Весь файл огромен (2,5 ГБ с большим количеством идентификаторов людей), поэтому мне нужно работа с парсингом, пока что это было редким. То, что я хочу, это фрейм данных, который показывает person id, а также (суммируются, если возможно) trav_time всех ног этого человека. Я изо всех сил пытаюсь получить доступ к этой информации для каждого идентификатора человека.

Я пробовал несколько способов, следующие два, в моем понимании, наиболее близки к возможному решению.

first:

tree = ET.iterparse(gzip.open('V0_1pm/output_plans.xml.gz', 'r'))
traveltimes = defaultdict(list)
for xml_event, elem in tree:
        for person in elem:
            for plan in person:
                for leg in plan:
                    if leg.tag == "trav_time":
                        traveltimes[elem.attrib["trav_time"]]
                    elem.clear()
traveltimes = pd.DataFrame.from_dict(traveltimes, orient='index')                          
traveltimes

second:

tree = ET.iterparse(gzip.open('V0_1pm/output_plans.xml.gz', 'r'))
traveltimes = defaultdict(list)
for xml_event, elem in tree:
    attributes = elem.attrib
    if elem.tag == "trav_time":
            traveltimes[attributes["trav_time"]]
    elem.clear()
traveltimes = pd.DataFrame.from_dict(traveltimes, orient='index')                        
traveltimes

Большое спасибо за помощь и советы!

Answer 1

Попробуйте изменить значение для l oop на следующее, и посмотрите, работает ли оно:

for xml_event, elem in tree:
if elem.tag=='person':        
    items = list(elem)
    target = items[1]        
    if target.attrib['selected']=='yes':
        traveltimes[elem.attrib["id"]]
        legs = list(items[1])
        for leg in legs:
            if leg.tag=='leg':
                traveltimes[leg.attrib["trav_time"]]
    elem.clear()    


traveltimes = pd.DataFrame.from_dict(traveltimes, orient='index')                        
traveltimes

Мой вывод из вашего xml выше:
