what can I do with regexp match?

[Seweryn Kokot]

Hello,

I would like to have a function that visits all the tex files included
in main.tex file. I wrote the following function:
(defun my-document-files ()
  "Open all document files"
  (interactive)
  (while (re-search-forward "\\\\include{\\(.*\\)}")
         (find-file (concat "~/nauka/doktorat/thesis/" "\\1" ".tex"))))

But it doesn't work since \\1 is not replaced by regexp match. The
result is that the function visits \1.tex file. The question is how to
process the regexp match to make it argument for find-file or more
general question how to save the match in a variable or list?

regards,
