Sample code on how to read an XML file in java

Classes and methods to read an XML file and to manipulate an XML file is available in java. With these APIs you can do anything with an XML file. To work with an XML file you have to do the following imports.

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

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

The above code gives you an idea on how to create a document object to load the XML file you want and then work on it. you have to create objects like DocumentBuilderFactory, DocumentBuilder, and then Document to work on an XML file.

The XML file is loaded in the Document object. A NodeList object is created and then the elements of the XML file are loaded in it. Using a 'for' loop all the elements are displayed. Methods to change and remove the nodes are also available.
