Aha!

For those interested I finally came up with a solution to this--by
writing my own stripper markup.  Works great, and seemingly much
simpler than the basename patterns idea--though admittedly not as
smart.   (I'd be open to ideas for improving it...)

Basically, I added another zap var markup with this code:

Markup('zapstrip','<if','/\\{\\#h (.*?)\\}/e', 'zapstrip("$1")');
function zapstrip($x) {
	$xx = explode("|", $x);
	$x = substr($xx[1], strlen($xx[0]));
	return $x;
	}

Then I created this pagelist template:

[[#hggroup]]
(:if ! equal {=$Group} {<$Group}:)
(:input select subgroup '{#h {$$strip}|{=$Group}}':)
[[#hggroupend]]

What does this do?

Given wiki pages:

I can type (:pagelist group=Main-* strip=Main- fmt=#hggroup:) and
produce a pull down menu consisting of options One and Two--just what
I wanted.  Combined with ZAP and the subgroup vars, this can be used
to create pages at just the right place in a hierarchy automatically.
Really cool...

Suppose I could do a strip right also if needed...

Sivakatirswami, hope you are reading this.  I know you've been asking
for this repeatedly...

Cheers,
