All Implemented Interfaces:

I_CmsResourceWrapper

public class CmsResourceWrapperXmlPage
extends A_CmsResourceWrapper

A resource type wrapper for xml page files, which explodes the xml pages to folders.

Every resource of type "xmlpage" becomes a folder with the same name. That folder contains the locales of the xml page as folders too. In the locale folder there are the elements for that locale as files. The files have the names of the elements with the extension "html". Additionaly there is a file in the root folder of that xml page that contains the controlcode of the xml page. This file has the name "controlcode.xml".
