Node

Node — Aspose.Note FOSS for Python API Reference

Class: Node

Package: aspose.note Import: from aspose.note import Node

Node is the abstract base class for every element in the OneNote document object model. All concrete node types (Document, Page, Outline, OutlineElement, RichText, Image, AttachedFile, etc.) inherit from Node. You never instantiate Node directly.

Properties

Property	Type	Access	Description
`ParentNode`	`Node \| None`	Read	The parent node in the document tree. `None` for the root `Document` node.
`Document`	`Document \| None`	Read	Walks up the ancestor chain and returns the root `Document`. Returns `None` if this node is not yet attached to a document.
`NodeType`	`NodeType`	Read	Identifies the concrete node type as a `NodeType` enum value.

Methods

Accept(visitor)

node.Accept(visitor: DocumentVisitor) -> None

Dispatches the appropriate VisitXxxStart / VisitXxxEnd methods on the visitor for this node type. Override in subclasses to implement double-dispatch.

NodeType Values

Node.NodeType returns one of the following NodeType enum values:

Value	Description
`NodeType.Document`	Root document node
`NodeType.Page`	OneNote page
`NodeType.Outline`	Positional outline container
`NodeType.OutlineElement`	Leaf content container
`NodeType.RichText`	Styled text block
`NodeType.Image`	Embedded image
`NodeType.Table`	Table
`NodeType.AttachedFile`	Embedded file attachment

Usage Example

Inspect any node’s position in the tree

from aspose.note import Document, RichText

doc = Document("MyNotes.one")
for rt in doc.GetChildNodes(RichText):
    # Every RichText is a Node — access parent and document via Node properties
    print(f"NodeType : {rt.NodeType}")
    print(f"Document : {rt.Document is doc}")
    if rt.ParentNode is not None:
        print(f"Parent   : {rt.ParentNode.NodeType}")
    print()

None-Safety

ParentNode is None only for the root Document. Document is None only when a node has been created but not yet attached to a document tree.
