xslt_set_error_handler -- Set an error handler for a XSLT processor

Description

void xslt_set_error_handler ( resource xh, mixed handler )

Set an error handler function for the XSLT processor given by xh, this function will be called whenever an error occurs in the XSLT transformation (this function is also called for notices).

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: error_handler ( resource xh, int error_level, int error_code, array messages )

Examples

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));

?>

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"
  }
}
