dom and jsp interacation

[Seetha Rama Krishna <ram_kurra@xxxxxxxxxxx>]

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
