Subject: [xsl] Maths functions in a stylesheet? From: "Derek Hohls" <dhohls@xxxxxxxxxx> Date: Fri, 25 Feb 2005 18:40:31 +0200 |
If any XSLT gurus could help with this... I have a "maths functions" stylesheet, adapted from another source - <?xml version="1.0"?> <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"; xmlns:xalan="http://xml.apache.org/xalan"; xmlns:maths="http://www.mydomain.com/maths"; extension-element-prefixes="maths" version="1.0"> <xalan:component prefix="maths" elements="rules" functions="sine cosine abs pi"> <xalan:script lang="javascript"> function sine(thisValue) { return Math.sin(thisValue); } function cosine(thisValue) { return Math.cos(thisValue); } function abs(thisValue) { return Math.abs(thisValue); } function pi() { return 3.141592653589790; } </xalan:script> </xalan:component> </xsl:stylesheet> Called like this: <?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"; xmlns:maths="http://www.mydomain.com/maths"; extension-element-prefixes="maths"> > <xsl:include href="functions.xsl"/> <xsl:template match="/"> <xsl:variable name="foo" select="maths:pi()" /> </xsl:template> </xsl:stylesheet> I get : An Error Occurred java.lang.RuntimeException: Unknown error in XPath. cause: java.lang.RuntimeException: Unknown error in XPath. when running this with Cocoon 2.1.5 (withe default build with Xalan). Thanks Derek
