get_ancestor method

get_ancestor(ancestor_type)

Gets the first ancestor of the specified object type.

def get_ancestor(self, ancestor_type: object):
    ...

Parameter	Type	Description
ancestor_type	object	The object type of the ancestor to retrieve.

Remarks

The ancestor type matches if it is equal to ancestorType or derived fromancestorType.

Returns

The ancestor of the specified type or None if no ancestor of this type was found.

get_ancestor(ancestor_type)

Gets the first ancestor of the specified NodeType.

def get_ancestor(self, ancestor_type: aspose.words.NodeType):
    ...

Parameter	Type	Description
ancestor_type	NodeType	The node type of the ancestor to retrieve.

Returns

The ancestor of the specified type or None if no ancestor of this type was found.

Examples
