I'm a little unsure about exactly what you want to do, but here is
what I think you are saying:

You have a file stored in a string, let's call it fileString.  You
want operator[] to return the position in fileString where the 
field_name field is located.  Why not use the STL hash_map to
map field names to string locations?

Hope this helps,

Mark.
