Dim xml As New Chilkat.Xml()

Dim success As Boolean

success = xml.LoadXmlFile("add_attribute.xml")
If (success <> true) Then
    TextBox1.Text = TextBox1.Text & xml.LastErrorText & vbCrLf
    Exit Sub
End If


'  Add an attribute  a="123" to the root node:
xml.AddAttribute("a","123")

'  Navigate to the 1st child.  After calling FirstChild2,
'  "xml" now references the node with the tag "xyz".
xml.FirstChild2()
xml.AddAttribute("b","456")

'  Navigate to xyz's first child, which is the node having the
'  tag "mmm".
xml.FirstChild2()
xml.AddAttribute("c","789")
xml.AddAttribute("d","000")

'  Revert back to the XML document root node
xml.GetRoot2()

'  Examine the result:
TextBox1.Text = TextBox1.Text & xml.GetXml() & vbCrLf
