从XML文件和properties文件提取数据

XML文档格式内容如下

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

<root>

    <field type="1" store="yes">title1</field>

    <field type="2" store="no">title2</field>

    <field type="3" store="yes">title3</field>

</root>

JAVA代码如下

import java.io.File;

import java.io.IOException;

 

import javax.xml.parsers.DocumentBuilder;

import javax.xml.parsers.DocumentBuilderFactory;

import javax.xml.parsers.ParserConfigurationException;

 

import org.w3c.dom.Document;

import org.w3c.dom.NodeList;

import org.xml.sax.SAXException;

 

public class MyXml {

    public static void main(String[] args) throws ParserConfigurationException, SAXException, IOException {

        //读取XML文件

        File f = new File("E:\\workspace\\cn.harmel.lucene\\src\\1.xml");

        //获取DocumentBuilderFactory

        DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();

        //通过DocumentBuilder工厂产生一个DocumentBuilder

        DocumentBuilder builder = factory.newDocumentBuilder();

        //利用DocumentBuilder产生Document

        Document doc = builder.parse(f);

        //获取指定的标签的集合

        NodeList nl = doc.getElementsByTagName("field");

        for (int i = 0; i < nl.getLength(); i++) {

           String fieldName=nl.item(i).getFirstChild().getNodeValue();//获取标签值

           String fieldType=nl.item(i).getAttributes().getNamedItem("type").getNodeValue();//获取标签属性值

           String fieldStore=nl.item(i).getAttributes().getNamedItem("store").getNodeValue();//获取标签属性值

           System.out.println(fieldName+"------"+fieldType+"------"+fieldStore);

        }       

    }

}
