Xml到基於屬性值的java解析到一個單獨的變量

Question

我正在從事XML到java的解析。我有一個類似於這個場景。

我需要解析所有EMPLOYEE元素與屬性PERMANENT="Y"在一個構件和另一個構件屬性PERMANENT="N"。

<EMPLOYEE PERMANENT="Y"> 
    <DETAILS NAME="AA" ID="1" AGE="28" /> 
    <DETAILS NAME="BB" ID="2" AGE="29" /> 
</EMPLOYEE> 
<EMPLOYEE PERMANENT="N"> 
    <DETAILS NAME="CC" ID="3" AGE="28" /> 
    <DETAILS NAME="DD" ID="4" AGE="29" /> 
</EMPLOYEE> 

的Java

public class Employee 
{ 

    // @XStreamAlias("EMPLOYEE") and attribute PERMANENT="Y" 
    private Details permanentEmployee; 

    // @XStreamAlias("EMPLOYEE") and attribute PERMANENT="Y" 
    private Details tempEmployee; 

} 

我不知道如何做到這一點。

有人可以幫助我。

      Element elt1 = (Element) firstNode3; 
      String att=elt1.getAttribute("PERMANENT");

      NodeList nodes = elt1.getElementsByTagName("DETAILS");

      } 

     }//end of for
