GNAT has a pattern matching package based on spitball(sp?) patterns
constructs.

Have a look at g-regexp.ads if you are using GNAT!

And a regular "regular expression" package too. See adainclude/g-regexp.*

TASH is an Ada 95 binding to Tcl/Tk.  Among other things, you'll
get regular expression pattern matching.

Here's an excerpt from the (hopefully) soon to be released new and
improved thick binding.  This excerpt and the example provide regular
expression pattern matching to find patterns in elements of Tash lists.
There will also be the capability to perform regular expression matches
directly on strings as well.  I just happening to be finishing up the
list regexp match right now.

--------------------------------------------------------
-- Use regular expressions to search a list. Index returns
-- the index (in the range 1..Length(Source)) in Source
-- of the element which matches the specified regular
-- expression. Returns 0 if the pattern is not found.
--------------------------------------------------------
function Index (Source : in Tash_List;
                Regexp : in String;
                Going  : in Ada.Strings.Direction := Ada.Strings.Forward)
   return Natural;

Here's an example:

declare
   use type Tash.Lists.Tash_List;
   Target_String : Tash.Lists.Tash_List := Tash.Lists.To_Tash_List (
      +"this Tash string is an element of a Tash list",
     +"here's a second element");
begin
   if Tash.Lists.Index (Target_String, "[tT][aA][sS][hH]") > 0 then
      Ada.Text_IO.Put_Line ("Tash found");
   end if;
 end;
