Java class that parses Shoutcast stats XML

I have written a Java class that parses Shoutcast 2 stats XML. It uses JDOM to parse the XML. I have only basic knowledge of Java and I wrote this class in about 3 hours. It works, but I don't know if I've done everything right, or how efficient it is. I intend to use this class in an Android app I am working on. You can view the class below. Any feedback to make this class better and more efficient is greatly appreciated.

package com.brandsonic.shoutcastParser;

import org.jdom2.Element;
import org.jdom2.JDOMException;
