Module contents

Main entry point for the launch_xml package.

class launch_xml.Entity(*args: Any, **kwargs: Any)

Bases: Entity

Single item in the intermediate XML front_end representation.

assert_entity_completely_parsed()

property children: List[Entity]

Get the Entity’s children.

get_attr(name: str, *, data_type: launch.utilities.type_utils.AllowedTypesType = <class 'str'>, optional: bool = False, can_be_str: bool = True) → launch.utilities.type_utils.AllowedValueType | List[Entity] | None
