regex - Extract Email address from a table in .HTMLbody

Question

I would like to reply to a webform extracting the email address from the form.

The webform is in a table, thus the ParseTextLinePair() function returns blanks as the email address in the column next to the label.

How can I extract the email address from a webform?

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:UsersReply.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

A picture of the table to clarify.

Have you looked in to Regular Expressions in VBA, I haven't worked on it in while but here is an example.

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 = "[A-Z0-9._%+-]+@[A-Z0-9.-]+.[A-Z]{2,4}"

    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

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