通过内存，生成DOM树结构，简单，快适合于小文件

package com.Myproject.test;import java.io.*;import javax.xml.parsers.DocumentBuilder;import javax.xml.parsers.DocumentBuilderFactory;import javax.xml.parsers.ParserConfigurationException;import org.w3c.dom.Document;import org.w3c.dom.Node;import org.w3c.dom.NodeList;import org.xml.sax.SAXException;public class ZipFilenameFilter {    // DOM 生成和解析XML文档    public static void main(String[] args) {        File ff=new File("e:\\22.txt");        DocumentBuilderFactory dbf=DocumentBuilderFactory.newInstance();        try {            DocumentBuilder db=dbf.newDocumentBuilder();            Document doc=db.parse(ff);            NodeList weathers=doc.getElementsByTagName("Weather");            for (int i = 0; i < weathers.getLength(); i++) {                Node weather=weathers.item(i);                for (Node node=weather.getFirstChild(); node!=null; node=node.getNextSibling()) {                    if (node.getNodeType()==Node.ELEMENT_NODE) {                        System.out.println(node.getNodeName());                        if (node.getFirstChild()!=null) {                            System.out.println(node.getFirstChild().getNodeValue());                        }                    }                }            }        } catch (ParserConfigurationException e) {            // TODO Auto-generated catch block            e.printStackTrace();        } catch (SAXException e) {            // TODO Auto-generated catch block            e.printStackTrace();        } catch (IOException e) {            // TODO Auto-generated catch block            e.printStackTrace();        }    }}
