从特定节点检索特定值-VB.NET XML HTTP GET

Question

I have a program I am writing that calls a Feed using HTTP GET that returns XML. 我有一个正在编写的程序，该程序使用返回XML的HTTP GET调用Feed。

I have written code to be able to read each Element and their Values but I only wish to retrieve specific Element Values to specific variables. 我已经编写了能够读取每个元素及其值的代码，但我只希望将特定的元素值检索到特定的变量。

I could use nested If statements to check for the 'reader.value' and then put it to the relevant variable but feel this seems cumbersome and would like to have a better understanding. 我可以使用嵌套的If语句来检查“ reader.value”，然后将其放入相关变量，但是感觉这似乎很麻烦，并且希望有一个更好的理解。

This is my current code: 这是我当前的代码：

Const URLString As String = "https://geturl"
    Dim reader As XmlTextReader = New XmlTextReader(URLString)

    Do While (reader.Read())
        Select Case reader.NodeType
            Case XmlNodeType.Element 'Display beginning of element.
                Console.Write("<" + reader.Name)
                If reader.HasAttributes Then 'If attributes exist
                    While reader.MoveToNextAttribute()
                        'Display attribute name and value.
                        Console.Write(" {0}='{1}'", reader.Name, reader.Value)
                        MsgBox(reader.Value)
                    End While
                End If
                Console.WriteLine(">")
            Case XmlNodeType.Text 'Display the text in each element.
                Console.WriteLine(reader.Value)
            Case XmlNodeType.EndElement 'Display end of element.
                Console.Write("</" + reader.Name)
                Console.WriteLine(">")
        End Select
    Loop

This is the information that is returned: 这是返回的信息：

<result id="4198608" generated="1399463340" mode="live" account_id="428">
<vrm>GY08OJB</vrm>
<make>AUDI</make>
<model>A6 SE TDI</model>
<colour>BLACK</colour>
<body>ESTATE</body>
<doors>5 DOORS</doors>
<engine_size>1968</engine_size>
<fuel>HEAVY OIL</fuel>
</result>

I wish to return each individual node to an individual record so I can return it to some textboxes. 我希望将每个单独的节点返回到一个单独的记录，以便可以将其返回到一些文本框。

Cheers :/ 欢呼声：/

Since you use VB.Net you can go the easy route and use XML literals: 由于使用的是VB.Net，因此可以轻松进行操作并使用XML文字：

' Load your xml into an XElement '
Dim xml = <result id="4198608" generated="1399463340" mode="live" account_id="428">
                <vrm>GY08OJB</vrm>
                <make>AUDI</make>
                <model>A6 SE TDI</model>
                <colour>BLACK</colour>
                <body>ESTATE</body>
                <doors>5 DOORS</doors>
                <engine_size>1968</engine_size>
                <fuel>HEAVY OIL</fuel>
            </result>


Dim vrm = xml.<vrm>.Value      ' is now GY08OJB   '
Dim make = xml.<make>.Value    ' is now AUDI      '
Dim model = xml.<model>.Value  ' is now A6 SE TDI '

I used the following for anyone that is interested: 我对感兴趣的任何人使用了以下内容：

   Dim strReg
    Dim doc As XmlDocument = New XmlDocument()

doc.Load(myURL)

        doc.SelectSingleNode("<root>/<node>").InnerText

Cheers. 干杯。
