A new SelfSolved problem is ready for perusal:
A couple of my iPhone projects require a decent HTML/XHTML parser. On OS X, Cocoa ships with NSXMLDocument, which includes dirty HTML parsing functionality from libtidy. Unfortunately, NSXMLDocument is not part of the actual iPhone 2.2 SDK (though it is part of the 2.2 Simulator — so it’ll compile just fine at dev time but break when deploying — a big gotcha if you never tested against a real iPhone).
NSXMLParser is a part of the iPhone SDK…This is not a reasonable alternative.
Check out my writeup at SelfSolved #42: HTML or XHTML Parser for iPhone SDK 2.x
Finally, all out of all the potential alternatives I found (all referenced at the SelfSolved writeup — including one that requires a license fee to use), this one seems to be the most promising and requires the least amount of pain (read: interaction with the libxml C API — god knows I’ve done enough of that while building prototypes at Yahoo! Research Berkeley)
