EXAMPLES
       Example #1

	      A libxml_get_errors(3) example

	       This example demonstrates how to build a simple libxml error handler.

	      <?php

	      libxml_use_internal_errors(true);

	      $xmlstr = <<< XML
	      <?xml version='1.0' standalone='yes'?>
	      <movies>
	       <movie>
		<titles>PHP: Behind the Parser</title>
	       </movie>
	      </movies>
	      XML;

	      $doc = simplexml_load_string($xmlstr);
	      $xml = explode("
", $xmlstr);

	      if (!$doc) {
		  $errors = libxml_get_errors();

		  foreach ($errors as $error) {
		      echo display_xml_error($error, $xml);
		  }

		  libxml_clear_errors();
	      }

	      function display_xml_error($error, $xml)
	      {
		  $return  = $xml[$error->line - 1] . "
";
		  $return .= str_repeat('-', $error->column) . "^
";

		  switch ($error->level) {
		      case LIBXML_ERR_WARNING:
			  $return .= "Warning $error->code: ";
			  break;
		       case LIBXML_ERR_ERROR:
			  $return .= "Error $error->code: ";
			  break;
		      case LIBXML_ERR_FATAL:
			  $return .= "Fatal Error $error->code: ";
			  break;
		  }

		  $return .= trim($error->message) .
			     "
  Line: $error->line" .
			     "
  Column: $error->column";

		  if ($error->file) {
		      $return .= "
  File: $error->file";
		  }

		  return "$return

--------------------------------------------

";
	      }

	      ?>

	      The above example will output:

	      <titles>PHP: Behind the Parser</title>
	      ----------------------------------------------^
	      Fatal Error 76: Opening and ending tag mismatch: titles line 4 and title
		Line: 4
		Column: 46

	      --------------------------------------------
