如何使用 HtmlAgilityPack 解析 table 中的 <br> 标签？

Question

我有一个 html table，其单元格值由
标记分隔。

<TABLE class=a12 cellSpacing=0 cols=8 cellPadding=0 border=1>

我尝试将 html table 转换为数据table，但单元格值是串联的。

如何解析
标签，以便单元格值可以用逗号分隔而不是组合在一起？

Private Function ParseTable(doc As HtmlDocument) As DataTable
    Dim result As New DataTable()
    Dim TableClassA12 As HtmlNode = doc.DocumentNode.SelectSingleNode("//table[@class='a12']")
    Dim rows = TableClassA12.Descendants("tr")
    Dim header = rows.Skip(1).First()

    For Each column In header.Descendants("td")
        result.Columns.Add(New DataColumn(column.InnerText.Trim, GetType(String)))
    Next

    For Each row In rows.Skip(2)
        Dim data = New List(Of String)()
        For Each column In row.Descendants("td")
            Dim cellText As String = column.InnerText.Trim
            data.Add(cellText)
        Next
        If data.Count > 0 Then
            result.Rows.Add(data.ToArray())
        End If
    Next
    Return result
End Function

为了对现有代码进行最小的更改，您可以 select td 中的 div，然后访问 InnerHtml 以获取内部文本以及 <br> 标签。此时您可以简单地将 <br> 标签替换为逗号 :

For Each column In row.Descendants("td").SelectMany(Function(x) x.Elements("div"))
    Dim cellText As String = column.InnerHtml.Trim.Replace("<br>",",")
    data.Add(cellText)
Next
