"man re_format"
My immediate task is to convert some dates in HTML files from
inside-out to ISO format
i.e. from 07/06/2006 to 2006-07-01
and have tried things like
\(:d:d\)\/\(:d:d\)\/\(:d:d:d:d\)
and
\([0-9][0-9]\)\/\([0-9][0-9]\)\/\([0-9][0-9][0-9][0-9]\)
for the search specification
with
\3-\1-\2
and
$3-$1-$2
and
$4-$3-$2
for the replace specification, but it apparently does not like sub-
matches bracketed with \( and \), and without sub-matches, I can't
use the sub-matched buffers in the replace.
I just tried:
([0-9][0-9])/([0-9][0-9])/([0-9][0-9][0-9][0-9])
and
\3-\1-\2
and it worked fine - I don't think you want to escape the parens
(since would mean that you'd be looking for literal parens and not
grouping).
