i'll build it for a fee. :-)
I don't think its "required" if the input can be limited to something reasonable. Not that I would want to try and code such a parser myself even for a limited set of equations.
Of course a lexicographical parser would be a great solution if money and time were no problem.

Hi,
Is there a way to evaluate an equation contained in a string within an AWK script?
For example:
A = "(5*2)-1" (this equation is read from a file and varies line by line)
In this example, I can't see any way to get an answer of 9 unless I do:
cmd = "awk 'BEGIN{print "A"}'"

NAME
tdom - tdom is an expat parser object extension to create an in-memory DOM tree from the input while parsing.
SYNOPSIS
package require tdom
set parser [expat]
tdom $parser enable
_________________________________________________________________
DESCRIPTION
tdom adds the C handler set "tdom" to an tcl expat parser obj. This handler set builds an in-memory DOM tree out of the input, parsed by
the parser. A DOM tree created this way behave exactly like a DOM tree created by the "dom" command (see there). In fact, tdom is only
another interface to the same functionality; it uses the code behind the dom code for building the DOM tree.
tdom parserObj enable
Adds the tdom C handler set to a Tcl expat parser object. Next time, the parser parses input, the tdom C handler functions create an
in-memory DOM tree.
tdom parserObj getdoc
Returns the DOM tree as domDoc (see there) object.
tdom parserObj setResultEncoding
See the method setResultEncoding of the dom command.
tdom parserObj setStoreLineColumn ?boolean?
See the method setStoreLineColumn of the dom command.
tdom parserObj remove
Removes the tdom C handler set from the parser object.
tdom parserObj keepEmpties
See the option -keepEmpties of the dom command.
tdom parserObj setExternalEntityResolver script
