Spyntax class/api

hi,
does anyone know of a Spyntax class/api in Java or Autoit or VB?
anything?
I searched and couldn't find any and it surprised me, i thought it was some kind of standard, maybe the official name is not Spyntax?

for those who don't know what Spyntax is, it's where you take a string/text like
{option1|option2|{option31|option32}}
and it gives you back just one of the options...
and i'm looking for a function that will be something like
String Spyntax(String txt)

10x.

I am also looking for this, excepts in a php class. I imagine it uses preg_expressions to handle things
