Thanks for the help.

My platform is Win32 and I was able to create a class:

class mystring: public std::iterator<std::bidirectional_iterator_tag, char >

mystring class opens the input file and maps it into memory using:

and I pass this into regex_replace. It seems to work - any thoughts?

Thanks again
