將具有多個表的XML導入VB.NET

所以我有以下.XML文件...

我希望將其導入VB.NET。 我發現以下MSDN文章https://msdn.microsoft.com/zh-cn/library/ekw4dh3f.aspx，但是示例.XML文件僅包含一個表，因此將其應用於文件時會出錯。

有人可以幫我解決如何將此文件導入數據集。

稍后，我將需要弄清楚如何在更新.XML時更新數據集（我別無選擇，我唯一的數據源就是.XML），但現在我會很高興能夠導入文件。

@jdweng是正確的，這里有一些代碼可幫助您探索導入的內容：

    Dim ds As New DataSet
    Dim sr As New StringReader(sPostXMLData)
    ds.ReadXml(sr)
    For Each t As DataTable In ds.Tables
        Debug.Print(t.TableName)
    Next

沒用處。 查看更多用於分析數據的XML專用工具。
