How to build an XML document tree with the DOM API?
✍: FYIcenter
If you want to build an XML document tree with the DOM (Document Object Model) API, you can follow these suggestions:
1. Use the factory class to create DocumentBuilder object:
DocumentBuilderFactory f = DocumentBuilderFactory.newInstance(); DocumentBuilder b = f.newDocumentBuilder();
2. Call the newDocument() method on the DocumentBuilder object to create a new Document object:
Document d = b.newDocument(); System.out.println("Implementation class:\n "+d.getClass().getName());
3. Call the createElement() method on the Document object to create a new Element object. Then add it to the Document as the root element:
Element e = d.createElement("User"); d.appendChild(e);
3. Call the createElement() method on the Document object repeatedly to create new Element objects. Then add them to parent elements to build the XML document tree:
Element c = d.createElement("ID"); c.appendChild(d.createTextNode("202")); e.appendChild(c);
Here is a complete example of parsing an XML file with DOM API, DomXmlParser.java:
// Copyright (c) 2017 FYIcenter.com import javax.xml.parsers.DocumentBuilderFactory; import javax.xml.parsers.DocumentBuilder; import org.w3c.dom.Document; import org.w3c.dom.Element; import org.w3c.dom.Text; import org.w3c.dom.Node; import org.w3c.dom.NodeList; public class DomDocumentTree { static String dot = "............................................................"; public static void main(String[] args) throws Exception { DocumentBuilderFactory f = DocumentBuilderFactory.newInstance(); DocumentBuilder b = f.newDocumentBuilder(); Document d = b.newDocument(); System.out.println("Implementation class:\n "+d.getClass().getName()); Element e = d.createElement("User"); d.appendChild(e); Element c = d.createElement("ID"); c.appendChild(d.createTextNode("202")); e.appendChild(c); c = d.createElement("Name"); c.appendChild(d.createTextNode("Frank Y. Ivy")); e.appendChild(c); c = d.createElement("BirthDate"); c.appendChild(d.createTextNode("1970-01-01")); e.appendChild(c); System.out.println("DOM object elements and text contents:"); Node n = d.getDocumentElement(); printText(n, 1); } public static void printText(Node n, int l) { String v = ""; if (n.getNodeType()==Node.TEXT_NODE) v = n.getTextContent(); System.out.println(dot.substring(0,l)+n.getNodeName()+":"+v); NodeList c = n.getChildNodes(); for (int i=0; i<c.getLength(); i++) { printText(c.item(i),l+1); } } }
Compile and run the example program, DomDocumentTree.java:
>\fyicenter\jdk-1.8.0\bin\javac DomDocumentTree.java >\fyicenter\jdk-1.8.0\bin\java DomDocumentTree Implementation class: com.sun.org.apache.xerces.internal.dom.DocumentImpl DOM object elements and text contents: .User: ..ID: ...#text:202 ..Name: ...#text:Frank Y. Ivy ..BirthDate: ...#text:1970-01-01
