XdmElement

Represents an XML element node in the XDM tree, including its attributes, children, and namespace declarations.

#XdmElement

Namespace: PhoenixmlDb.Xdm.Nodes

Represents an XML element node in the XDM tree, including its attributes, children, and namespace declarations.

Children: An element's children are stored as a list of NodeId references in XdmElement.Children. Valid child node kinds are element, text, comment, and processing instruction. To access the actual child nodes, resolve each NodeId through the storage layer's node lookup function.

Attributes: Attributes are separate XdmAttribute nodes referenced by XdmElement.Attributes. Per the XDM spec, attributes are not children of the element — they exist on a separate axis. Use the attribute list to enumerate or look up attributes by name.

Namespaces: Each element carries its own XdmElement.NamespaceDeclarations, which record the namespace declarations (xmlns:prefix="uri") that appear on this element. The element's own namespace is stored separately in XdmElement.Namespace.

Construction: Elements are typically created by XmlDocumentParser during XML parsing, or constructed directly using object initializers with the required properties. Use XdmElement.EmptyAttributes, XdmElement.EmptyChildren, and XdmElement.EmptyNamespaceDeclarations for elements that have no attributes, children, or namespace declarations.

#Example

Constructing an element programmatically:

var element = new XdmElement
{
    Id = nodeId,
    Document = documentId,
    Namespace = NamespaceId.None,
    LocalName = "item",
    Prefix = null,
    Attributes = XdmElement.EmptyAttributes,
    Children = XdmElement.EmptyChildren,
    NamespaceDeclarations = XdmElement.EmptyNamespaceDeclarations
};
