       Example #1

	      xslt_set_error_handler(3) 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"
		}
	      }
