正则表达式，允许数字之间的点

I need some help to build a RegEx that match numeric values and allow also one dot between numbers, example of valid match:

25.23.25
25.2323.5656.5656
25

Example of invalid match:

.25.23.25
25.2323.5656.5656.
25.
25.

Can any give me some help?

    ^\d+(?:\.\d+)*$

    This should do it.See demo.
