Question

Could you help me to make RegExp? In large string I need to find these substrings(2 formats):

http://www.facebook.com/profile.php?id=100002234024152&ref=ffa\
http://www.facebook.com/alesya.yuldasheva?ref=ffa\

I tried these:

@"\\b(https?):\/\/www.facebook.com([.]{*})ref=ffa";
@"[{http:\/\/www.facebook.com}([.]{*}){ref=ffa}]";
@"[http:\/\/www.facebook.com]([.])*[ref=ffa]";

I use RegexKitLite, which syntax same as normal objective c regular expressions.

NSError *error = nil;
NSString *htmlAdr = [NSString stringWithContentsOfURL:[NSURL URLWithString:@"http://www.example.com"] encoding:NSUTF8StringEncoding error:&error];
if (error){
    NSLog(@"Yaz");
}
 // NSLog(@"%@", htmlAdr);
NSString *wereWeAreGoingToFind = htmlAdr;
NSString *whatWewAreGoingToFind1 = @"\\bhttps?:\\\\/\\\\/[a-zA-Z0-9\\-.]*\\\\/profile.php\\?id=([\\d]*)\\&ref=ffa";
NSString *whatWewAreGoingToFind = @"\\bhttps?:\\\\/\\\\/[a-zA-Z0-9\\-.]*\\\\/([a-zA-Z0-9\\-.]*)\\?ref=pb";
NSArray *matchArray = [wereWeAreGoingToFind componentsMatchedByRegex:whatWewAreGoingToFind capture:1L];
NSArray *matchArray1 = [wereWeAreGoingToFind componentsMatchedByRegex:whatWewAreGoingToFind1 capture:1L];
matchArray = [matchArray arrayByAddingObjectsFromArray:matchArray1];
NSLog(@"%@", matchArray);
