Join Bill Weinman for an in-depth discussion in this video Parsing the feed with NSXMLParser, part of iOS SDK and SQLite: Building Data-Driven Apps.
- Now that we have an RSS feed, we need to run NSXMLParser…to get the title and description of the feed.…This will be stored in the database…and used for displaying in the main feed table view.…In this movie, we'll concentrate…on parsing the feed to get these pieces of data.…Here I have opened a working copy of BWRSS-AddView-03…from chapter five of the Exercise Files.…And if we look at, or is it here,…parseRSSHeader(),…this gets called when we know…that we have data that is an RSS feed.…
We set up an NSXMLParser object called parser.…Set the delegate to self and call parse.…Now we get our data in the NSXMLParserDelegate.…And these delegate methods are…just like we saw in the items table view.…Yeah, what we're doing with it is…actually quite a big simpler.…All we're looking for,…and if we take a look here at our sample RSS feed,…all we're looking for is these items here:…the title, the link, and the description.…
So here in parserDidStartDocument,…we set up the data structures for parsing.…And you notice this little status message here.…
