[tuongtu3]

Hello All,
I'm loking for code to remove two dot or three dot in front of text string but not single dot in middle. If I use replace then it remove all dot.

Exp:

..123 => 123
..abc => abc
...456 => 456
...def => def
123.456 => 123.456
...123.456 => 123.456
..abc.123 => abc.123
456789 => 456789

Regards,
