# Returns deep copy of body in XML, using passed in name
def find_body_by_name(xml_root, target_name=None):
    if target_name is not None:
        for body in xml_root.findall(".//body"):
            if body.attrib.get("name") == target_name:
                return copy.deepcopy(body)
    worldbody = xml_root.find(".//worldbody")
    if worldbody is not None and len(worldbody) > 0:
        for body in worldbody.findall("body"):

    return None

Hey guys, I had a question about this, specifically the following part:

for body in worldbody.findall("body"):      
            return copy.deepcopy(body)

why are you returning just the first element and not all of them?
