[RESOLVED] limitation of simplexml_load_file or my code ???

TheStalker

Hi every one i'm trying to build a simple script to read in a twitter feed and out the results.

The problem i am having is with the <twitter:source> tags from twitter. simplexml_load_file doe'snt seem to pick them up as a tag? i'm guessing it's somthing to do with the : in the tag?

does anyone know if this is limitation of simplexml_load_file or a way round this?

i have some simple code below that i'm testing with below.

  $feed = 'http://twitter.com/statuses/user_timeline/183703964.rss';
$tweets = simplexml_load_file($feed);

foreach($tweets->channel->item as $i => $v)
{
    echo $v->title . "<br />";
    echo $v->twitter:source . "<br />";

}

i have looked at some other peoples scripts online and they all just look over the top for what i need to do.

Any help would be great!

The ':' in the tag separates the tag name from the namespace; the 'twitter' portion is called the namespace (and is defined in the <rss> tag). See this article that explains how to work with XML docs using namespaces. Specifically, this example shows what you're going to need;

foreach ($xml->channel->item as $entry){
  ...
  //Use that namespace
  $namespaces = $entry->getNameSpaces(true);
  //Now we don't have the URL hard-coded
  $dc = $entry->children($namespaces['dc']); 
  echo $dc->publisher;
  echo $dc->creator;
}

Note that in that example, the namespace was called 'dc' instead of 'twitter'.
