Hello Techies,
          I am having one jsp thru which I am getting tag's of the xml file. I want to get the values of these tags when perticular tag is required.
       Here is sample xml file
<Date>
<Today>
   <Today_Id>12345</Today_Id>
   <Today_Name>TODAY</Today_Name>
   <Today_Data_Type>date</Today_Data_Type>
</Today>
<EndOfWeek>
   <EndOfWeek_Id>6789</EndOfWeek_Id>
   <EndOfWeek_Name>ENDOFWEEK</EndOfWeek_Name>
   <EndOfWeek_Data_Type>date</EndOfWeek_Data_Type>
</EndOfWeek>
</Date>

    lets us suppose that from jsp I got "Today" as request. Now I created the instance and parsing the xml file.

DocumentBuilderFactory factory = DocumentBuilderFactory
                    .newInstance();
            DocumentBuilder parser = factory.newDocumentBuilder();
            Document document = parser.parse(xmlFileName);
            Element documentElement = document.getDocumentElement();
            NodeList nl = documentElement
                    .getElementsByTagName("Today");
            ArrayList mapp = iteratingEachNodeChildValueList(nl);

       For the next request is EndOfWeek. Here the question arises
"does i need to create the instance of parser and read the file for each request??"

regards,

ramu
