How to verify the DOM (Document Object Model) implementation class information?
✍: FYIcenter
If you want to verify the DOM (Document Object Model) implementation class information, you can try the following example program:
// 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; public class DomClassInfo { public static void main(String[] args) throws Exception { DocumentBuilderFactory f = DocumentBuilderFactory.newInstance(); DocumentBuilder b = f.newDocumentBuilder(); Document d = b.newDocument(); Element e = d.createElement("Msg"); Text t = d.createTextNode("Hello World!"); e.appendChild(t); d.appendChild(e); System.out.println("DOM class info:"); System.out.println(" Factory: "+f.getClass().getName()); System.out.println(" Builder: "+b.getClass().getName()); System.out.println(" Document: "+d.getClass().getName()); System.out.println(" Element: "+e.getClass().getName()); System.out.println(" TextNode: "+t.getClass().getName()); } }
Compile and test it:
>\fyicenter\jdk-1.8.0\bin\javac DomClassInfo.java >\fyicenter\jdk-1.8.0\bin\java DomClassInfo DOM class info: Factory: com.sun.org.apache.xerces.internal.jaxp.DocumentBuilderFactoryImpl Builder: com.sun.org.apache.xerces.internal.jaxp.DocumentBuilderImpl Document: com.sun.org.apache.xerces.internal.dom.DocumentImpl Element: com.sun.org.apache.xerces.internal.dom.ElementImpl TextNode: com.sun.org.apache.xerces.internal.dom.TextImpl
The output tells you that the default implementation of DOM in Java SE 8 JDK is the Apache Xerces package.
⇒ Version of Apache Xerces Used in Java SE 8
⇐ Using XML DOM API with Apache Xerces
