you have to study about NSScanner

An similar example to your question.

NSString *src = nil;
NSString *newsRSSFeed = @"<p><a href=\"http://us.rd.yahoo.com/dailynews/rss/us/*http://news.yahoo.com/s/ap/20110521/ap_on_re_us/us_michelle_obama_west_point\"><img src=\"http://d.yimg.com/a/p/ap/20110520/capt.53a8af4c675f421c8b7cba014c589d29-53a8af4c675f421c8b7cba014c589d29-0.jpg?x=130&y=97&q=85&sig=iOyBvkyg0rEKSK3hjlSsNA--\" align=\"left\" height=\"97\" width=\"130\" alt=\"First lady Michelle Obama, left, and Lt.

    NSCharacterSet *charset = [NSCharacterSet characterSetWithCharactersInString:@"\"'"];
    [theScanner scanUpToCharactersFromSet:charset intoString:nil];
    [theScanner scanCharactersFromSet:charset intoString:nil];
    [theScanner scanUpToCharactersFromSet:charset intoString:&src];
