public class CmsJspTagContentLoad
extends CmsJspTagResourceLoad
implements I_CmsXmlContentContainer

Implementation of the <cms:contentload/> tag, used to access and display XML content item information from the VFS.

Since version 7.0.2 it is also possible to store the results of the content load in the JSP context using a CmsJspContentLoadBean. Using this bean the loaded XML content objects can be accessed directly using the JSP EL and the JSTL. To use this feature, you need to add the var (and optionally the scope) parameter to the content load tag. For example, if a parameter like var="myVarName" is provided, then the result of the content load is stored in the JSP context variable myVarName with an instance of a CmsJspContentLoadBean.

Since:

6.0.0
