To work
with the XML document in Java, you have to create a document object
in which you can load the XML file. To create the document object you
have to use the classes.
_______________________________________________
DocumentBuilderFactory
and the DocumentBuilder. The import statement at the top would contain,
import
org.w3c.dom.Document;
import org.w3c.dom.*;
import javax.xml.parsers.DocumentBuilderFactory;
import javax.xml.parsers.DocumentBuilder;
which are
mandatory.
Now, you
can create DocumentBuilderFactory object and then use this object's
newDocumentBuilder() method to create the DocumentBuilder object. With
this DocumentBuilder object you can create a Document object that can
be used to load the XML file that you want to use in your Java programming.
After you
have loaded the XML document, you can create a node list by using the
getElementByTagName() method of the document object. This would give
an array and this can be stored in a NodeList object and then can be
looped using "for" loop to print out the elements in the format
you want.
