Attr

Attr

Overview

Attr is a class in Aspose.Html FOSS for Python. Inherits from: Node.

An attribute attached to an Element.

This class provides 23 methods for working with Attr objects in Python programs. Available methods include: __init__, add_event_listener, append_child, clone_node, compare_document_position, contains, dispatch_event, get_feature, get_root_node, get_user_data, has_child_nodes, insert_before, and 11 additional methods. All public members are accessible to any Python application after installing the Aspose.Html FOSS for Python package. Properties: child_nodes, first_child, is_connected, last_child, local_name, name, and 14 more.

Methods

Signature	Description
`__init__(name: str, value: str, owner_element: Element \| None, owner_document: Document \| None, namespace_uri: str \| None, local_name_ns: str \| None)`	Calls init(name, value, owner_element, owner_document, namespace_uri, local_name_ns) on this Attr instance.
`get_root_node(composed: bool)` → `"Node"`	Return the root of the node’s tree.
`has_child_nodes()` → `bool`	Return whether this node has at least one direct child node.
`lookup_namespace_uri(prefix: str \| None)` → `str \| None`	Return the effective namespace URI for prefix in this node context.
`lookup_prefix(namespace_uri: str \| None)` → `str \| None`	Return the effective prefix for namespace_uri in this node context.
`is_default_namespace(namespace_uri: str \| None)` → `bool`	Return whether namespace_uri equals this node context default namespace.
`is_supported(feature: str, version: str \| None)` → `bool`	Return legacy feature-probe compatibility status.
`get_feature(feature: str, version: str \| None)` → `object \| None`	Return the legacy feature object for a probe, or `None`.
`set_user_data(key: str, data: object \| None, handler: object \| None)` → `object \| None`	Store or clear node-local user data and return the previous value.
`get_user_data(key: str)` → `object \| None`	Return node-local user data for key or `None` when absent.
`append_child(node: Node)` → `Node`	Append node as the last child of this node.
`insert_before(node: Node, reference: Node \| None)` → `Node`	Insert node before reference in the child list.
`remove_child(node: Node)` → `Node`	Remove node from the child list and return it.
`replace_child(new_child: Node, old_child: Node)` → `Node`	Replace old_child with new_child.
`clone_node(deep: bool)` → `Node`	Return a copy of this node.
`normalize()`	Put this node and its entire subtree into normalized form.
`contains(other: Node \| None)` → `bool`	Return `True` if other is an inclusive descendant of this node.
`compare_document_position(other: "Node")` → `int`	Return a bitmask describing the position of other relative to this node.
`is_equal_node(other: Node \| None)` → `bool`	Return `True` if other has the same structure as this node.
`is_same_node(other_node: Node \| None)` → `bool`	Return `True` when other_node is this node instance.
`add_event_listener(type: str, listener: Callable, capture: bool, once: bool)`	Register listener for events of type.
`remove_event_listener(type: str, listener: Callable, capture: bool)`	Deregister a previously-registered listener.
`dispatch_event(event: "Event")` → `bool`	Dispatch event through the ancestor tree.
