java实现简单解析XML文件功能示例
本文实例讲述了java实现简单解析XML文件功能。分享给大家供大家参考,具体如下:
package demo;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.Element;
import org.w3c.dom.NodeList;
import org.xml.sax.SAXException;
public class JieXiXML {
public static void main(String[] args) throws ParserConfigurationException, SAXException, IOException {
DocumentBuilderFactory bdf = DocumentBuilderFactory.newInstance();
DocumentBuilder db = bdf.newDocumentBuilder();
Document document = db.parse(new File("user.xml"));
NodeList list = document.getElementsByTagName("usa");
System.out.println("测试结果:");
for (int i = 0; i < list.getLength(); i++) {
Element element = (Element)list.item(i);
String name = element.getElementsByTagName("name").item(0).getFirstChild().getNodeValue();
System.out.println(name);
String pass = element.getElementsByTagName("pass").item(0).getFirstChild().getNodeValue();
System.out.println(pass);
System.out.println("------------------");
}
}
}
xml文件user.xml的内容:
<?xml version="1.0" encoding="UTF-8"?><user>
<usa>
<name>张三</name>
<pass>张三的密码</pass>
</usa>
<usa>
<name>里斯</name>
<pass>里斯的密码</pass>
</usa>
</user>
运行结果:
