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.
- Once the RSS data is retrieved from the server,…it's time to parse it.…Here I brought up a very simple RSS feed.…What this is, I created a little python script…on my server that generates an RSS feed,…I call it test feed.…It's at ios.bw.org/testfeed,…and you're welcome to use this for testing…for your applications.…And what it does, every time you load it,…it brings up random items.…So if you look at the individual items here,…there and the item containers here,…you have a title.…
This one says Add toner.…This one says Use other side for additional listings.…These are all just little random statements.…And so, if I press reload on my keyboard, command R,…you'll see that I get a different set each time,…there's As seen on TV.…Contestants have been briefed,…Penalty for private use.…Do not stamp.…Every time I press reload,…I get a different set of feeds,…and it gives five at a time.…But we can use this to look at what…a properly formed RSS feed looks like.…
RSS is an application of XML,…and so it has this XML header at the top of it.…
