Building a New DOM Document Object
This section provides a tutorial example on how to build a new DOM Document object and print it out as DOM Node tree.
DOM document objects can also be created from scratch instead of parsed from an XML file. This can be easily done by using the following methods:
The following program shows how to create a simple DOM document object with these methods:
/* DOMNewDoc.java - Copyright (c) 2002-2018 HerongYang.com. All Rights Reserved. */ import java.io.*; import javax.xml.parsers.*; import org.w3c.dom.*; class DOMNewDoc { public static void main(String[] args) { try { DocumentBuilderFactory f = DocumentBuilderFactory.newInstance(); DocumentBuilder b = f.newDocumentBuilder(); Document d = b.newDocument(); Element r = d.createElement("dictionary"); d.appendChild(r); Element w = d.createElement("word"); r.appendChild(w); Element e = d.createElement("update"); w.appendChild(e); e.setAttribute("date","2002-12-24"); e = d.createElement("name"); w.appendChild(e); e.setAttribute("is_acronym","true"); e.appendChild(d.createTextNode("DTD")); e = d.createElement("definition"); w.appendChild(e); e.appendChild(d.createTextNode("Document Type Definition")); printNode(d, ""); } catch (ParserConfigurationException e) { System.out.println(e.toString()); } } static void printNode(Node n, String p) { NodeList l = n.getChildNodes(); NamedNodeMap m = n.getAttributes(); int ml = -1; if (m!=null) ml = m.getLength(); System.out.println(p+n.getNodeName()+": "+n.getNodeType()+", " +l.getLength()+", "+ml+", "+n.getNodeValue()); for (int i=0; i<ml; i++) { Node c = m.item(i); printNode(c,p+" |-"); } for (int i=0; i<l.getLength(); i++) { Node c = l.item(i); printNode(c,p+" "); } } }
Run this sample Java program in JDK, you should get:
herong> java DOMNewDoc #document: 9, 1, -1, null dictionary: 1, 1, 0, null word: 1, 3, 0, null update: 1, 0, 1, null |-date: 2, 0, -1, 2002-12-24 name: 1, 1, 1, null |-is_acronym: 2, 0, -1, true #text: 3, 0, -1, DTD definition: 1, 1, 0, null #text: 3, 0, -1, Document Type Definition
