从.HTMLbody中的表中提取电子邮件地址

Question

我想回复从表单中提取电子邮件地址的网络表单。

Webform在表中，因此ParseTextLinePair（）函数返回空白作为标签旁边列中的电子邮件地址。

如何从网络表格中提取电子邮件地址？

Sub ReplywithTemplatev2() 
Dim Item As Outlook.MailItem 
Dim oRespond As Outlook.MailItem 

'Get Email 
    Dim intLocAddress As Integer 
    Dim intLocCRLF As Integer 
    Dim strAddress As String 

Set Item = GetCurrentItem() 

If Item.Class = olMail Then 

     ' find the requestor address 
     strAddress = ParseTextLinePair(Item.Body, "Email-Adresse des Ansprechpartners *") 


' This sends a response back using a template 
Set oRespond = Application.CreateItemFromTemplate("C:\Users\Reply.oft") 

With oRespond 
    .Recipients.Add Item.SenderEmailAddress 
    .Subject = "Your Subject Goes Here" 
    .HTMLBody = oRespond.HTMLBody & vbCrLf & _ 
       "---- original message below ---" & vbCrLf & _ 
       Item.HTMLBody & vbCrLf 

' includes the original message as an attachment 
    ' .Attachments.Add Item 

    oRespond.To = strAddress 

' use this for testing, change to .send once you have it working as desired 
    .Display 


End With 

End If 
Set oRespond = Nothing 

End Sub

Function GetCurrentItem() As Object 
    Dim objApp As Outlook.Application 

    Set objApp = Application 
    On Error Resume Next 
    Select Case TypeName(objApp.ActiveWindow) 
     Case "Explorer" 
      Set GetCurrentItem = objApp.ActiveExplorer.Selection.Item(1) 
     Case "Inspector" 
      Set GetCurrentItem = objApp.ActiveInspector.CurrentItem 
    End Select 

    Set objApp = Nothing 
End Function

Function ParseTextLinePair(strSource As String, strLabel As String) 
    Dim intLocLabel As Integer 
    Dim intLocCRLF As Integer 
    Dim intLenLabel As Integer 
    Dim strText As String 

    ' locate the label in the source text 
    intLocLabel = InStr(strSource, strLabel) 
    intLenLabel = Len(strLabel) 
     If intLocLabel > 0 Then 
     intLocCRLF = InStr(intLocLabel, strSource, vbCrLf) 
     If intLocCRLF > 0 Then 
      intLocLabel = intLocLabel + intLenLabel 
      strText = Mid(strSource, _ 
          intLocLabel, _ 
          intLocCRLF - intLocLabel) 
     Else 
      intLocLabel = Mid(strSource, intLocLabel + intLenLabel) 
     End If 
    End If 
    ParseTextLinePair = Trim(strText) 
End Function 

表中的的图象，以澄清。

你有没有在看正则表达式在VBA，我没有工作就可以了，而在这里却是一个例子。

Option Explicit 
Sub Example() 
    Dim Item As MailItem 
    Dim RegExp As Object 
    Dim Search_Email As String 
    Dim Pattern As String  
    Dim Matches As Variant 

    Set RegExp = CreateObject("VbScript.RegExp") 

    Pattern = "\b[A-Z0-9._%+-][email protected][A-Z0-9.-]+\.[A-Z]{2,4}\b" 

    For Each Item In ActiveExplorer.Selection 

     Search_Email = Item.body 

     With RegExp 
      .Global = False 
      .Pattern = Pattern 
      .IgnoreCase = True 
      Set Matches = .Execute(Search_Email) 
     End With 

     If Matches.Count > 0 Then 
      Debug.Print Matches(0) 
     Else 
      Debug.Print "Not Found " 
     End If 

    Next 

    Set RegExp = Nothing 

End Sub 

或者Pattern = "(\S*@\w+\.\w+)"或者"(\w+(?:\W+\w+)*@\w+\.\w+)"
