Using dom4j to write XML files-source code

DOM4J Version: 2.1.1

To generate XML document steps using DOM4J:

1. Create a blank document for the Documents object.

2. Add the root element to the document, the element returned represents the root, and the XML document has only one root element.

3. Add child elements.

4. Create a XmlWriter object

5. Output Document Object
