convert 5.1.2 code php to 5.0.4

I've been doing research on why my code is not working and it seems, and please correct me if I am wrong, it is due to this part  

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

it appears SimpleXML is not supported in 5.0.4, needs to 5.1.x, I cannot change the PHP version on the server, is it possible to convert this code so it will work with 5.0.4.

Any version of PHP5 supports SimpleXMLElement as far as I'm aware. Only certain elements of the class require a higher version, but your script should not be affected unless you want to start manipulating it by e.g. adding elements.

One possibility is that you do not have allow_url_fopen set to On. You can change this in your php.ini file. If you have shared hosting, you'll likely need to ask your provider to change it, there is no other way around that as far as I know.

A simple test will show if it is enabled. Create a new file with the following contents:

<?php
$test = file_get_contents("http://www.google.com");
echo $test;
?>

If you see the google homepage, then the problem is not that!

If you can get the contents of the page via what rjdown suggested. Try throwing the contents into simplexml like this:

$xml = simplexml_load_string($string);
print_r( $xml );

SimpleXML is 5.0+

could you try changing line

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

into

$xml = simplexml_load_file($xml_request_url);

and see what you get?
