    Örnekte basit bir libxml hata eylemcisinin gerçeklenişi gösterilmiştir.

    <?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 .= "Uyarı $error->code: ";
    break;
    case     LIBXML_ERR_ERROR:
    $return .= "Hata $error->code: ";
    break;
    case     LIBXML_ERR_FATAL:
    $return .= "Ölümcül hata $error->code: ";
    break;
    }

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

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

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

    ?>

    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)
