search/replace in gettext files

[Tim Morley <t_morley@argonet.co.uk>]

Hi.

Not sure if this group is the ideal place for this question, but 
couldn't find a newsgroup dedicated to GNU gettext questions. Please do 
point me in the right direction if there's a better place.

My question: I'd like to be able to do a global search and replace 
operation on the translations held in a tree of .po files. The original 
English strings mustn't be changed, so I need something that will parse 
the files, pick out the translated text, and perform the search/replace 
only on those elements.

I'm aware of msgexec, and I attempted this:

   ~$ msgexec -i temp.po sed s/foo/bar/g

but the result was just a list of the changed items sent to stdout, not 
the whole original file with the each 'foo' changed to 'bar' as I need.

Any suggestions or advice gratefully received.

Thanks in advance.


Tim
