Search for a string between two known strings

Question

I have a String with this content:

href=\"http://www.website.com/\" /> [...] [...]

I just want to get the central part of the string. Ho

Answer 1

I got it!

This is the code (not very nice written):

NSRange rr2 = [content rangeOfString:@"href=\""];
    NSRange rr3 = [content rangeOfString:@"\" />"];
    int lengt = rr3.location - rr2.location - rr2.length;
    int location = rr2.location + rr2.length;
    NSRange aa;
    aa.location = location;
    aa.length = lengt;
    theString = [theString substringWithRange:aa];

Answer 2

This can be done more compactly:

NSRange end = [source rangeOfString:@"\" />"];
if (end.location != NSNotFound) {
    result = [source substringWithRange:NSMakeRange(6, end.location - 6)];
}

Answer 3

How about

NSString* newNSString =[[[theString substringFromIndex:6] componentsSeparatedByString:@"/\""]objectAtIndex:0];

Or

NSString* newNSString =[[[[theString componentsSeparatedByString:@"href=\""]objectAtIndex:1] componentsSeparatedByString:@"/\""]objectAtIndex:0];
