Answer 1

You can use NSScanner. Something like this:

NSString *src = nil;
NSString *newsRSSFeed = @"
AP - First lady Michelle Obama urged more than 1,000 cadets Friday night on the brink of graduating to keep in mind the families of the soldiers they will lead.

";
NSScanner *theScanner = [NSScanner scannerWithString:newsRSSFeed];
// find start of IMG tag
[theScanner scanUpToString:@" http://d.yimg.com/a/p/ap/20110520/capt.53a8af4c675f421c8b7cba014c589d29-53a8af4c675f421c8b7cba014c589d29-0.jpg?x=130&y=97&q=85&sig=iOyBvkyg0rEKSK3hjlSsNA--
