I would like to parse an external XML file (an RSS feed) in a Freemarker template. Is this possible? It's simple when the RSS feed would be stored in the repository, I would only need to call the reference to the document like this:
I don't believe Freemarker allows this out of the box. However, Alfresco allows you to add your own apis to Freemarker. You could write a Java class that pulls in the URL by exposign a Custom Root object to Freemarker. It's quite easy, I've done it several times for projects.
It's actually not too hard to expose Java in Freemarker. See this link for a sample I just uploaded. The sample also allows you to pull in output of a web script into Freemarker, so that piece could be useful as well. If you write a Web Script that does what you need to do, you can include that easily in FreeMarker.
