#Here is the Python code you requested.

    """Return a list property from child nodes of the current xml node.
    This applies only the simplexml helper, as it assumes __node__, the current
    ElementTree node corresponding to the import record.
    Sample usage for structure:
    <Visit>
    <VisitActivities>
    <Activity>A1</Activity>
    <Activity>A2</Activity>
    </VisitActivities>
    </Visit>
    property: activities
    external_name: VisitActivities # Ignored on import, used on export.
    import_transform: list_from_xml_node(\VisitActivities/Activity\)
    export_transform: child_node_from_list(\Activity\)
    Args:
    xpath: XPath to run on the current node.
    suppress_blank: if True, ndoes with no text will be skipped.
    Returns:
    Transform function which works as described in the args.
