need to evaluate formula as defined in string

[bordonbert]

Hi.

I'm very new to advanced XML work and have a specific need. I have data including numerical values extracted from XML. In the XML is an attribute which is basically a formula defined as a single text string. I have to find a way of evaluating the formula with values from the rest of the data. The only step which I am unable to fulfil is that step of going from a string expression to parsing it for the result.

I could do this with a simple C++ formula parser class but I can't help thinking that there must be a simple way to do this directly from the XML if I have the right tool. At the moment I am using Xerces and have XQilla available too.

Many thanks.

If that "c++ formula parser class" is what you could--,my understanding would be: meaning not only you have the competence but also meaning that it integrates well with the application,--by all mean use it. (I limit my time to not more than the time spent on op posting the question.)
