getting elements from xml file using DOM

Hi Techies,
I am reading an xml file using DOM. Here is my xml file

 <Date>
<Today>
   <id>12345</Today_Id>
   <name>TODAY</Today_Name>
   <data_Type>date</Today_Data_Type>
</Today>
<EndOfWeek>
   <id>12345</Today_Id>
   <name>TODAY</Today_Name>
   <data_Type>date</Today_Data_Type>
</EndOfWeek>
<EndOfMonth>
</EndOfMonth>
</Date>

Here i want to get only <Today> and <EndOfWeek> not the child nodes of <Today>,<EndOfWeek>,  when i read the xml file . How can I do this one.

              I tried with the following code.
DocumentBuilderFactory factory = DocumentBuilderFactory
                    .newInstance();
            DocumentBuilder parser = factory.newDocumentBuilder();
            Document document = parser.parse(xmlFileName);
            Element documentElement = document.getDocumentElement();
            NodeList todayNodeList = documentElement                   .getElementsByTagName("Today");

          How can  get only first level of nodes. That is  I want get only Today,EndOfWeek,EndOfMonth.
