XML : PHP XML select node without naming it

I have a XML which is on an external server, recalling this is no problem.
Now the problem is, I want to select a path, without naming it.

So for example:

  <data num_results="2">     <node>        <raw_text>        </raw_text>     </node>  </data>    

And i now recall it like this:

  $xml = simplexml_load_file($link);  foreach($xml->data->node as $report) {     process;  }    

And i want to recall it like this:

  $xml = simplexml_load_file($link);  foreach($xml->data->[something without naming it "node"] as $report) {     process;  }    

How do i do this?

Cheers!
