Excel VBA - 获取网站上的所有 href 链接

Question

您好，希望有人能帮助我。 在此示例链接中:https://www.academiadasapostas.com/stats/competition/brasil/26

我想获取所有作为“VS”目标的href链接。 我正在尝试这样的例子:

Sub ScrapeScores()

Dim IE As New SHDocVw.InternetExplorer
Dim HTMLDoc As MSHTML.HTMLDocument
Dim HTMLTables As MSHTML.IHTMLElementCollection
Dim HTMLTable As MSHTML.IHTMLElement
Dim HTMLDiv As MSHTML.IHTMLElement
Dim TableSection As MSHTML.IHTMLElement
Dim TableRow As MSHTML.IHTMLElement
Dim TableCell As MSHTML.IHTMLElement
Dim RowText As String



IE.Visible = True
IE.navigate "https://www.academiadasapostas.com/stats/competition/brasil/26"

Do While IE.readyState <> READYSTATE_COMPLETE Or IE.Busy
Loop

Set HTMLDoc = IE.document
Set HTMLDiv = HTMLDoc.getElementById("competition-round-group-0")
Set HTMLTables = HTMLDiv.getElementsByTagName("a")

For Each HTMLTable In HTMLTables
    Debug.Print HTMLTable.ID, "&", HTMLTable.className
    
    For Each TableSection In HTMLTable.Children
        Debug.Print , TableSection.tagName
        
    Next TableSection
    
Next HTMLTable


End Sub

但没有成功。我想我可以将 CSS 与 SelectorAll 一起使用，对吧？由于 IE 即将消失，最好使用 CSS 来代替。

提前感谢您的回答。

Answer 1

您可以使用以下 css 模式 querySelectorAll .competition-rounds td:nth-child(4) > a。循环返回的nodeList并从每个节点中提取href。这将选择该表中的第 4 列，然后是子 a 标记，在循环期间从中提取 href 属性。

        While .Busy Or .readyState <> READYSTATE_COMPLETE: DoEvents: Wend
        
        Set nodeList = ie.Document.querySelectorAll(".competition-rounds td:nth-child(4) > a")
        
        Dim i As Long
        
        For i = 0 To nodeList.length - 1
          
            Debug.Print nodeList.Item(i).href

        Next
        
        Stop

        .Quit
    End With
End Sub
