Java has
an API for working with the XML documents. By using this API you can
read the data from the XML document, create a new XML document, update
the XML document and even remove the existing nodes in the XML document.
You need to import certain package and classes to work with those API.
The most relevant imports that are to be done are,
_______________________________________________
import
org.w3c.dom.Document;
import org.w3c.dom.DOMException;
import org.w3c.dom.Element;
With these
imports in place you have to create a document object to work with the
XML document. This document object is created in three steps. The first
one is the creation of the DocumentBuilderFactory and then the creation
of the DocumentBuilder object. Then the final step is the creation of
the document object.
If you
want to create a new XML document you can do so by creating the elements
using the createElement() method. You could use the creatTextNode()
method to create the new text node and then use the appendChild() method
to append the child elements to the root node. Check the Java API for
the other classes and the methods that can be used to manipulate the
XML documents.
