I'm trying to figure out how to build a dynamic parser but got stuck....

I need a parser that can be configured run-time to parse different
languages, or well... actually data in different text formats from
several business systems.

A kind of dynamic parser I suppose one could call it.

Using the normal lex/yacc approach is not enough as it requires me to
write a specification for each type of input and then compile this
into a parser. I need to have a run-time "engine" that takes a
specification in some form and knows from that specification in what
format the input is in and how to parse it.

Pointers in the right direction would be great.

thanks in advance...
