The first answer to
http://stackoverflow.com/questions/590747/using-regular-expressions-to-parse-html-why-notexplains
the disconnect between regex and HTML better than I can.
Here is a function that still requires correctness -- any unmatched ( or )
will cause it to return E with the position of the offending character --
but this routine returns *all* matched parentheses.
function strictTotalMatching S,B,E
put 0 into C
repeat with i = 1 to length(S)
if char i of S is E then
subtract 1 from C
if C < 0 then return "E" && i
put M[C],i & cr after R
else if char i of S is B then
put i into M[C]
add 1 to C
end if
end repeat
if C <> 0 then return "E" && i
sort lines of R numeric by item 1 of each
return R
end strictTotalMatching
