Lars Trieloff updated SLING-985:
Attachment: SLING-985.patch
This patch provides an atom taglib that covers the atom core vocabulary plus
the opensearch and mediarss extensions. Bound to a
namespace prefix like atom you can create a feed using:
<%@ page session="false" %><%
%><%@ page import="
javax.jcr.*,
java.util.Iterator"
%><%@ taglib prefix="sling" uri="http://sling.apache.org/taglibs/sling/1.0"; %><%
%><%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"; %><%
%><%@ taglib prefix="fmt" uri="http://java.sun.com/jsp/jstl/fmt"; %><%
%><%@ taglib prefix="fn" uri="http://java.sun.com/jsp/jstl/functions"; %><%
%><%@ taglib prefix="atom" uri="http://sling.apache.org/taglibs/atom/1.0"; %>
<%
NodeIterator i = currentNode.getNodes();
while (i.hasNext()) {
Node n = i.nextNode();
pageContext.setAttribute("n", n);
%>
<%
}
%>
This example can be used as the default jsp for the .feed extension. With
following default JSP for the .entry extension, it becomes possible to generate
a feed out of any JCR node. The feed would simply list the child entries.
A possible entry.jsp would look like this:
<%@ page session="false" %><%
%><%...@include file="/libs/wcm/global.jsp"%><%
%><%@ taglib prefix="sling" uri="http://sling.apache.org/taglibs/sling/1.0"; %><%
%><%@ taglib prefix="atom" uri="http://sling.apache.org/taglibs/atom/1.0"; %>
<%
if (currentNode.hasProperty("jcr:title")) {
%><%=currentNode.getProperty("jcr:title").getString() %><%
} else if (currentNode.hasProperty("cq:title")) {
%><%=currentNode.getProperty("cq:title").getString() %><%
} else if (currentNode.hasProperty("title")) {
%><%=currentNode.getProperty("title").getString() %><%
} else {
%><%=currentNode.getPath() %><%
}
%>
<%
if (currentNode.hasProperty("jcr:description")) {
%><%=currentNode.getProperty("jcr:description").getString()
%><%
}
%>

> Having a JSON output for Sling is quite nice, but many web applications
> require RSS/Atom support these days. Having an extension module that provides
> a tag library for creating Atom feeds and atom entries out of JCR nodes would
> be very helpful.
