dom4j+xpath解析带有属性的xml文档

server.xml

<?xml version="1.0" encoding="utf-8"?>
<server>
    <service>
        <connector port ="8080"></connector>
    </service>
</server>

package edu.aeon.xml;

import org.dom4j.Attribute;
import org.dom4j.Document;
import org.dom4j.DocumentException;
import org.dom4j.Element;
import org.dom4j.io.SAXReader;

/**
 * [说明]:通过dom4j+xpath获取节点属性的值
 *     需要导入dom4j和xpath的jar包

public class Dom4jXpathAttri {

    public static void main(String[] args) {
        try {
            SAXReader saxReader=new SAXReader();
            Document document=saxReader.read("config/server.xml");
            Element connectorElement = (Element) document.selectSingleNode("/server/service/connector");
            //2种方式任选一种即可
            Attribute attribute = connectorElement.attribute("port");
            String attributeValue1=attribute.getStringValue();
            String attributeValue2 = connectorElement.attributeValue("port");
            System.out.println(attributeValue1+"\t"+attributeValue2);
        } catch (DocumentException e) {
            e.printStackTrace();
        }
    }
}
