Is there any way to perform an interactive replace (query-replace) of
regular expressions recursively in all or some (specified by a regular
expression) files present in a directory tree.


Many thanks in advance,

Not sure what you mean by recursively, but if you just mean 
doing the equivalent of query-replace-regexp on mulitple
files, take a look at etags:

1) First make a 'TAGS' file to include the files you want (shell)

   $ etags `find . -name "*.blah.*.foo"`

   This makes a TAGS file in the current directory

2) In emacs, do M-x tags-query-replace.  It will query 
   for from-expression, to-expression, then the location
   of the TAGS file.

etags is extremely powerful for language specific
stuff, but works just fine for iterating over
a set of files.

In addition to TAGS files, another approach is M-x find-dired RET to
generate a dired buffer with the files, then invoke Q (not q).

You need (require 'dired-x) in ~/.emacs for Q to work.

Edit the directory (emacs goes into dired mode), mark the files, and
use the Q command in dired.
