I have the following code: NSString *subtitle = [[[node elementsForName:@subtitle] objectAtIndex:0] stringValue]; NSString *duration

  • 0

I have the following code:

NSString *subtitle = [[[node elementsForName:@"subtitle"] objectAtIndex:0] stringValue];
NSString *duration = [[[node elementsForName:@"itunes:duration"] objectAtIndex:0] stringValue];

The first line works perfectly. The second line though won’t work. I assume it has something to do with namespaces, but I’m pretty new to all of this so I would appreciate any guidance. Thank you!

It turns out that I can use the elementsForLocalName:URI: to read the element correctly. Now the problem is that since I am using the TouchXML library, it doesn’t seem like that method has been mapped over to the CXMLElement structure (see here).

So the question now is: how can I convert a CXMLElement to an NSXMLElement so that I can use that method?

    “itunes” is the namespace identifier. It doesn’t actually have any significance on its own, it just links a URI with the element in question. It looks like you’re using the iTunes RSS extensions, which live under the namespace http://www.itunes.com/dtds/podcast-1.0.dtd.

    So, for namespaced elements, I think (I’m not familiar with Objective-C or NSXML :P) you want to use elementsForLocalName instead:

    [node elementsForLocalName: @"duration" URI: @"http://www.itunes.com/dtds/podcast-1.0.dtd"]

    For the answer to the second question, see comments below.
