9.4：Java：xml操作實例 · Java自動化測試

首先創建 **.xml** 文件，內容如下； ``` <?xml version="1.0" encoding="utf-8" ?>  <stus> <stu id="18"> <name>我是xml</name> <age>20</age> <address>Beijing</address> </stu> <stu id="12"> <name>我是xml的滴滴</name> <age>19</age> <address>ShangHai</address>       </stu> <stu id="13"> <name>I`m jack</name> <age>24</age> <address>Tianjin</address> </stu> </stus> ``` 我們要獲取每個stu里面的元素內容，節點開始是`<stus>` 終點是`</stus>` 首先要獲取一個操作解析xml文件的對象，其次通過對象獲取到獲取到方法類，然后通過方法類獲取到起點標簽，然后.....以此類推 **代碼實現：** ``` package day05; import org.apache.log4j.Logger; import org.dom4j.Document; import org.dom4j.Element; import org.dom4j.io.SAXReader; import java.io.File; import java.util.List; public class day01xmlmathch { //Logger.getLogger(Tester.class)，根據log4j.properties文件的配置去創建一個Tester類（當前類的字節碼對象）的日志對象 private static Logger logger = Logger.getLogger(day01xmlmathch.class); public static void main(String args[]) throws Exception { String xmlpath = "src/day05/day01xml.xml"; parsingxml(xmlpath); } // throws是主動拋出異常 public static void parsingxml(String xmlpath) throws Exception { // 獲得SaxReader解析器對象 SAXReader saxread = new SAXReader(); // 獲得document對象 // 這里的Document用的是org.dom4j里面的 Document document = saxread.read(new File(xmlpath)); // 獲得根元素 Element Elementroot = document.getRootElement(); // 獲得根元素下的子元素 List<Element> elemlists = Elementroot.elements("stu"); // elements返回的是一個list集合 int num = 0; for(Element element : elemlists){ num++; System.out.println("Processing the 【"+ num +"】 element"); Element nameElem = element.element("name"); Element ageElem = element.element("age"); Element address = element.element("address"); // 獲取元素里面的內容 String name = nameElem.getText(); logger.info(name); String age = ageElem.getText(); logger.info(age); String addresselm = address.getText(); logger.info(addresselm); System.out.println("name = " + name + "\nage = " + age + "\naddress = " + addresselm); } } } ``` **運行結果：** Processing the 【1】 element name = 我是xml age = 20 address = Beijing Processing the 【2】 element name = 我是xml的滴滴 age = 19 address = ShangHai Processing the 【3】 element name = I`m jack age = 24 address = Tianjin Process finished with exit code 0
