    Ejemplos

    Ejemplo #1 Ejemplo con libxml_get_errors()

    Este ejemplo muestra cómo crear un gestor de errores libxml simple. 

    <?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("\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 .= "Advertencia $error->code: ";
            break;
         case LIBXML_ERR_ERROR:
            $return .= "Error $error->code: ";
            break;
        case LIBXML_ERR_FATAL:
            $return .= "Error fatal $error->code: ";
            break;
    }

    $return .= trim($error->message) .
               "\n  Línea: $error->line" .
               "\n  Columna: $error->column";

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

    return "$return\n\n--------------------------------------------\n\n";
}

?>

    El ejemplo anterior mostrará:

    <titles>PHP: Behind the Parser</title>
----------------------------------------------^
Error fatal 76: Opening and ending tag mismatch: titles line 4 and title
  Línea: 4
  Columna: 46

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

    Please beware that the column property seems almost always to be invalid. I thought it only occurred when the line in question was long (and I was just about to submit a bug report with an example), however, at the time of posting, you can even see the problem in the example provided on this page: line 4 does not even have 46 characters. Where the XML line is long, the difference can be very large.

This property comes from the libxml extension, so in any case I don't think this is a PHP bug, however it is worth knowing that the value might be totally unreliable to save some confusion.

The PHP documentation page for the libXMLError class gives some indication, stating:

"This property isn't entirely implemented in libxml and therefore 0 is often returned."

(My libxml version: 2.9.1)
