我正在寻找的是拥有一个人的所有person id值的列表或数据框，这些人在plan selected="yes"中至少有一个leg和mode="pt"。
这是没有任何输出的方法：
import gzip
import xml.etree.cElementTree as ET
import pandas as pd
from collections import defaultdict
file = 'output_plans.xml.gz'
data = gzip.open(file, 'r')
root = ET.parse(data).getroot()
d = defaultdict(list)
for ent in root.findall('./person./person'):
for anoda in ent.findall('plan[@selected="yes"]/leg[@mode="pt"]'):
d['id'].append(ent.get('id'))
ids=pd.DataFrame(d)
ids
您的代码中的问题是您正在使用findall()的'./person./person'中的路径。您只需要使用'./person'和另一件事，就无需使用内部循环。如果条件为find()，则只能使用find('plan[@selected="yes"]/leg[@mode="pt"]')方法。
