引入依赖

        
        <dependency>
            <groupId>dom4jgroupId>
            <artifactId>dom4jartifactId>
            <version>1.6.1version>
        dependency>    

解析xml格式如下

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

<root> 
    
  <tasks> 
    <task id="1" taskName="定时任务一" methodName="method1" state="0" className="com.icanits.common.task.TestTask"> 
      <id>1id>  
      <taskName>定时任务一taskName>  
    task>  
    <task id="0c686f79-e64e-4dab-b91b-5a6dcfb07f6b" taskName="定时任务2" methodName="test2" className="com.czy" state="0"> 
      <id>2id>  
      <taskName>定时任务2taskName>  
    task>
  tasks> 
root>

解析xml字符串

　　@Test
    public  void tt() throws DocumentException {
        String xmlStr="<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n" +
                "\n" +
                " \n" +
                "    \n" +
                "   \n" +
                "     \n" +
                "      1  \n" +
                "      定时任务一  \n" +
                "      \n" +
                "     \n" +
                "      2  \n" +
                "      定时任务2  \n" +
                "    \n" +
                "   \n" +
                "";
        Document document = DocumentHelper.parseText(xmlStr);
        Element rootElement = document.getRootElement();// 获取根节点
        System.out.println("根节点名称: "+rootElement.getName());
        Element tasks = rootElement.element("tasks"); // 获取tasks节点
        List elements = tasks.elements();// 获取 tasks下的所有子节点
        for (Element element : elements) {
            String id = element.selectSingleNode("./id").getText();
            String taskName = element.selectSingleNode("./taskName").getText();
            System.out.println(taskName+" === "+id);
        }
    }
