Hi, I don't think the variables will have been replaced by their values when the extension is called. Instead you could create a result tree fragment and call an extension function passing in the result tree fragment such as in the following example.
Stylesheet: <?xml version="1.0"?> <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"; xmlns:xalan="http://xml.apache.org/xalan"; xmlns:myclass="MyClass" extension-element-prefixes="myclass" version="1.0"> <xalan:component prefix="myclass" functions="process"> <xalan:script lang="javaclass" src="MyClass"/> </xalan:component> <xsl:variable name="var1" select="'This is variable 1.'"/> <xsl:variable name="var2" select="'This is variable 2.'"/> <xsl:variable name="rtf"> <elem1 number="1"> <xsl:value-of select="$var1"/> </elem1> <elem2 number="2"> <xsl:value-of select="$var2"/> </elem2> </xsl:variable> <xsl:template match="/"> <out> <xsl:value-of select="myclass:process($rtf)"/> </out> </xsl:template> </xsl:stylesheet> MyClass.java: import org.w3c.dom.NamedNodeMap; import org.w3c.dom.Node; import org.w3c.dom.NodeList; public class MyClass { public void process(NodeList rtf) { for (int i = 0; i < rtf.getLength(); i++) { processNode(rtf.item(i), ""); } } private void processNode(Node node, String indent) { System.out.println(indent + "Name: " + node.getNodeName() + ", Value: " + node.getNodeValue()); NamedNodeMap map = node.getAttributes(); for (int i = 0; i < map.getLength(); i++) { Node attr = map.item(i); System.out.println(indent + " Attr: " + attr.getNodeName() + ", Value: " + attr.getNodeValue()); } NodeList nodes = node.getChildNodes(); for (int i = 0; i < nodes.getLength(); i++) { processNode(nodes.item(i), indent + " "); } } } The output from the processNode method is: Name: #document, Value: null Name: elem1, Value: null Attr: number, Value: 1 Name: #text, Value: This is variable 1. Name: elem2, Value: null Attr: number, Value: 2 Name: #text, Value: This is variable 2.

I start to write simple extension element, but a problem occurs. I want to access extension element's subelements in java+xalan. My xsl contains following block of code: <my-ext:request> <body><xsl:value-of select="$body"/></body> <contentType>text/html</contentType> <metaData><![CDATA[<?xml version="1.0" encoding="utf-8"?>]]><metaData> <xsl:value-of select="$metaData"/> </metaData> </metaData> </my-ext:request> In extension element Java-method i have "XSLProcessorContext context" and "ElemExtensionCall elem". I can get contentType by calling for example "elem.getFirstChild().getNextSibling().getFirstChild().getTextContent()", but i want to access subelements by tag name(for example, by elem.getElementsByTagName("metadata"), or XPath). I have no idea how to access in java content of $body variable and xml - encapsulated $metaData. All google - examples shining no light. Is simple xslt - subelements access method exist? Big thanx for help. P.S. Sorry for my English. I hope you understand me. -- View this message in context: http://www.nabble.com/Extension-element-with-subelements-tf4395665.html#a12534751 Sent from the Xalan - J - Users mailing list archive at Nabble.com.
