Re: [xsl] How to dynamically evaluate an equation in the input XML document?

Have you done this kind of dynamic equation solving using XSLT? If so,
how did you do it?

What is described is not "equation solving", it is just evaluation of a
function for a certain value of a variable.

Solving an equation requires to have an equation in the first place. That
is, two expressions connected by the "=" operator.

Then, solving the equation is to find all the sets of variable values, for
which this equation holds (the = is true).

Please, be more precise and do not confuse these well-known concepts.

Hi Folks,

I have XML documents like this:

    <equation>(Fahrenheit - 32) * (5/9)</equation>

The document contains an equation which might contain variables. If it
does contain variables, then I need to fetch their values and replace the
variables in the equation with their values and then compute the value of
the equation.

Have you done this kind of dynamic equation solving using XSLT? If so, how
did you do it?

Any suggestions on how to approach this problem would be appreciated.
