Example #1 xslt_set_error_handler() Example
<?php
// Our XSLT error handler
function xslt_error_handler($handler, $errno, $level, $info)
{
// for now, let's just see the arguments
var_dump(func_get_args());
}
// XML content :
$xml='<?xml version="1.0"?>
<para>
oops, I misspelled the closing tag
</pata>';
// XSL content :
$xsl='<?xml version="1.0"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="/">
<strong><xsl:value-of select="para"/></strong>
</xsl:template>
</xsl:stylesheet>';
$xh = xslt_create();
xslt_set_error_handler($xh, "xslt_error_handler");
echo xslt_process($xh, 'arg:/_xml', 'arg:/_xsl',
NULL, array("/_xml" => $xml, "/_xsl" => $xsl));
?>
