Getting Substring with NSRange

Question

I try to read out the url's of youtubevideos from this link: http://gdata.youtube.com/feeds/api/videos?author=channelname

I tried it like this:

NSRange startRange = [ret rangeOfString:@"<media:content url='http"];
NSRange endRange = [ret rangeOfString:@"'"];

NSRange searchRange = NSMakeRange(startRange.location , endRange.location);
NSLog(@"Link: %@",[ret substringWithRange:searchRange]);

The output is just: <media:content

Where is my mistake?

Can you put up original string ? I mean value of ret – Abhishek Dec 31 '13 at 10:11 — Abhishek, Dec 31 '13 at 10:11

The mistake is that you're not using the right tool for the task.

Anyways, you seem to be confusing the length and the ending location of ranges. NSMakeRange() takes a location and a length, not the starting and the ending location.

Also, don't expect - [NSString rangeOfString:] to magically guess what you are trying to do. It will return the first occurrence of the given substring, and here that is not what you want.
