Parse xml to different members based on Attribute value

I am working on XML to java parsing. I have a scenario similar to this.

I need to parse XML into java based on the attribute value.

I need to parse all EMPLOYEE elements with attribute PERMANENT="Y" in one member and with attribute PERMANENT="N" in another member.

<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>

Java

public class Employee
{

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

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

}

I am not sure how to do this.

Can some one help me.

You can do it using the using the java xml api

The XPath expression to select the "DETAILS" nodes will look something like this:

import javax.xml.xpath.XPath;
import javax.xml.xpath.XPathFactory;
//...

XPath xPath =  XPathFactory.newInstance().newXPath();
String expression = "/documentBody/EMPLOYEE[@PERMANENT="Y"]/DETAILS"
NodeList nodeList = (NodeList) xPath.compile(expression).evaluate(xmlDocument, XPathConstants.NODESET);

This returns a nodeList that you need to then iterate through for each DETAILS node, which I would assume describes one employee.
