I apologize in advance, don't have much experience with parsing XML. If I parse with NSXMLParser it will parse the XML (validated with NSLog for each "didStartElement" and "foundCharacters" call) which I retrieve from a web service (from their site: "... output of the request is XML, which is presented in the Atom feed format").

If I print out the XML as an NSString converted from NSData received from the site with the following line:

    NSString * responseString = [[NSString alloc] initWithData:responseObject encoding:NSUTF8StringEncoding];

It prints the XML below which i also validated on a website. However, when I try to create an SMXMLDocument with the following line of code, the document when printed in NSLog prints "<(null)/>".

    SMXMLDocument * document = [SMXMLDocument documentWithData:responseObject error:&error];
    NSLog(@"Document:\n %@", document);

Is this (Atom) formatted XML not supported or am I doing something incorrectly?

Wow, i apologize. I first downloaded the non-arc version but my test build uses ARC so i downloaded that and replaced the original files i put in my test program. Once i put an NSLog statement in a function in your class, it recompiled, re-linked and it works. So, it must have failed due to caching the wrong version of your files.

Sorry to waste your time!
