Better might be to use an HTML parser (or something like HTML::LinkExtor) and simplify what you have to look at.	[reply]

`(?:(?<!video).)+` is wrong. `for my $re ( qr/"(?:(?!video).)+"/, qr/"(?:(?<!video).)+"/, qr/"(?:.(?<!video))+"/, ) { print("$re\n"); for ( '"...video..."', '"...video"', '"video..."', '"video"', ) { print("$_: ", /$re/?1:0, "\n"); } }` [download] `(?-xism:"(?:(?!video).)+") "...video...": 0 "...video": 0 "video...": 0 "video": 0 (?-xism:"(?:(?<!video).)+") "...video...": 0 "...video": 1 <----- XXX "video...": 0 "video": 1 <----- XXX (?-xism:"(?:.(?<!video))+") "...video...": 0 "...video": 0 "video...": 0 "video": 0` [download] `(?:(?!video).)+` and `(?:.(?<!video))+` should be equivalent. You can do benchmarks to be sure.	[reply] [d/l] [select]
