Sample java code on how to read XML file

There are APIs for reading an XML file and displaying them. There are certain packages that you have to import before you do such a program. The following is a simple listing template that gives you information on how to create a document object and then load the XML file in it to process it.

import org.w3c.dom.Document;
import org.w3c.dom.DOMException;
import org.w3c.dom.Element;

DocumentBuilderFactory dbfact = DocumentBuilderFactory.newInstance();
DocumentBuilder dbuild = dbfact.newDocumentBuilder();
Document dc = dbuild.parse (new File("xml_file.xml"));
. . .
. . .
doc.getDocumentElement().getNodeName());
NodeList nlist = dc.getElementsByTagName("ele_name");
. . .
. . .

The import statements on the top gives you access to the classes and the methods that are used in reading an XML file. To create a document object a DocumentBuilderFactory object is first created and then a DocumentBuilder object is created.

With this DocumentBuilder you can create a Document object and load it with the XML file you need to process. Then a node list is created and the elements are loaded in it. This node list is looped by using a 'for' loop and worked upon.
