Load external xml file?

Question

I have the following code (from a previous question on this site) which retrieves a certain image from an XML file:

Answer 1

Procedurally, simple_xml_load_file.

$file = '/path/to/test.xml';
if (file_exists($file)) {
    $xml = simplexml_load_file($file);
    print_r($xml);
} else {
    exit('Failed to open '.$file);
}

You may also want to consider using the OO interface, SimpleXMLElement.

Edit: If the file is at some remote URI, file_exists won't work.

$file = 'http://example.com/text.xml';
if(!$xml = simplexml_load_file($file))
  exit('Failed to open '.$file);
print_r($xml);
