引入依赖

        <!-- dom4j -->
        <dependency>
            <groupId>dom4j</groupId>
            <artifactId>dom4j</artifactId>
            <version>1.6.1</version>
        </dependency>    

解析xml格式如下

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

<root> 
  <!-- 定时任务表   -->  
  <tasks> 
    <task id="1" taskName="定时任务一" methodName="method1" state="0" className="com.icanits.common.task.TestTask"> 
      <id>1</id>  
      <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>2</id>  
      <taskName>定时任务2</taskName>  
    </task>
  </tasks> 
</root>

解析xml字符串

　　@Test
    public  void tt() throws DocumentException {
        String xmlStr="<?xml version="1.0" encoding="UTF-8"?>
" +
                "
" +
                "<root> 
" +
                "  <!-- 定时任务表   -->  
" +
                "  <tasks> 
" +
                "    <task id="1" taskName="定时任务一" methodName="method1" state="0" className="com.icanits.common.task.TestTask"> 
" +
                "      <id>1</id>  
" +
                "      <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>2</id>  
" +
                "      <taskName>定时任务2</taskName>  
" +
                "    </task>
" +
                "  </tasks> 
" +
                "</root>";
        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<Element> 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);
        }
    }
