xml解析

首先是xml文档：

<types>
    <type id = "1">
        <name>name1</name>
    </type>
     <type id = "2">
        <name>name2</name>
    </type>
      <type id = "3">
        <name>name3</name>
    </type>
     <type id = "4">
        <name>name4</name>
    </type>
     <type id = "5">
        <name>name5</name>
    </type>
</types>

然后是解析的方法：

package com.example.spinnertest;

import java.util.ArrayList;
import java.util.List;

import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;
import org.w3c.dom.Document;
import org.w3c.dom.Element;
import org.w3c.dom.Node;
import org.w3c.dom.NodeList;

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

public class XMLManager {
    class Type{
        String id;
        String name;
        public Type(){
            
        }
        public String getId() {
            return id;
        }
        public void setId(String id) {
            this.id = id;
        }
        public String getName() {
            return name;
        }
        public void setName(String name) {
            this.name = name;
        }
        @Override
        public String toString() {
            // TODO Auto-generated method stub
            return name;
        }
        
    }
    public List<Type> start(Context context){
        Document doc = getDocumentFromXML(context,"types.xml");
        List<Type> result = null;
        if(doc!=null){
            result = new ArrayList<XMLManager.Type>();
            Element element = doc.getDocumentElement();  
            NodeList entry = element.getElementsByTagName("type");
            Type typeItem = null;
            for(int i=0;i<entry.getLength();i++){  
                typeItem = new Type();
                Element childElement = (Element) entry.item(i);
                typeItem.setId(childElement.getAttribute("id"));
                NodeList childNodes = childElement.getChildNodes();  
                for(int j=0;j<childNodes.getLength();j++){  
                    Node node = childNodes.item(j);
                    if(node.getNodeType()==Node.ELEMENT_NODE){  
                        if("name".equals(node.getNodeName())){ 
                            typeItem.setName(node.getTextContent());
                        }
                    }  
                } 
                result.add(typeItem);
            }
        }
        return result;
    }
    public static Document getDocumentFromXML(Context context,String xmlName){
        try {
            InputStream input = context.getResources().getAssets().open(xmlName);;
            DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();  
            DocumentBuilder builder;
            
                builder = factory.newDocumentBuilder();
            
            return builder.parse(input);  
        } catch (Exception e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } 
        return null;
    }
