Number 1"></file>
so now how do I get an attribute from it such as url, or name. I
saw in NSXMLElement documentation that it had an attribute thing but
I can't figure out how to convert the node to NSXMLElement to get
the attribute.
The nodes are elements. Change "NSXMLNode" to "NSXMLElement" in your
code (adding a type-cast if necessary), and then call -
attributeForName:.
If you want to learn XPath syntax (google it for lots of tutorials)
you can do all of this stuff with one or two lines of code, using -
nodesForXPath:error:; but XPath has its own learning curve.
