XdmAttribute

Represents an XML attribute node in the XDM tree.

#XdmAttribute

Namespace: PhoenixmlDb.Xdm.Nodes

Represents an XML attribute node in the XDM tree.

Attribute nodes are associated with an XdmElement but are not children of that element. They exist on a separate axis, accessed through XdmElement.Attributes. An attribute's XdmNode.Parent points to its owning element.

Unlike element and document nodes, an attribute's XdmNode.StringValue is simply its XdmAttribute.Value — no tree traversal is needed.

Namespace declaration attributes (xmlns:*) are not represented as XdmAttribute nodes. They are stored as NamespaceBinding entries in XdmElement.NamespaceDeclarations.
