Ono

Ono is a sensible way to deal with XML & HTML for iOS & Mac OS X.

XML support in Cocoa isn’t great (unless, of course, the XML in question is a .plist). NSXMLParser forces a cumbersome delegate model, which is extremely inconvenient to implement. NSXMLDocument is a bit nicer to use, but only works on Mac OS X, and has a large memory footprint.

Ono makes working with XML & HTML as nice as JSON.

Whether your app needs to interface with a XML-RPC webservice, scrape a website, or parse an RSS feed, Ono will make your day a whole lot less terrible.
