Examples
The following example creates an attribute that is a namespace declaration and an attribute that is not. It then uses this property to display whether each attribute is a namespace declaration or not.
XNamespace aw = "http://www.adventure-works.com";
XElement root = new XElement(aw + "Root",
new XAttribute(XNamespace.Xmlns + "aw", "http://www.adventure-works.com"),
new XAttribute(aw + "Att", "content")
);
foreach (XAttribute att in root.Attributes()) {
if (att.IsNamespaceDeclaration)
Console.WriteLine("{0} is a namespace declaration", att.Name);
else
Console.WriteLine("{0} is not a namespace declaration", att.Name);
}
Dim root As XElement = <aw:Root xmlns:aw='http://www.adventure-works.com'
aw:Att='content'/>
For Each att As XAttribute In root.Attributes()
If (att.IsNamespaceDeclaration) Then
Console.WriteLine("{0} is a namespace declaration", att.Name)
Else
Console.WriteLine("{0} is not a namespace declaration", att.Name)
End If
Next
This example produces the following output:
{http://www.w3.org/2000/xmlns/}aw is a namespace declaration
{http://www.adventure-works.com}Att is not a namespace declaration
Remarks
Technically, in XML, namespace declarations are not attributes proper. However, this distinction is not normally made by most XML programmers. Instead, because namespace declarations have exactly the same syntax as attributes, most XML programmers think of namespaces as attributes. To simplify the LINQ to XML programming interface, namespaces are represented in the XML tree as attributes. You can use this property to determine if a particular LINQ to XML attribute is really a namespace declaration.
