下面是我调用的一个类，我套用了一般的DOM处理XML文档的方法，制作了相应的改动。
package sql;
import org.w3c.dom.*;
import org.apache.xerces.parsers.DOMParser;
import java.io.*;
public class UpsInforParser
{
	private String[] displayStrings = new String[5000];
	private String[] value = new String[5000];
	private int numberDisplayLines = 0;
	private Node  c;
	private Document doc;
	private  String[] str;
	private int k = 0;
 	private String index;
	public UpsInforParser(String[] data)
	{
		this.str = data;
	}
	public UpsInforParser()
	{
	}	
	public static void main(String[] args)
	{
		String[] s = {"tNAME","tIP","ZONE","POSITION","CODE"};
		UpsInforParser parser = new UpsInforParser(s);
//		parser.createDoc("data/upsinfor.xml");
		//for(int loopIndex = 0;loopIndex < numberDisplayLines;loopIndex++)
		//{
			//System.out.println(displayStrings[loopIndex]);
