["Matt Chapman" <mpchapman@xxxxxxxxx>]

Hi Fernando,

If you get the PointcutElement, you can cast it to ISourceReference
then call getSource().
But to keep JDT happy by default "Java-compatible" contents are
returned, not the real contents. You have to request this from the
containing AJCompilationUnit, by calling requestOriginalContentMode(),
and then discardOriginalContentMode() afterwards.

There is an example of this in the org.eclipse.ajdt.core plugin, in
AspectRenameParticipant.java around line 206.

Regards,

Matt.
