java dom解析XML

有人要java dom解析的XML通讯录 洒家给写了个

用swing做的  解析XML那部分代码：

 

package com.test.parseXML;
import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;
import javax.xml.parsers.ParserConfigurationException;
import javax.xml.transform.Transformer;
import javax.xml.transform.TransformerConfigurationException;
import javax.xml.transform.TransformerException;
import javax.xml.transform.TransformerFactory;
import javax.xml.transform.dom.DOMSource;
import javax.xml.transform.stream.StreamResult;

import java.awt.List;
import java.io.*;
import java.util.ArrayList;
import java.util.Vector;

import org.w3c.dom.Document;
import org.w3c.dom.Element;
import org.w3c.dom.Node;
import org.w3c.dom.NodeList;
import org.w3c.dom.Text;
import org.xml.sax.SAXException;

public class ParseXML {
	
	private Document getDocument(String filename)
	{
		DocumentBuilderFactory factory=DocumentBuilderFactory.newInstance();
		factory.setIgnoringElementContentWhitespace(true);
		try {
			DocumentBuilder domParser=factory.newDocumentBuilder();
			try {
				Document document=domParser.parse(new File(filename));
				return document;
			} catch (SAXException e) {
				e.printStackTrace();
			} catch (IOException e) {
				e.printStackTrace();
			}
		} catch (ParserConfigurationException e) {
			e.printStackTrace();
		}
		return null;
	}
	
	public ArrayList<ArrayList> getNodeInfo(String filename)
	{
		ArrayList<ArrayList> myli=new ArrayList<ArrayList>();
		Document document=getDocument(filename);
		NodeList nodelist=document.getElementsByTagName("anpai");
		for(int i=0;i<nodelist.getLength();i++)
		{
			String date=document.getElementsByTagName("date").item(i).getTextContent();
			String time=document.getElementsByTagName("time").item(i).getTextContent();
			String activity=document.getElementsByTagName("activity").item(i).getTextContent();
			ArrayList<String> li=new ArrayList<String>();
			li.add(date);
			li.add(time);
			li.add(activity);
			myli.add(li);
		}
		return myli;
	}
	
	public ArrayList<ArrayList> getQueryNodeInfo(String filename,String query_date)
	{
		ArrayList<ArrayList> myli=new ArrayList<ArrayList>();
		Document document=getDocument(filename);
		NodeList nodelist=document.getElementsByTagName("anpai");
		for(int i=0;i<nodelist.getLength();i++)
		{
			String date=document.getElementsByTagName("date").item(i).getTextContent();
			if(date.equals(query_date))
			{
			String time=document.getElementsByTagName("time").item(i).getTextContent();
			String activity=document.getElementsByTagName("activity").item(i).getTextContent();
			ArrayList<String> li=new ArrayList<String>();
			li.add(date);
			li.add(time);
			li.add(activity);
			myli.add(li);
			}
		}
		return myli;
	}
	
	public void deleteNode(String filename,int rowCount)
	{
		Document document=getDocument(filename);
		NodeList nodelist=document.getElementsByTagName("anpai");
		Node anpai_node=nodelist.item(rowCount);//anpai节点
		anpai_node.getParentNode().removeChild(anpai_node);
		updateXML(filename,document);
	}
	
	public void addNode(String filename,String date_str,String time_str,String activity_str)
	{
		Document document=getDocument(filename);
		Node node=document.createElement("anpai");
		Node node_child1=document.createElement("date");
		Node node_child2=document.createElement("time");
		Node node_child3=document.createElement("activity");
		Text textnode_date=document.createTextNode(date_str);

		node.appendChild(node_child2);
		node.appendChild(node_child3);
		document.getDocumentElement().appendChild(node);
		updateXML("src/schedule.xml",document);
	}
	
	public String[] getNodeInfoByRow(String filename,int rowcount)
	{
		Document document=getDocument(filename);
		String date=document.getElementsByTagName("date").item(rowcount).getTextContent();
		String time=document.getElementsByTagName("time").item(rowcount).getTextContent();
		String activity=document.getElementsByTagName("activity").item(rowcount).getTextContent();
		String []arr={date,time,activity};
		return arr;
	}
	
	public void editNode(String filename,int whichnode,String e_date,String e_time,String e_activity)
	{
		Document document=getDocument(filename);
		//System.out.println(document.getElementsByTagName("date").item(whichnode).getChildNodes().item(0).getNodeValue());
		document.getElementsByTagName("date").item(whichnode).getChildNodes().item(0).setNodeValue(e_date);
		document.getElementsByTagName("time").item(whichnode).getChildNodes().item(0).setNodeValue(e_time);
		document.getElementsByTagName("activity").item(whichnode).getChildNodes().item(0).setNodeValue(e_activity);
		updateXML(filename,document);
	}
	
	public void updateXML(String filename,Document document)
	{
		TransformerFactory tfactory=TransformerFactory.newInstance();
		try {
			Transformer transformer=tfactory.newTransformer();
			DOMSource domsource=new DOMSource(document);
			StreamResult result = new StreamResult(new File(filename));
			try {
				transformer.transform(domsource,result);
			} catch (TransformerException e) {
				e.printStackTrace();
			} 
		} catch (TransformerConfigurationException e) {
			e.printStackTrace();
		}
	}

}

继承AbstractTableModel:

package com.test.model;

import java.util.ArrayList;
import java.util.Vector;

import javax.swing.table.AbstractTableModel;

import org.w3c.dom.Node;
import org.w3c.dom.NodeList;

import com.test.parseXML.ParseXML;

public class ScheModel extends AbstractTableModel{
	
	private Vector columnNames;
	private Vector rowData;
	
	public ScheModel()
	{
		init("");
	}
	public ScheModel(String date)
	{
		init(date);
	}

	public void init(String date)
	{
		
		rowData=new Vector();
		columnNames=new Vector();
		columnNames.add("日期");
		columnNames.add("时间");
		columnNames.add("事件");
		if(date=="")
		{
		ParseXML parse=new ParseXML();
		ArrayList<ArrayList> al=parse.getNodeInfo("src/schedule.xml");
		for(int i=0;i<al.size();i++)
		{
			ArrayList<String> a=al.get(i);
			Vector hang=new Vector();
			for(int j=0;j<a.size();j++)
			{
				hang.add(a.get(j));
			}
			rowData.add(hang);
		}
		}
		else
		{
			ParseXML parse=new ParseXML();
			ArrayList<ArrayList> al=parse.getQueryNodeInfo("src/schedule.xml",date);
			for(int i=0;i<al.size();i++)
			{
				ArrayList<String> a=al.get(i);
				Vector hang=new Vector();
				for(int j=0;j<a.size();j++)
				{
					hang.add(a.get(j));
				}
				rowData.add(hang);
			}
		}
		
	}
	@Override
	public int getColumnCount() {
		return columnNames.size();
	}

	@Override
	public int getRowCount() {
		return rowData.size();
	}

	@Override
	public Object getValueAt(int arg0, int arg1) {
		return ((Vector) rowData.get(arg0)).get(arg1);
	}

	@Override
	public String getColumnName(int arg0) {
		return (String) columnNames.get(arg0);
	}
	
	

}

 

用Castor和JavaBean，你这些代码都可以省略掉
