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));
?>`

El resultado del ejemplo seria algo similar a:

    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"
      }
    }
