The XSLT processor link identifier, created with xslt_create().

handler

The user function needs to accept four parameters: the XSLT processor, the error level, the error code and an array of messages. The function can be shown as:

Return Values

No value is returned.

Examples

Example 2665. 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));

?>

The above example will output something similar to:

array(4) {
 [0]=>
 resource(1) of type (XSLT Processor)
 [1]=>
 int(3)
 [2]=>
 int(0)
 [3]=>
 array(6) {
   ["msgtype"]=>
   string(5) "error"
   ["code"]=>
   string(1) "2"
   ["module"]=>
   string(9) "Sablotron"
   ["URI"]=>
   string(9) "arg:/_xml"
   ["line"]=>
   string(1) "4"
   ["msg"]=>
   string(34) "XML parser error 7: mismatched tag"
 }
}
