Hi Gary, Thanks for the quick response. Yes, it appears that I made an incorrect assumption. It looks like the problem doesn't have anything to do with xalan:evaluate(). I am passing a node-set consisting of multiple root nodes (a "database" of documents) as a global parameter to my stylesheet using XNodeSet. So instead of the original stylesheet I posted, consider the following modified stylesheet (which doesn't use xalan:evaluate(), a red herring): <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"; xmlns:foo="http://dummyNamespace.com";> <xsl:param name="input"/> <xsl:template match="/"> <xsl:copy-of select="$input/foo:bar"/> </xsl:template> </xsl:stylesheet> Below are some snippets from the code I am using to invoke this (some variables initialized elsewhere): private DocumentBuilderFactory bFactory; private Hashtable database = new Hashtable(); private XNodeSet nodeSet; private File databaseDir; . . . String[] fileNames = databaseDir.list(); for (int i = 0; i < fileNames.length; i++) { File file = new File(databaseDir, fileNames[i]); if (!file.isDirectory()) { DocumentBuilder builder = bFactory.newDocumentBuilder(); Document doc = builder.parse(file); database.put(fileNames[i], doc); } } NodeSet tempNodeSet = new NodeSet(); Enumeration enum = database.elements(); while (enum.hasMoreElements()) { tempNodeSet.addElement((Node)enum.nextElement()); } nodeSet = new XNodeSet(tempNodeSet); . . . transformer.setParameter("input", nodeSet); transformer.transform(source, new StreamResult(out)); I have two serious problems with the node-set that's being passed in: 1) namespaces don't work correctly, and 2) performance is horrible (worse than if I were to parse the documents repeatedly using the document() function). I posted a message to xalan-j-users earlier today about the performance problem, but it seems to have the same root as my problem with XPath queries using namespaces. My fundamental question is: What is the recommended way to construct an arbitrary XPath node-set in order to pass it in as the value of a global XSLT parameter? I have been using XNodeSet() with NodeSet() and a sequence of DOM trees. I suspect that DOM is losing the namespace information, although successful transformations still serialize the original namespace prefixes that were used. Any help would be greatly appreciated.
