This answer is for google searchers, Because it's too late

Copying cletus's showed error and Modifying his answer and passing modified String src\\s*=\\s*([\"'])?([^\"']*) as parameter passed into Pattern.compile worked for me,

Here is the full example

    String htmlString = "
"; //Sample HTML

    String ptr= "src\\s*=\\s*([\"'])?([^\"']*)";
    Pattern p = Pattern.compile(ptr);
    Matcher m = p.matcher(htmlString);
    if (m.find()) {
        String src = m.group(2); //Result
    }
