What you’re asking for is a one-liner. There is a little bit of a learning curve for learning the syntax, but it’s really worth it (you can find online tutorials pretty easily by searching.) So instead of NSXMLParser, use the higher level NSXMLDocument (which can even fetch the URL for you) and then use the XPath methods on it. [Um, except now it occurs to me that you didn’t specify what OS you’re on, and last I heard iOS didn’t have NSXMLDocument yet… If you’re using iOS, it’s best to specify that explicitly, since a lot of us old crusties here will assume OS X unless otherwise stated.] —Jens
