Question

I have a NSString that contains the html code of a webpage.
Now, how do i search on the whole string for all the words that start with ‘data-src=”http://’ and end with a ” ?
I’ll save them in an array.
My string is called urlPage

PS: i dont want the words to have the ‘data-src=”http://’ and ” . I just want the words between these 2

Here is some example code:

NSString *string;
NSString *pattern;
NSRegularExpression *regex;

string = @" aa data-src=\"http://test1\" cd data-src=\"http://test2\" cd";
pattern = @"data-src=\"http://([^\"]+)\"";

regex = [NSRegularExpression
         regularExpressionWithPattern:pattern
         options:NSRegularExpressionCaseInsensitive
         error:nil];

NSArray *matches = [regex matchesInString:string
                                  options:0
                                    range:NSMakeRange(0, [string length])];

for (NSTextCheckingResult *match in matches) {
    NSRange range = [match rangeAtIndex:1];
    NSLog(@"match: '%@'", [string substringWithRange:range]);
}

NSLog output:
match: ‘test1’
match: ‘test2’
