Hi John,

Thanks for your kind reply.

My code is based on this program of yours:

http://patriot.net/~ramon/regex_iterator_example.cpp.txt

My data is structured like this:

[Unique ID1]
Variable Name = Variable Value
Variable Name = Variable Value
Variable Name = Variable Value

[Unique ID2]
Variable Name = Variable Value
Variable Name = Variable Value
Variable Name = Variable Value
Variable Name = Variable Value

All I need to do is to extract the different parts, to be saved in a 
map. In my first callback, I divide every section into (a) Unique ID, 
and (b) rest of the (multiline) block. Once I have the latter, I make a 
call to a second callback to break the LHS and the RHS of each 
assignment expression.

So you say that the callback is really not required?

Thanks!
