For parsing XML I generally treat it as a DOM document:

$doc = new DomDocument();
$doc->load("your.xml");
$tags = $doc->getElementsByTagName("tag");

There's also Simple XML:

$doc = simplexml_load_file('your.xml');

PHP null.

ok, it i wanted to go thru each tag which one would you recommend the simple xml or treat as dom?

Personally I prefer DOM. Simple XML, I believe, requires PHP 5.

I prefer DOM because I work with JavaScript a bit so I'm use to thinking that way. Simple XML has some power over DOM in some instances though. I suggest doing some reading on articles that compare the two approaches so you can decide which will best suit the work your doing.
