Dom解析xml，测试demo

DomParseXml.java （在activity的onCreate等方法中执行parseXml方法运行即可）

package com.example.androidtest;

import java.io.IOException;
import java.io.InputStream;
import java.util.ArrayList;

import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;
import javax.xml.parsers.ParserConfigurationException;

import org.w3c.dom.NodeList;
import org.xml.sax.Attributes;
import org.xml.sax.SAXException;

import android.content.Context;
import android.util.Log;

public class DomParseXml {
	public static final String LOG_TAG = "DomParseXml";
	
	private static final String sTag1 = "test_item";
	private static final String sTag2 = "test_folder";
	
	private static ArrayList<String> sAll = new ArrayList<String>();
	
	public static void parseXml(Context context){
		DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
		
		try {
			DocumentBuilder builder = factory.newDocumentBuilder();
			
//获取InputStream的两种方式
//			InputStream in = context.getResources().openRawResource(R.raw.test_config);

				String tagName = element.getNodeName();
				Log.d(LOG_TAG, "tag name is:"+tagName);

					continue;
				}
				String text = element.getTextContent();
				Log.d(LOG_TAG, "text is:"+text);

				}
				temp.append("--");
				temp.append(text);
				
				sAll.add(temp.toString());
			}
			
		} catch (ParserConfigurationException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} catch (IOException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} catch (SAXException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
		
		//-------打印
		for(String s:sAll){

		}

}

xml文件   test_config1.xml

<?xml version="1.0" encoding="utf-8"?>

<test_config version="1">
    <test_item item_name="item1">你们</test_item>
    <test_item item_name="item2">是</test_item>
    <test_folder folder_name="folder1">好</test_folder>
    <test_folder folder_name="folder2">孩子</test_folder>
</test_config>

测试结果：

D/DomParseXml(11085): Dom parse is:test_item--item_name--item1--你们
D/DomParseXml(11085): Dom parse is:test_item--item_name--item2--是
D/DomParseXml(11085): Dom parse is:test_folder--folder_name--folder1--好
D/DomParseXml(11085): Dom parse is:test_folder--folder_name--folder2--孩子
