Subject: [xsl] Namespace 'http://www.w3.org/2005/xpath-functions' does not contain any functions (was Re: [xsl] XSL cant check if "File exists"?) From: Laky Tang <tulaky@xxxxxxxxx> Date: Tue, 29 Aug 2006 14:04:16 -0700 (PDT) |
Thanks Mukul. I did try <?xml version="1.0" encoding="UTF-8"?> <xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:fn="http://www.w3.org/2006/xpath-functions"> ......... <xsl:if test="fn:doc-available($url)"><br /> da file does not exists</xsl:if> .......... but IE says Namespace 'http://www.w3.org/2006/xpath-functions' does not contain any functions.(tried both 2006 and 2005 in the fn namespace declaration) Firefox says "Error during XSLT transformation: An unknown XPath extension function was called." Am I missing something in the headers or should I just wait until the Candidate recommendation is implemented by most tool vendors? If so, is there an immediate solution for this (to check if a file exists)?

Message-ID: <7870f82e0608280158y191f54dcy9ae829ec63ca22ac@xxxxxxxxxxxxxx> With XSLT 2.0, you can use the doc-available(string? $uri) function.
