B4J Question Separate the string at the decimal point

[strupp01]

I want to separate a string at the decimal point into two strings with the command 'Regex.split'. This does not seem to work.
Example: '123.456 cm' split into '123' and '456 cm'
Dim str () As String = Regex.split (".", "123.456 cm")

Someone knows why?

You have to escape the character, it is a special one: Regex.split ("/.", "123.456 cm")

I know.

'.' is a special character in regex patterns (= match everything).
You need to escape it:

Dim str() As String = Regex.Split("\.", "123.456 cm")
