用Python名称空间解析XML

我想使用开放数据，xml存储在这里：

在这个论坛的帮助下，我编写了代码

from lxml import etree
from urllib.request import urlopen


root = etree.parse(urlopen(url)).getroot()


ns = { 'd': 'http://datex2.eu/schema/2/2_0' }

parking_area = root.xpath('//d:parkingAreaStatus', namespaces=ns)
parking_facility = root.xpath('//d:parkingFacilityStatus', namespaces=ns)

for pa in parking_area:
    area_ref = pa.find('d:parkingAreaReference', ns)
    ParkingspaceList.append(str((area_ref.get('id'))))


for pf in parking_facility:
    facility_ref = pf.find('d:parkingFacilityReference', ns)
    ParkingspaceList.append(str((facility_ref.get('id'))))

这似乎对pa有效，但对于pf，我收到了一条失败消息：

ParkingspaceList.appendstrfacility\u ref.获取“id” AttributeError:“非类型”对象没有属性“get”

有什么建议吗

致意

在名称相同的parkingFacilityStatus元素中有parkingFacilityStatus元素，这相当令人困惑：

<parkingFacilityStatus>
    …
    <parkingFacilityReference targetClass="ParkingFacility" id="24278[Karstadt]" version="1.0"/>
    <parkingFacilityStatus>closed</parkingFacilityStatus>
    …
</parkingFacilityStatus>

而且很有效。

@theamokdog很高兴它起到了作用！

    <parkingFacilityStatus>closed</parkingFacilityStatus>

for pf in parking_facility:
    facility_ref = pf.find('d:parkingFacilityReference', ns)
    if facility_ref is not None:
        ParkingspaceList.append(str((facility_ref.get('id'))))
