FileInputStream fis = new FileInputStream(file); //where file holds the data to parse. 

Can also use StringBuilder
SAXBuilder builder = new SAXBuilder();
Document doc = builder.build(fis); //build a JDOM doc from file
ArrayList<String> arl = new ArrayList<String>();
Element root = doc.getRootElement();
Iterator elemIter = root.getDescendants(); //you can put filters on this to only get specific types of elements ie: root.getDescendants("ZQuery"); will give you an iterator over just ZQuery elements. 

while (elemIter.hasNext()) {
  Element foo = (Element) elemIter.next();
  String CDATA = foo.getChildText("ZQuery")
  arl.add(CDATA);
}
