Here's how I do it:

My .emacs starts with this comment:

;; Xemacs doesn't read this file, but we use Xemacs' init file in Emacs.
;; However, Emacs does its own customizations.

After a bunch of code useful only in Emacs rather than Xemacs, it ends
with:

(let ((xemacs-init-file
       (expand-file-name "init.el" "~/.xemacs")))
  (load-file xemacs-init-file))

Inside the xemacs-init-file file, there is the following comment:

;; Note: this file is shared by FSF Emacs and Xemacs, hence the
;; "(featurep 'xemacs)" conditionializations below.

Then, code that only is needed or works in Xemacs has

(when (featurep 'xemacs) ...)

wrapped around it and code that only is needed or works in Emacs has

(unless (featurep 'xemacs) ...)

wrapped around it.

e.g. the following lines are in init.el:

  (when (featurep 'xemacs)
      (set-variable 'default-toolbar-visible-p nil))

Hope this helps.
