root = new Element("root");
Element e1 = new Element("child_level_1");
root.addContent(e1);
Element e2 = new Element("child_level_2");
e1.addContent(e2);
Element e3 = new Element("child_level_3");
e2.addContent(e3);
Element e4 = new Element("child_level_4");
e3.addContent(e4);
e4.setText("Data");

Element e11 = new Element("child_level_1");
root.addContent(e11);
Element e12 = new Element("child_level_2");
e11.addContent(e12);
Element e13 = new Element("child_level_3");
e12.addContent(e13);
Element e14 = new Element("child_level_4");
e13.addContent(e14);
