正则表达式可以在.Net中运行，但不能在经典ASP中运行

Question

I have the below regular expression which is working fine in .NET however it is not working in Classic ASP. The Regular expression is used to validate for a least one digit and one character.

The expression is:

Set regPassword = New RegExp
regPassword.Pattern = "^(?=.*\d)(?=.*[A-Za-z]).{6,30}$"
Response.Write(regPassword.Test("Test456"))

The result of the above returns False.

Does anyone know a workaround for this?

Answer 1

 ^.(?=.*\d)(?=.*[A-Za-z]){6,30}

Here is a good resource on the VBScript Regex engine.

Edit: According to the comments, this works?

(.*[a-zA-Z].*[0-9]|.*[0-9].*[a-zA-Z])
