范例
Example #1 A libxml_get_errors() example
This example demonstrates how to build a simple libxml error handler.
<?phplibxml_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("\n", $xmlstr);if ($doc === false) { $errors = libxml_get_errors(); foreach ($errors as $error) { echo display_xml_error($error, $xml); } libxml_clear_errors();}function display_xml_error($error, $xml){ $return = $xml[$error->line - 1] . "\n"; $return .= str_repeat('-', $error->column) . "^\n"; switch ($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) . "\n Line: $error->line" . "\n Column: $error->column"; if ($error->file) { $return .= "\n File: $error->file"; } return "$return\n\n--------------------------------------------\n\n";}?>
以上例程会输出：
<titles>PHP: Behind the Parser</title> ----------------------------------------------^ Fatal Error 76: Opening and ending tag mismatch: titles line 4 and title Line: 4 Column: 46 --------------------------------------------
