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));



?>

  [3]=>
  array(6) {
    ["msgtype"]=>
    string(5) "error"
    ["code"]=>
    string(1) "2"
    ["module"]=>
    string(9) "Sablotron"
    ["URI"]=>
    string(9) "arg:/_xml"
    ["line"]=>
