PHP SimpleXMLElement load XML with xmlns

Question

I'm trying to load an XML file from a URL using SimpleXMLElement.

My code basically looks like this:

$xml = new SimpleXMLElement($url, null, true);

$url is the string of the URL containing XML response. I can load it just fine if there is no "xmlns" in the XML. When there is "xmlns", it'll cause runtime error:

Warning: SimpleXMLElement::__construct() [simplexmlelement.--construct]: http://test.cloudapp.net:8080/api/missiondetails/1:1: parser error : Start tag expected, '<' not found in /var/www/test.com/test.php on line 10

This is the example of the XML format:

<MissionDetails xmlns:i="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://schemas.datacontract.org/2004/07/Test.DataTransferObject"></Mission>

Anybody knows how to load XML with "xmlns" in the root node?

Thanks beforehand.

Answer 1

What version of PHP are you using? The data_is_url (3rd) argument for the SimpleXMLElement constructor was only added in 5.1.2.

Also, the second argument should be an integer, 0 by default.

Perhaps try using simplexml_load_file() instead
