DOM4J /文件

Question

Node existingUserNode = loginDoc.selectSingleNode("/returningUser"); 
String username = existingUserNode.selectSingleNode("/username").getText(); 
String password = existingUserNode.selectSingleNode("/password").getText(); 

XPATH解析爲

<?xml version="1.0" encoding="UTF-8"?><returningUser><username>user</username><password>password</password></returningUser> 

返回null。

我不認爲我的xpath是錯的？或者我使用錯誤的方法？

Answer 1

的語法應該是./username和./password ...上面我找一個水平通過引用根

Answer 2

試試這個

Node existingUserNode = loginDoc.selectSingleNode("/returningUser"); 
String username = existingUserNode.selectSingleNode("/username").getNodeValue(); 
String password = existingUserNode.selectSingleNode("/password").getNodeValue();
