1.2.1541. ext/libxml

Extension libxml.

These functions/constants are available as of PHP 5.1.0, and the following core extensions rely on this libxml extension: DOM, libxml, SimpleXML, SOAP, WDDX, XSL, XML, XMLReader, XMLRPC and XMLWriter.

<?php

// $xmlstr is a string, containing a XML document.

$doc = simplexml_load_string($xmlstr);
$xml = explode(PHP_EOL, $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] . PHP_EOL;
    $return .= str_repeat('-', $error->column) . '^'.PHP_EOL;

    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) .
               PHP_EOL.'  Line: '.$error->line .
               PHP_EOL.'  Column: '.$error->column;

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

    return $return.PHP_EOL.PHP_EOL.'--------------------------------------------'.PHP_EOL.PHP_EOL;
}

?>
