Android Question [B4X] Regex limit to one dot

[Alexander Stolte]

How can i replace all double dots and only allow one dot per string?
Example:
Allowed:
1
1.2
10.20
Not Allowed:
.1
1.0.0

 

[Erel]

For Each s As String In Array("1", "1.2", "10.20", ".1", "1.0.0")
    Log(s & ": " & Regex.IsMatch("\d+\.\d+|\d+", s))
Next
