Hi Mikael,
If you wish to eliminate anything that is not a number, then this should work:
AllVersions[VersionNumber.ToString.Matches('^[0-9]*$')]Best regards,

What if your list is not only numbers? ToInterger will then crash the script. It may be a list of strings intended for numbers but may also contain text provided by the user. How to test the list for numbers values only (e.g. $List[0..9] .ToInteger
One limitation of the first option is using Branch in versioning, which will result in including characters in the version number, for instance, Version=2a1.
The image below shows an example.
