[jboss-dev-forums] [Design the new POJO MicroContainer] - Getting content of XML element

[kabir.khan@jboss.com]

Can somebody please tell me how to get the contents of the annotation? i.e. I want: @org.jboss.test.microcontainer.beans2.Annotation1. It does not appear to be accessible from any of the things passed in to the methods of AnnotationOverrideHandler?

Also, for a similar schenario I will need to construct a org.w3c.dom.Element from the nested contents of a element. Is that possible?
