this works:
%s/\%(\%(foo=\"\)\@<=\%([0-9A-F]\{2\}\s\)*\)\@<=\([0-9A-F]\{2\}\)/0x\1/g
In using :s with the /g flag, I take it the potential changes are
marked first, and then executed, per line?
Somewhat more generally, the pattern above could be:
%s/\%(\%(foo=\"\)\@<=\%(\%(0x\)\?[0-9A-F]\{2\}\s\)*\)\@<=\([0-9A-F]\{2\}\)/0x\1/g
which works both with and (repeatedly) without the /g flag.
I prefer when dealing with that many special characters to use the
very-magic form:
%s/\v%(%(foo\=")@<=%(%(0x)?[0-9A-F]{2}\s)*)@<=([0-9A-F]{2})/0x\1/g
... but that's obviously a matter of personal preference.
Thank you,
