Parsing SimpleXML Object data

How to get “file_url” from this data?

Response can contain few objects, and how to parse it?

Code that I use:

<?php
$r34data = simplexml_load_file('https://rule34.xxx/index.php?page=dapi&s=post&q=index&tags=green_hair&limit=2');
print_r($r34data);

Response:

Answer

Hi
You can conver it to the array and work with is easy

libxml_use_internal_errors(TRUE);

$objXmlDocument = simplexml_load_file("https://rule34.xxx/index.php?page=dapi&s=post&q=index&tags=green_hair&limit=2");

if ($objXmlDocument === FALSE) {
    echo "There were errors parsing the XML file.n";
    foreach(libxml_get_errors() as $error) {
        echo $error->message;
    }
    exit;
}

$objJsonDocument = json_encode($objXmlDocument);
$arrOutput = json_decode($objJsonDocument, TRUE);

echo "<pre>";
print_r($arrOutput);
