I have ascii text in which simple SGML-like notation is used to
delimit "interesting" areas, like: <foo> interesting area </foo>.  And
I would like to define a simple (I hope) command of the form "M-X
highlight-objects" which in this particular case would take "foo" as
an argument and highlight all instances of "foo" areas in the current
buffer.

If anyone out there has already implemented a "highlight-objects"
command of this sort, or something similar, I would be grateful for
some simple examples.  I assume that defining zones is the right thing
to do, but I don't have any experience using this feature of Epoch.


Many thanks,

Carl

RE: highlighting interesting areas of text that has SGML-like notation

I use the hilit.el package to do something like this for sgml like
documents that I edit (VAXDocument .sdml files).  I got my copy
of hilit.el from the author, Paul Nakada (pnakada@oracle.com).

You simply make a custom mode (say SGML mode) and define a list of
regexp's that do specific types of hiliting.  All you have to do
is give a regexp for the start of the region, and a regexp for the
end of the region.

Here is an example of c-mode highlights
      '(("/\\*" "\\*/" 0)     ;; hilight comments with style 0
	("^#.*" nil 9)        ;; hilight # at beginning of line with style 9
	("^typedef.*" nil 1)  ;; typedefs with style 1
	("^struct.*" nil 1)   ;; structs with style 1
        ("^#if 0" "^#endif" 3 )  ;; #if 0 followed by #endif with style 3
	("^enum.*" nil 1)))      ;; enum statements with style 1
