[Boost-users] using regex for in-place string modification

I want to use regex to modify a string in place.  In particular, I've read
the contents of a file into a string, now I want to do some search/replace
functions on the string, then write the modified string back out to the
original file.  I've looked through the regex documentation, including the
October 2001 DDJ article, but I don't see any way to modify a string in
place.  From what I can tell, regex_merge looks like it does the kind of
thing I want, except it doesn't seem to modify in place.  I'd prefer to
avoid creating two strings of each file's contents, one before regex
processsing, one after.  Is there functionality in regex that will let me
modify a string in place?

Thanks,

Scott
