SAX handlers attached to an XSL transform via xslt_set_sax_handlers are not performing as expected when the target is a processing instruction. In fact, the handler is passed completely random data, generally non-printing characters, in place of the PI content. Test system is running Sablotron 0.90, on Apache 1.3.24. PHP is configured using --enable-xslt and --with-xslt-sablot (among many other options). Minimal sample code follows. <?php $xslt = xslt_create(); $args = array( "/_xml" => '<?xml version="1.0" encoding="UTF-8"?> <test />', "/_xsl" => '<?xml version="1.0" encoding="UTF-8"?> <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <xsl:template match="test"> <xsl:processing-instruction name="php"><![CDATA[ print "hello world"; ]]></xsl:processing-instruction> </xsl:template> </xsl:stylesheet>' ); function handle_pi($processor, $content, $target) { echo '<pre>'; echo "processor: $processor\n"; echo "target: $target\n"; echo "content: $content\n"; echo '</pre>'; } xslt_set_sax_handlers($xslt, array('pi'=>'handle_pi')); xslt_process($xslt, "arg:/_xml", "arg:/_xsl", NULL, $args); xslt_free($xslt); ?> PatchesPull RequestsHistoryAllCommentsChangesGit/SVN commits

As I said above, it is only segfaulting on character data handlers. Using a modified sample script, this was the backtrace I obtained. I suspect that it indicates the problem lies with Sablotron, in which case I guess you can just close the bug?
