I want to recursively iterate over an OPML file. It can have any number 
of 'outline' elements and each can have any number of children 
'outline' elements.
As I move down the tree I'll handle each by looking at their 'type' 
attribute.

here is an example snip of an OPML file:

		<outline text="Top">
			<outline text="About">
				<outline text="Website" type="link" url="http://www.yahoo.com"/>
				</outline>
			<outline text="News">
				<outline text="Today's" type='headline'>

and where my mind was headed...

   $file = file_get_contents("thefile.opml");
   $xml = new RecursiveIteratorIterator(new SimpleXMLIterator($file), 
true);
   foreach($xml as $element) {
   	if ($element == 'outline') {
     		if ($element[type] == 'link') {
                           SimonSays 'do this';
    	 	}
		if ($element[type] == 'headline'{
			SimonSays 'do that';
		}	
    	 }
   }

How far off am I?
