummyNamespace.com"; xmlns:xalan="http://xml.apache.org/xalan"; extension-element-prefixes="xalan"> <xsl:param name="xpath" select="'/foo:bar'"/> <xsl:template match="/"> <xsl:copy-of select="xalan:evaluate($xpath)"/> </xsl:template> </xsl:stylesheet> This should select all top-level bar elements in the "foo" namespace. But it selects nothing. It works fine when selecting elements not in a namespace. I am using xalan-j_2_1_0. Thanks for your time, Evan Lenz XYZFind Corp.
