整個文件很大（2.5gb 有更多的人 id），這就是為什么我需要進行解析，到目前為止這已經是 iterparse。 我想要的是一個數據框，它顯示了這個人的所有腿的person id以及（如果可能的話） trav_time 。 我正在努力為每個人的 ID 訪問這些信息。
我嘗試了多種方法，以下兩種根據我的理解最接近可能的解決方案。
第一的：
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
第二：
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
非常感謝您的幫助和提示！

嘗試將您的 for 循環更改為以下內容，看看它是否有效：
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
我的輸出，來自上面的 xml：
10007071
00:11:55
00:13:13
