iPhone Parsing Enclosure url tag?

Question

I am having an issue with a blog I am working on. The method I am using to parse is:

NSArray *channels = [rootElement elementsForName:@"channel"];
for (GDataXMLElement *channel in channels)
{
    NSString *blogTitle = [channel valueForChild:@"title"];
    NSArray *items = [channel elementsForName:@"item"];
    for (GDataXMLElement *item in items)
    {
        NSString *articleTitle = [item valueForChild:@"title"];
        NSString *articleUrl = [item valueForChild:@"link"];
        NSString *articleDateString = [item valueForChild:@"pubDate"];
    }
}

EDIT: XML LOOKS LIKE:

<item>
    <title>Your Direction Determines Your Destination</title>
    <link>http://treymorgan.podbean.com/2012/06/05/your-direction-determines-your-destination/</link>

        <enclosure url="http://treymorgan.podbean.com/mf/feed/x52488/DirectionDeterminesyourDestination.mp3" length="32015229" type="audio/mpeg"/>
</item>

This way I can get the title of the article from the Title tag within the XML. Most xmls I have parsed have included the mp3, either in the "guid" or "link" tag. However, the current feed I am working with, looks like this:

<enclosure url="http://treymorgan.podbean.com/mf/feed/bf8mvq/Accommoditions.mp3" length="29865594" type="audio/mpeg"/>

How can I pass the url from the enclosure into an NSString?

Answer 1

Something like [[item attributeForName: @"url"] stringValue] should do it. Depending on the actual location of the enclosure element in the XML tree, you might need to use another element instead of channel of course.

Answer is

[[[[item elementsForName: @"enclosure"] lastObject] attributeForName: @"url"] stringValue]
