InnerHTML for Java

Question

I would like JavaScript style innerHTML in Java. For instance, I want to get 'TRUE' from the string below:

String control = "<div class='myclass'>TRUE</div>";

But my pattern seems to be off as find() returns false. Ideas anyone?

Pattern pattern = Pattern.compile(">(.*?)<");
Matcher matcher = pattern.matcher(control);

if(matcher.find()) {
    result = matcher.group(1);
}

Why not use jquery to do this or at least some dom selector rather than regexes? — Jeff Storey, Dec 20 '13 at 00:37

get rid of the question mark:

public static void main(String[] args) {
    String control = "<div class='myclass'>TRUE</div>";
    Pattern pattern = Pattern.compile(">(.*)<");
    Matcher matcher = pattern.matcher(control);
    String result = null;
    if(matcher.find()) {
        result = matcher.group(1);
    }
    System.out.print(result);
}

BTW it would be better to learn how to use java's DOM objects and XPath classes.

Your BTW is the really the only way of doing it. – Shafiq Jetha Dec 20 '13 at 00:43
System.out.print(control.replaceAll("<[^>]*>", "")); – msknapp Dec 20 '13 at 00:46
This is exactly what I need. DOM and XPath are too heavyweight. I'm not working with fully formed documents but rather snippets from a WCMS. The expected String 'should' never have nested tags. @Jeff Storey jquery is also out as this process occurs in a pre-rendering state on the server. Thanks everyone. – TheRed__ Dec 20 '13 at 12:58

Either use Jquery or if you really insist on doing it in Java, try using JSoup to strip out the HTML and return on the safe stuff
