While this can be done with sed, it's generally a lot easier to do with
python or perl, particularly when dealing with multi-line replacement
patterns.
It was this type of job that led me to perl in the late 1980s as perl was a
lot easier to understand than advanced sed features, and there was only one
regular expression syntax to remember. Currently I use python for most
things, but don't want to start a scripting language wars thread here.
There's a very useful script 'replace' in the Kernighan and Pike book "The
Unix Programming Environment" which uses sed for in-place replacements as
an example of exception handling (MySQL has a similar 'replace' script but
with different arguments which tells me that their developers hadn't done
much basic *nix study as this book, while old, is still excellent).
The best book I've ever read on sed is "Unix Text Processing" by Dougherty
and O'Reilly which covers many *nix utilities.
