Java and XML (ii) write XML reading and writing programs in Java

This is to read the XML file Java program, I debug good. The DOM method is used to read the XML file into the vector.

Package src;
Import java.io.*;
Import Java.util.Vector;
Import javax.xml.parsers.*;
Import org.w3c.dom.*;
public class ReadXml {
static document document;
private Boolean validating;
Public ReadXml () {
}
Public Vector toread (String filename) {
Vector title=new vector ();
Vector content=new vector ();
String Mystr=new string ();
try {
Documentbuilderfactory factory = Documentbuilderfactory.newinstance ();
Factory.setvalidating (validating);
Documentbuilder builder = Factory.newdocumentbuilder ();
Document = Builder.parse (new File (filename));
Document.getdocumentelement (). normalize ();
Node node = Document.getfirstchild ();
NodeList list = Node.getchildnodes ();
for (int i = 0; i < list.getlength (); i++) {
Node nodeitm = List.item (i);
if (Nodeitm.getnodename (). Equals ("Title")) {
Mystr=nodeitm.getfirstchild (). Getnodevalue ();
Title.addelement (MYSTR);//getfirstchild ()
}
if (Nodeitm.getnodename (). Equals ("Content")) {
Mystr=nodeitm.getfirstchild (). Getnodevalue ();
Content.addelement (MYSTR);
}
}
catch (Exception exp) {
Exp.printstacktrace ();
return null;
}
Vector all=new vector ();
All.add (title);
All.add (content);
return all;
}

public static void Main (string[] args) {
Vector A;
ReadXml my = new ReadXml ();
A = My.toread ("F:\\tomcat5\\webapps\\myxml\\xmldata\\9.xml");
for (int i = 0; i < a.size (); i++) {
System.out.println (A.elementat (i));
}
}
}
