Hi,
when dealing with expressions characterized by a start- and end
string, quite often a little function is convenient:
Below a simplified example:
(setq startstring "abc")
(setq endstring "def")
(defun my-start-end-delete ()
" "
(interactive "*")
(let (beg)
(while (search-forward startstring nil (quote move) 1)
(setq beg (match-beginning 0))
(when (search-forward endstring nil (quote move) 1)
(delete-region beg (match-end 0))))))
abcABCDEFdefAAAAAAAAAA -> AAAAAAAAAA
