如何使用 VBA 跳过缺少 html 标记的 Excel 行

Question

本网站列出了 15 个对象，每个对象的照片下方都有一个 link。第 6 个对象有 none。当使用我的代码提取和传输内容时，缺少的 html-href 不会被跳过，在 Excel 中，14 个 href 列在彼此下方（第 6 个单元格应保持为空或“无文档”），但最后一个单元格确实如此（&错误，因为 14<=>15）。不幸的是，我必须保留我的代码结构，只需要一个循环或条件来完成它。有人有什么想法吗？谢谢

我的不完整代码：

Public Sub GetData()

    Dim html As New HTMLDocument
    Dim elmt01 As Object, elmt02 As Object
    Dim y As Long
    Dim xURL As String

    Set html = New MSHTML.HTMLDocument
    xURL = "https://immobilienpool.de/suche/immobilien?page=1"
    
With CreateObject("MSXML2.XMLHTTP.6.0")
    .Open "GET", xURL, False
    .send
     html.body.innerHTML = .responseText
End With

Set elmt01 = html.querySelectorAll("li[class*='contentBox']")    '15 items
Set elmt02 = html.querySelectorAll("li a[title*='zusätzliche']") '14 hrefs

For y = 0 To elmt01.Length - 1

  If InStr(elmt02, "pdf") Then  'better: If elmt02 exists in elmt01 then...
    ActiveSheet.Cells(y + 1, 2) = elmt02.Item(y).href
  Else
    ActiveSheet.Cells(y + 1, 2) = "No document"
  End If

Next

End Sub

以下脚本应该可以解决您遇到的问题。我不得不修改您的代码以跳过空白行。希望您能遵守当前版本：

Public Sub GetData()
    Dim Html As HTMLDocument, HTMLDoc As HTMLDocument
    Dim oPdfLink As Object, xURL As String, I As Long

    Set Html = New MSHTML.HTMLDocument
    Set HTMLDoc = New MSHTML.HTMLDocument
    
    xURL = "https://immobilienpool.de/suche/immobilien?page=1"
    
    With CreateObject("MSXML2.XMLHTTP.6.0")
        .Open "GET", xURL, False
        .send
         Html.body.innerHTML = .responseText
    End With

    With Html.querySelectorAll("li[class*='contentBox']")
        For I = 0 To .Length - 1
            HTMLDoc.body.innerHTML = .item(I).outerHTML
            Set oPdfLink = HTMLDoc.querySelector("a[title*='zusätzliche']")
            
            If Not oPdfLink Is Nothing Then
                ActiveSheet.Cells(I + 1, 2) = oPdfLink.href
            Else:
                ActiveSheet.Cells(I + 1, 2) = "No document"
            End If
        Next I
    End With
End Sub
