Hi Guys

From the databse I am getting four columns. One of the colums is of type CLOB. I am converting this data to a string. Now this String text has lot of nodes, now what I need is to show only the values of between <Description locale="en_US" type="admin"> and </Description>.

Would anyone know how I can use substring to display only description value. I have pasted a sample of how the Column data will be and also the jstl code of how I show the values.
I would reallly appreciate any help regarding this

<c:forEach var="elements" items="${reportResult}">
<tr>
           <c:forTokens items="${elements}" delims="," var="current" varStatus="sts">

                              <c:if test ="${sts.count==1}">
                               <td width = "50px" align="left" class="alt-color" >
                                    <c:out value="${current}" />
                              </c:if>
                              .....

                              <c:if test ="${sts.count==5}">
                                    <td width = "290px" align="left" class="alt-color" >
                               <c:out value="${current}" />
                              </c:if>

Hi ForceRs

The code which you pasted seems like to be in a scriptlet. Now what i needed is use the code inside jstl.
Because i will be getting the value like this

<c:if test ="${sts.count==5}">
<td width = "290px" align="left" class="alt-color" >
<c:out value="${current}" />
</c:if>

Is there a way I can use jstl to do what you wrote before

Thanks for all your help

You can use jstl functions.
<%@ taglib uri="http://java.sun.com/jsp/jstl/functions" prefix="fn" %>
It has all the necessary methods for doing substring, split etc.

Like this:
${fn:substring(message, fn:indexOf(message, <Description>)+1, fn:indexOf(text, </Description>))}

Oops.. it should be.
${fn:substring(message, fn:indexOf(message, <Description>)+1, fn:indexOf(message, </Description>))}

Also, there are other EL functions like substringAfter, substringBefore, etc. Check them on the JSTL.
