unfortunately no, we could at best provide a suggested one but that's all
Take for example
[0-9]{1-3}|[0-1]{5}
with an input of
1210
on one side of the branch you would consider the 0 to be the first character
in error on the other side of the branch the 2 . You can't guess which one
the user made an error with. I think your requirement makes no sense, unless
I misunderstood it.
Point is xmlregexp was designed for validating XMLSchemas datatypes, so it
is built to give a yes/no answer, it was not designed to build general
regexp services.
