regex - 使用宏从 Microsoft Outlook 邮件中提取所有 IP 地址

Question

我一直在研究如何从 Outlook 邮件中提取所有 IP 地址并将其复制到 Excel 电子表格。我有一个工作示例，用于从 OL 消息中提取 1 个 IP 地址并将其复制到 Excel 单元格。目前它每个单元复制 1 个八位字节，但理想情况下我需要 1 个单元中的 IP 地址。

我还需要宏来检查邮件的完整正文并提取所有 IP 地址。消息中可能有 1 到 100 个 IP 地址。

enviro = CStr(Environ("USERPROFILE"))
'the path of the workbook

     On Error Resume Next
     Set xlApp = GetObject(, "Excel.Application")
     If Err <> 0 Then

    ' \w* = match alphanumeric

    With Reg1

Answer 1

您的模式实际上匹配完整的 IPv4 地址，您可能会在 regex demo 中看到它。这意味着，您只需要获取整个比赛，而不是子比赛。

此外，要获得多次出现(在 regex101.com，请参阅 g 修饰符)，您需要设置 Reg1.Global = True。

所以，使用

With Reg1
    .Pattern = "((25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?))"
    .Global = True
End With

然后

For Each M In M1
    vText = Trim(M.Value)
Next

其余代码并不难调整。
