Java regular expression to retrieve data between tags

Question

I am trying to use a regular expression that outputs data from a string like

<B Att="text">Test</B><C>Test1</C>

The output selected should be Test and Test1. This is what I have done so far:

public class HelloWorld {
    public static void main(String[] args)
    {
        String s = "<B>Test</B>";
        String reg = "<.*?>(.*)<\\/.*?>";
        Pattern p = Pattern.compile(reg);
        Matcher m = p.matcher(s);
        while(m.find())
        {
            String s1 = m.group();
            System.out.println(s1);
        }
    }
}

But this leads to a result <B>Test</B>. Can someone point out what I'm doing wrong?

Answer 1

Three problems:

• Your test string is incorrect.
• You need an inanimate modifier in a group.
• You need to specify which group you want (group 1).

Try the following:

String s = "<B Att=\"text\">Test</B><C>Test1</C>"; // <-- Fix 1
String reg = "<.*?>(.*?)</.*?>";                   // <-- Fix 2
// ...
String s1 = m.group(1);                            // <-- Fix 3

You also don't need to avoid the slash, so I removed this.
