做自动化测试的人，都应该对XPATH很熟悉了，但是在用JAVA解析XML时，我们通常是一层层的遍历进去，这样的代码的局限性很大，也不方便，于是我们结合一下XPATH，来解决这个问题。

所需要的JAR包：

dom4j.jar

jaxen.jar

xmlbeans.jar

具体的代码如下：

public class ParseXml {    private String filePath;    private Document document;     public ParseXml(String filePath) {             this.filePath = filePath;        this.load(this.filePath);    }      private void load(String filePath){        File file = new File(filePath);        if (file.exists()) {            SAXReader saxReader = new SAXReader();            try {                document = saxReader.read(file);            } catch (DocumentException e) {                    System.out.println("文件加载异常：" + filePath);                          }        } else{            System.out.println("文件不存在 : " + filePath);        }              }      public Element getElementObject(String elementPath) {        return (Element) document.selectSingleNode(elementPath);    }      @SuppressWarnings("unchecked")    public List
     
       getElementObjects(String elementPath) {        return document.selectNodes(elementPath);    }    @SuppressWarnings("unchecked")    public Map
      
        getChildrenInfoByElement(Element element){        Map
       
         map = new HashMap
        
         ();        List
         
           children = element.elements();        for (Element e : children) {            map.put(e.getName(), e.getText());        }        return map;    }    public boolean isExist(String elementPath){        boolean flag = false;        Element element = this.getElementObject(elementPath);        if(element != null) flag = true;        return flag;    }     public String getElementText(String elementPath) {        Element element = this.getElementObject(elementPath);        if(element != null){            return element.getText().trim();        }else{            return null;        }          }    public static void main(String[] args) {        ParseXml px = new ParseXml("config/TestBaidu.xml");        List
          
            elements = px.getElementObjects("/*/testUI"); }}
