How to parse a String containing XML in Java and retrieve the value of the root node?

Question

I have XML in the form of a String that contains

HELLO! 

How can I get the String \"Hello!\" from the XML?

Answer 1

There is doing XML reading right, or doing the dodgy just to get by. Doing it right would be using proper document parsing.

Or... dodgy would be using custom text parsing with either wisuzu's response or using regular expressions with matchers.
