Örnekler

Örnek 1 - libxml_get_errors() örneği

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";
}

?>

Yukarıdaki örneğin çıktısı:

<titles>PHP: Behind the Parser</title>

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)
