Excel中的表达式语法？

Question

I'm struggling with validating a regex syntax that I'd like to use in Excel (VBA). The syntax runs good in every validator engine on the net but I can't get it to work in Excel.

Could anyone help me with this and I'd most grateful.

The expression:

    ^.+(?<!/)(?=/?[RP]\d) 

Data to validate: ABC12345/67/R1A

Expected result: ABC12345/67

Answer 1

Please check this regex ^.+(?<!/)(?=/?[RP]\\d) as its not giving the expected output. It works with ^.+(?=/[RP]\\d) . Below is sample code.

Sub Main()

    Dim stringToValidate As String
    Dim stringResult As String


    stringToValidate = "ABC12345/67/R1A"
    stringResult = getData(stringToValidate)


End Sub

Function getData(ByVal str As String) As String
    Dim objRegEx As Object
    Set objRegEx = CreateObject("VBScript.RegExp")
    objRegEx.IgnoreCase = True
    objRegEx.Global = True

    objRegEx.Pattern = "^.+(?=/[RP]\d)"

    Set allMatches = objRegEx.Execute(str)

    For i = 0 To allMatches.Count - 1
        result = result & allMatches.Item(i)
    Next

    getData = result
End Function
