[opencms-dev] get item count with contentloop

[Mario Jäger]

Hi,

To get the number of items in a list using EL, you can use the JSTL 
function "length": 
http://download.oracle.com/docs/cd/E17802_01/products/products/jsp/jstl/1.1/docs/tlddocs/fn/length.fn.html

This function returns the number of items in a collection, or the number 
of characters in a string.

In the following example the number of the nodes "Channel" in a xml 
content is given out:
...
<%@ taglib prefix="fn" uri="http://java.sun.com/jsp/jstl/functions" %>
...
<cms:contentload collector="singleFile" param="<path to the file>">
   <cms:contentaccess var="content" scope="page" />
   ...

   // get the number of the items "Channel"
   <c:set var="count" value="${fn:length(content.valueList.Channel)}" />
   count: <c:out value="${count}" />

   ...
</cms:contentload>

-- 
Kind Regards,
Mario.
