Hello, I'm trying to get names of attributes nodes of an XML file..i'm able to read nodes and attributes value but not names.
In this xml example:

XML

<?xml version="1.0" encoding="UTF-8"?>
-<Root>
-<body surname="Rott" name="Pig">
<city>London</city>
</body>
-<body surname="Lip" name="Jack">
<city>Los Angeles</city>
</body>
-<body colorB="White" colorA="Yellow">
<city>Rome</city>
</body>
</Root>

I'm trying to get "surname", "name", "colorB", "colorA" etc.

I do this vb.net example but I cannot get attribute (need something like a reader.GetNameAttribute command)? Does it exists?

What I have tried:

OpenFileDialog1.Multiselect = False
OpenFileDialog1.ShowDialog()
Dim fileName As String = Path.GetFileName(OpenFileDialog1.FileName)
Dim filePath As String = OpenFileDialog1.FileName
Me.Text = filePath
Dim docXML As New XmlDocument
docXML.Load(filePath)
Dim reader As XmlNodeReader = New XmlNodeReader(docXML)


While reader.Read

    Dim lettura = reader.NodeType
    Dim valueA As String
    Dim attr_name As String = "none"



    valueA = reader.Name
    If reader.HasAttributes Then

        Dim conteggio As Integer = reader.AttributeCount
        For x = 0 To conteggio - 1
            MsgBox("Node is: " + valueA + " and has an attribute named: " + attr_name + " = " + reader.GetAttribute(x))
        Next
    End If



End While

Hello,

you could be using the class XmlNode see here: XmlNode Class (System.Xml) | Microsoft Learn[^]

Refactoring a bit your code like that:

While reader.Read

    Dim lettura = reader.NodeType
    Dim valueA As String
    Dim attr_name As String = "none"

    valueA = reader.Name
    If reader.HasAttributes Then
        Dim node As XmlNode = docXML.ReadNode(reader)
        Console.Write("Node is: " & valueA)

        If node.Attributes IsNot Nothing Then
            For Each attribute As XmlAttribute In node.Attributes
                Console.Write(" Attribute Name: {0}, Value: {1}.", attribute.Name, attribute.Value)
            Next
        End If
        Console.WriteLine()
    End If
End While

Console.Read()

gives you this output:

Node is: xml
Node is: body Attribute Name: surname, Value: Rott. Attribute Name: name, Value: Pig.
Node is: body Attribute Name: colorB, Value: White. Attribute Name: colorA, Value: Yellow.

Good luck!
