Разобрать вывод nmap из vbscript, чтобы вернуть только ОС

Question

Я нашел утилиту под названием nmap, которая запрашивает IP-адрес и возвращает (вероятную) операционную систему. В моих тестах это сработало отлично. Я хотел бы встроить его в vbscript, вызвать его как функцию и вернуть только версию операционной системы.

Образец вывода:

Кажется, это работает очень хорошо

Public function GetOS(ServerName)
    Set objWShell = CreateObject("WScript.Shell") 
    Set objCmd = objWShell.Exec("nmap -O -v " & ServerName) 
    strPResult = objCmd.StdOut.Readall() 
    set objCmd = nothing: Set objWShell = nothing 
    GetOS = "Unknown" 
    if InStr(strPResult,"OS details:")>0 then 
        strTemp1 = split(strPResult,"OS details: ")
        strTemp2 = split(strTemp1(1),vbCrLf)
        GetOS = strTemp2(0)
    end if
End function

wscript.echo GetOS(testserver)
