Yep, check out emacs-server and emacs client.

I have only used this for GNU emacs, but I assume XEmacs has the same
or related functionality.

In a nutshell, from within emacs run the function server-start.

Then, create the text you want to feed to an existing emacs session,
by writing to a temporary file:

  >>> file('somebuffer', 'w').write('Some message\n')

and send it to the emacs server with

  >>> os.system('emacsclient "somebuffer")

This will open the buffer 'somebuffer' in the already running emacs
session with the text 'Some message'

Do you know about pymacs BTW http://www.iro.umontreal.ca/~pinard/pymacs?
