If its HTML you need, you could substitute a call to 
HTML::Parser instead with a XMLSub <asp:form> to 
look for the input tags.  You could also do this
all at once at the Script_OnFlush event to parse
both the xform and form at runtime.

If you wanted just a XMLSubsMatch approach, you will have
to work backwards, because inner tags are evaluated
first as sub routines.  If you need the input data when you 
evaluate the <asp:form>, then you could try using script
globals to capture data for you, like in each input tag
you could set something in $Inputs{$id} = $data and 
then reference %Inputs in your <asp:form> ... that's
pretty backwards, and is a limitation with a pure 
XMLSubs approach to a problem like this.

Best of luck, and I am very interested in what you 
end up with.
