使用 VB.net 和 Xmldocument 解析 XML

Question

我有几个 xml 文档正在用 VB.Net 解析。除了这一个，我能够解析所有这些。

我想从 type="route_number" 的 "incoming_did_route" 节点提取 "number"、"note" 和 "name" 的值。他们我想从子节点"extension"

中拉取"account_id"的值

下面是我正在尝试使用的 vb.net 代码：

 Dim doc As New XmlDocument()
    doc.Load("filename.xml")
    Dim nodes As XmlNodeList = doc.SelectNodes("/response/result/incoming_did_routes/incoming_did_route/*")
    Dim name As String = "", number As String = "", note As String = "", account_id As String = ""
    For Each node As XmlNode In nodes
        number = node.Attributes.GetNamedItem("number").Value
        name = node.Attributes.GetNamedItem("name").Value
        note = node.Attributes.GetNamedItem("note").Value
        account_id = node.Attributes.GetNamedItem("account_id").Value
    Next

如果我注释掉号码、姓名和备注，它将拉取 account_id。但我不知道如何获取其他值并将其缩小到仅 type="route_number".

这是 xml 文件中保存的内容：

<response method="switchvox.incomingDidRoutes.getList">
  <result>
    <incoming_did_routes total_items="4">
        <incoming_did_route type="route_number" priority="6" any_provider="1" force_fax="0" number="0000" call_type="2" note="jane doe" name="000-000-0000" id="49">

        <incoming_did_route type="catchall_unknown_route" priority="20000" id="1" action="busy"/>
    </incoming_did_routes>
  </result>
</response>

非常感谢任何帮助！
