This was tested with PHP5.0.4 and PHP5.1.0b1. Reproduce code: --------------- <?php $source='<?xml version="1.0" encoding="ISO-8859-1"?> <root> <child1> <child2/> </child1> </root> '; $script='<?xml version="1.0" encoding="ISO-8859-1"?> <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"; xmlns:php="http://php.net/xsl"; xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; xsl:extension-element-prefixes="php"> <xsl:output method="text"/> <xsl:template match="/"> <!-- This works! --> <xsl:value-of select="php:function(\'xslCallback\',/root/child1/child2)"/> <!-- This works! --> <xsl:value-of select="php:function(\'xslCallback\',/root/child1/childE)"/> <!-- This works! --> <xsl:value-of select="php:functionString(\'xslCallback\',/root/childE/child2)"/> <!-- This core dumps! --> <xsl:value-of select="php:function(\'xslCallback\',/root/childE/child2)"/> <!-- This (surprisingly) also core dumps (at the function-callback)! --> <xsl:variable name="indirect" select="/root/childE/child2"/> <xsl:value-of select="php:function(\'xslCallback\',$indirect)"/> </xsl:template> </xsl:stylesheet> '; function xslCallback($nodes) { return "This works!\n"; } $dom = new DOMDocument(); $dom->preserveWhiteSpace = true; $dom->loadXML($source); $xsl = new DOMDocument; $xsl->loadXML($script); $xslt = new XSLTProcessor(); $xslt->registerPHPFunctions(); $xslt->importStyleSheet($xsl); if (false === ($result = $xslt->transformToXML($dom))) { trigger_error('XSL transformation failed.', E_USER_ERROR); } print $result; ?> Expected result: ---------------- This Works!
