Patch for external URL

Thanks for the patch. Needs testing, but as soon as it's either tested by me or someone else I'm happy to commit. =)

Patch didn't apply, but here's the function:

/**
 * This function receives the URL to an external XML document and 
 * returns the contents of the document as a string.
 * 
 * @param $file 
 * (string) URL to an external XML file.
 * 
 * @return
 * (string) The contents of the XML file as a string ready
 * to be parsed or FALSE if the file could not be retrieved.
 */
function xml_parser_load_url_xml($url) {
  $response = drupal_http_request($url);   
  // if there was an error handle it
  if ($response->code != 200) {
    watchdog('xml_parser', t('Could not retrieve XML file from: '.$url), array(), WATCHDOG_ERROR);
    return FALSE;
  }
  else {     
    $str = $response->data;
    return $str;
  }
}

I'll test it and see if it works for me. :)

Works just fine. Here's a reroll in current patch format with a little bit of coding standards cleanup.

Thanks! Will check it out.

Committed to 6.x-1.x-dev. Thanks again!
