Java preg_match array

Question

Have string strng = "<title>text1</title><title>text2</title>"; How to get array like

arr[0] = "text1";
arr[1] = "text2";

I try to use this, but in result have, and not array text1</title><title>text2

Pattern pattern = Pattern.compile("<title>(.*)</title>");
Matcher matcher = pattern.matcher(strng);
matcher.matches();

Answer 1

While I agree that using an XML / HTML parser is a better alternative in general, your scenario is simple to solve with regex:

List<String> titles = new ArrayList<String>();
Matcher matcher = Pattern.compile("<title>(.*?)</title>").matcher(strng);
while(matcher.find()){
    titles.add(matcher.group(1));
}

Note the non-greedy operator .*? and use of matcher.find() instead of matcher.matches().

• Matcher.find()
