如何从 for each 具有正则表达式匹配的循环中获取所有值并将其显示在电子邮件中？

Question

现有电子邮件的示例内容：

01131004378-项目 1
01121109880-项目 2
01983345661-项目 3

宏应根据正则表达式模式从现有电子邮件中提取数字，然后将其显示在新的电子邮件中。

Sub GetValue()
    
    Dim olMail As Outlook.MailItem
    Dim Selection As Selection
    Dim obj As Object

    Set olMail = Application.ActiveExplorer().Selection(1)
    Set Selection = ActiveExplorer.Selection

    For Each obj In Selection

    Set objMsg = Application.CreateItem(olMailItem)
    Dim rxp13 As New RegExp
    rxp13.Pattern = "(\d{11}(?=[-]))"
    rxp13.Global = True
    
    Dim m13 As Match, c13 As MatchCollection
    
    Set c13 = rxp13.Execute(olMail.Body)
    
    Dim item As String
    
    For Each m13 In c13
        item = m13.SubMatches(0)
    Next
    

    '......DISPLAY EMAIL ......
    '--------------------------
    With objMsg
        .To = "mail@test.com"
        .Subject = obj.Subject
        .HTMLBody = _
        "<HTML><BODY>" & _
        "<div style='font-size:10pt;font-family:Verdana'>" & _
        "<table style='font-size:10pt;font-family:Verdana'>" & _
        "<tr><td><strong>ITEMS</strong></td></tr>" & _
        "<tr>" & _
        "<td>" & item & "</td>" & _
        "</tr>" & _
        "</table>" & _
        "</div>" & _
        "</BODY></HTML>"
        
        .Display
        
    End With
    Set objMsg = Nothing
    '----------------------------------------------------------------
    Next
End Sub

预期结果：

01131004378
01121109880
01983345661

我只得到最后一个：

01983345661

如何显示 for each 循环中的所有值并将其放入“”& item &“”？

Answer 1

这是因为您的代码正在替换以前的 item 值。
试试这个代码：

Sub test1()
    Const txt = "01131004378-Item1" & vbLf & "01121109880-Item2" & vbLf & "01983345661-Item3"
    Const pattern = "<td>#</td>"
    
    Dim rxp13 As New RegExp, m13 As Match, c13 As MatchCollection, item As String
    rxp13.pattern = "\d{11}(?=[-])"
    rxp13.Global = True
    
    Set c13 = rxp13.Execute(txt)
    If c13.Count Then
        For Each m13 In c13
            item = item & vbLf & Replace(pattern, "#", m13)
        Next
        item = Mid(item, 2)
        Debug.Print _
            "<HTML><BODY>" & vbLf & _
            "<div style='font-size:10pt;font-family:Verdana'>" & vbLf & _
            "<table style='font-size:10pt;font-family:Verdana'>" & vbLf & _
            "<tr><td><strong>ITEMS</strong></td></tr>" & vbLf & _
            "<tr>" & vbLf & _
            item & vbLf & _
            "</tr>" & vbLf & _
            "</table>" & vbLf & _
            "</div>" & vbLf & _
            "</BODY></HTML>"
    End If
End Sub

输出：

<HTML><BODY>
<div style='font-size:10pt;font-family:Verdana'>
<table style='font-size:10pt;font-family:Verdana'>
<tr><td><strong>ITEMS</strong></td></tr>
<tr>
<td>01131004378</td>
<td>01121109880</td>
<td>01983345661</td>
</tr>
</table>
</div>
</BODY></HTML>
