Regex question

Hello,

I want a regex for matching a 10 digit number with optional
'*' and '?'
characters for wildcard searches. The * or ? can not appear
in
beginning if alone.

I came up with following regex but unfortunately doesnt work
all the
time. Could anyone please correct me where I am wrong.

^\d(\b(\d+\*\d+)*|(\d+\?\d+)*|(\d*\*$)|(\d*\?$)
b)+

Thanks
superman

you question is not very clear. Do you mean the * or ? can
not be
stand-alone, and it can be the first character if they are
not
standaloe, like *123

why do you want word boundaries. They look strange and most
possibly, I
think, they will fail many of your matches.

Can you provide us with some samples, i.e. are some of the
following
strings valid:

*
?*
***
*12*34
1234*
12*34?
12?3*4
123?**4
