I am looking for a sophisticated graphical FSM editor that can export a model in a well-documented output format, like SCXML or similar.
Can anybody recommend me a tool?

I guess my question is best explained with an (simplified) example.
Regex 1:
^\d+_[a-z]+$
Regex 2:
^\d*$
Regex 1 will never match a string where regex 2 matches.
So let's say that regex 1 is orth...

Something that can convert
r"a+|(?:ab+c)"
to
{
(1, 'a') : [2, 3],
(2, 'a') : [2],
(3, 'b') : [4, 3],
(4, 'c') : [5]
}
or something similar
and accepting in 2 or 5
