Question

How to split comma which ignores if the value is enclose to double quotes.

Data available:

3545,Albert,”Mathias Albert, Lars-Erik Cederman and Alexander Wendt
(eds)”,2010

Should be splitted in an array:

arr(0) = "3545"
arr(1) = "Mathias Albert, Lars-Erik Cederman and Alexander Wendt (eds)"
arr(2) = "2010"

Answer 1

While using the ADO Text Driver would probably be the best way in the long run, you can use a specific/custom RegExp for a quick & dirty ‘use just once’ script:

>> Set r = New RegExp
>> r.Pattern = "^([^,]+),([^,]+),""([^""]+)"",(.+)$"
>> s = "3545,Albert,""Mathias Albert, Lars-Erik Cederman and Alexander Wendt (eds)"",2010"
>> Set m = r.Execute(s)
>> ReDim a(3)
>> For i = 0 To UBound(a)
>>     a(i) = m(0).SubMatches(i)
>> Next
>> WScript.Echo Join(a, vbCrLf)
>>
3545
Albert
Mathias Albert, Lars-Erik Cederman and Alexander Wendt (eds)
2010
>>

To cope with empty fields, the .Pattern needs some further fiddling.

If you prefer Split(), something like this:

>> s = "3545,Albert,""Mathias Albert, Lars-Erik Cederman and Alexander Wendt (eds)"",2010"
>> ReDim a(3)
>> q = Split(s, """")
>> WScript.Echo Join(q, vbCrLf)
>>
3545,Albert,
Mathias Albert, Lars-Erik Cederman and Alexander Wendt (eds)
,2010
>> c = Split(q(0), ",")
>> WScript.Echo Join(c, vbCrLf)
>>
3545
Albert

>> a(0) = c(0)
>> a(1) = c(1)
>> a(2) = q(1)
>> a(3) = Mid(q(2), 2)
>> WScript.Echo Join(a, vbCrLf)
>>
3545
Albert
Mathias Albert, Lars-Erik Cederman and Alexander Wendt (eds)
2010
>>

should get you started.
