The "%s/foo/bar/" notation is for fixed (not variable) regexp
strings only. Your original request didn't mention trying to
build the substitutes dynamically, so I assumed they were fixed
regexps. It's looking for the literal text "$from1", not the
value assigned to "from1" (namely "xxxxx"). So you'd want to use
%s/xxxxx/yyyyy/g
%s/xxx/\x79yy/g
It can be hacked using the exec() command:
exec '%s/'.from1.'/'.to1.'/g'
exec '%s/'.from2.'/'.to2.'/g'
with varying degrees of escaping as needed around the from[12]
and to[12]. You can read about the escape function at
:help escape()
