PHP/XML help

[Vince889]

Okay... this one is kind of complicated... for me, anyways.But I will try to be as clear as possible.

 

I am using PHP's SimpleXML plugin to handle this XML document generated from Yahoo's API. Incase you aren't familiar, Yahoo's API generates thisupon request.

 

As you can see, the queries the Yahoo Answers database and returns some questions on "PHP". I need to loop through this document and grab the Subject, Content, Date, Link, and Chosen Answer nodes from each Question node. And of course, they will need to be stored in a variable for later echo'ing.

 

I think XPath is what I should be doing, but I have no idea about how I should loop through it and target those specific nodes only.

 

$req = "http://answers.yahooapis.com/AnswersService/V1/questionSearch?appid=YahooDemo&query=php";
$res = file_get_contents($req);
$xml = simplexml_load_string($res);

 

That's about as far as I got. Can anyone help? Also, if I'm not clear enough, please let me know!
