如何用@替换'at'

Question

我有大约17k的电子邮件包含订单,新闻,联系人等,可以追溯到11年前.

用户的电子邮件地址已经粗制滥造加密,通过改变停止抓取工具和垃圾邮件@要么*@*或'at'.

我正在尝试创建一个逗号分隔列表来构建我们用户的数据库.

该代码适用于编写文件和循环文件夹,因为如果我将发件人的电子邮件地址写入我当前正在使用电子邮件正文的文件,那么它打印正常.

问题是,Replaces没有改变*at*等@.

1. 首先,为什么不呢？
2. 我有更好的方式做这个整体吗？

Private Sub Form_Load()

   Dim objOutlook As New Outlook.Application
   Dim objNameSpace As Outlook.NameSpace
   Dim objInbox As MAPIFolder
   Dim objFolder As MAPIFolder
   Dim fldName As String

   fldName = "TEST"

   ' Get the MAPI reference

   Set objNameSpace = objOutlook.GetNamespace("MAPI")

   ' Pick up the Inbox

   Set objInbox = objNameSpace.GetDefaultFolder(olFolderInbox)

   'Loop through the folders under the Inbox
   For Each objFolder In objInbox.Folders
       RecurseFolders fldName, objFolder
   Next objFolder

End Sub

Public Sub RecurseFolders(targetFolder As String, currentFolder As MAPIFolder)
   If currentFolder.Name = targetFolder Then
       GetEmails currentFolder
   Else
       Dim objFolder As MAPIFolder
       If currentFolder.Folders.Count > 0 Then
           For Each objFolder In currentFolder.Folders
               RecurseFolders targetFolder, objFolder
           Next
       End If
     End If
End Sub

Sub WriteToATextFile(e As String)
    MyFile = "c:\" & "emailist.txt"
    'set and open file for output
    fnum = FreeFile()
    Open MyFile For Append As fnum
    Print #fnum, e; ","
    Close #fnum
End Sub

Sub GetEmails(folder As MAPIFolder)
    Dim objMail As MailItem

    ' Read through all the items
    For i = 1 To folder.Items.Count
        Set objMail = folder.Items(i)
        GetEmail objMail.Body              
    Next i

End Sub

Sub GetEmail(s As String)
    Dim txt = s
    Do Until InStr(txt, "@") <= 0
        Dim tleft As Integer
        Dim tright As Integer
        Dim start As Integer
        Dim text As String
        Dim email As String

        text = Replace(text, " at ", "@", VbCompareMethod.vbTextCompare)
        text = Replace(text, "'at'", "@", VbCompareMethod.vbTextCompare)
        text = Replace(text, "*at*", "@", VbCompareMethod.vbTextCompare)
        text = Replace(text, "*at*", "@", VbCompareMethod.vbTextCompare)

        text = Replace(text, "<", " ", VbCompareMethod.vbTextCompare)
        text = Replace(text, ">", " ", VbCompareMethod.vbTextCompare)
        text = Replace(text, ":", " ", VbCompareMethod.vbTextCompare)

        'one two ab@bd.com one two
        tleft = InStr(text, "@") '11

        WriteToATextFile Str(tleft)
        WriteToATextFile Str(Len(text))

        start = InStrRev(text, " ", Len(text) - tleft)
        'WriteToATextFile Str(start)
        'WriteToATextFile Str(Len(text))
        'start = Len(text) - tleft
        text = left(text, start)
        'ab@bd.com one two

        tright = InStr(text, " ") '9
        email = left(text, tright)
        WriteToATextFile email

        text = right(text, Len(text) - Len(email))
        GetEmail txt
    Loop
End Sub

使用正则表达式(正则表达式)怎么样？

就像是:

Public Function ReplaceAT(ByVal sInput as String)
     Dim RegEx As Object
     Set RegEx = CreateObject("vbscript.regexp")
     With RegEx
      .Global = True
      .IgnoreCase = True
      .MultiLine = True
      .Pattern = "( at |'at'|<at>)"
     End With
     ReplaceAT = RegEx.Replace(sInput, "@")
     Set RegEx = Nothing
End Function

只需将regexp替换为您可能遇到的每种情况.

我已经对此进行了破解，以提取电子邮件，例如下面的示例，它将把下面示例消息中黄色的三个电子邮件地址提取到一个 csv 文件中

1. 所有有效的电子邮件都会写入 csv 文件Set objTF = objFSO.createtextfile("c:\myemail.csv")
2. 此代码扫描名为“我删除了测试和简单性的递归部分”的文件夹中的所有电子邮件tempInbox
3. 有四种字符串操作
4. 该行将任何非打印空格转换为正常空格strMsgBody = Replace(strMsgBody, Chr(160), Chr(32)（不太可能，但在我的测试中发生了）
5. Regex1 将任何“at”或“ at ”等转换为“@” "(\s+at\s+|'at'|<at>|\*at\*|at)"
6. Regex2 将任何“点”或“点”等转换为“。” "(\s+dot\s+|'dot'|<dot>|\*dot\*|dot)"
7. Regex3 将任何“<”>”或“:”转换为“” .Pattern = "[<:>]"
8. Regex4从电子邮件正文中提取任何有效的电子邮件

9. 任何有效的电子邮件都会使用以下命令写入 csv 文件objTF.writeline objRegM

   

代码如下

Public Test()
Dim objOutlook As New Outlook.Application
Dim objNameSpace As Outlook.NameSpace
Dim objFolder As MAPIFolder
Dim strfld As String
Dim objRegex As Object
Dim objRegMC As Object
Dim objRegM As Object
Dim objFSO As Object
Dim oMailItem As MailItem
Dim objTF As Object
Dim strMsgBody As String    
Set objRegex = CreateObject("vbscript.regexp")
Set objFSO = CreateObject("scripting.filesystemobject")
Set objTF = objFSO.createtextfile("c:\myemail.csv")

With objRegex
    .Global = True
    .MultiLine = True
    .ignorecase = True
    strfld = "temp"
    'Get the MAPI reference
    Set objNameSpace = objOutlook.GetNamespace("MAPI")
    'Pick up the Inbox
    Set objFolder = objNameSpace.GetDefaultFolder(olFolderInbox)
    Set objFolder = objFolder.Folders(strfld)
    For Each oMailItem In objFolder.Items
        strMsgBody = oMailItem.Body
        strMsgBody = Replace(strMsgBody, Chr(160), Chr(32))
        .Pattern = "(\s+at\s+|'at'|<at>|\*at\*|at)"
        strMsgBody = .Replace(strMsgBody, "@")
        .Pattern = "(\s+dot\s+|'dot'|<dot>|\*dot\*|dot)"
        strMsgBody = .Replace(strMsgBody, ".")
        .Pattern = "[<:>]"
        strMsgBody = .Replace(strMsgBody, vbNullString)
        .Pattern = "[\w-\.]{1,}\@([\da-zA-Z-]{1,}\.){1,}[\da-zA-Z-]{2,3}"
        If .Test(strMsgBody) Then
            Set objRegMC = .Execute(strMsgBody)
            For Each objRegM In objRegMC
                objTF.writeline objRegM
            Next
        End If
    Next
End With
objTF.Close
End Sub
