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"
  }
}
