    why not just use `DOM` + `xpath` instead – Kevin Jun 23 '16 at 00:15

    You shall not use regexes to parse HTML, see this: http://stackoverflow.com/questions/1732348/regex-match-open-tags-except-xhtml-self-contained-tags/1732454#1732454 . You can parse a limited set of HTML with regexes: for example, if you first insert a new line before every occurrence of `href` then you have a specially formatted HTML which should be easier to parse by regexes. – grochmal Jun 23 '16 at 00:16
  • @Ghost Maybe because I do not know how i used DOM – omar dealo Jun 23 '16 at 00:20
