使用ElementTree检索信息

Question

我尝试使用ElementTree检索信息。我成功地检索了许多属性，但处理过程可能因为缺少信息而停止。它会显示以下错误消息：

xml.etree.ElementTree.ParseError: no element found: line 1, column 0

下面是我使用的代码：

import xml.etree.ElementTree

MyosmID = str(id_cinema)
r = requests.get("https://www.openstreetmap.org/api/0.6/node/"+MyosmID)
root = xml.etree.ElementTree.fromstring(r.content)

for child in root.iter('tag'):
    if child.attrib['k'] == 'website':
        website = child.attrib['v']
    if child.attrib['k'] == 'wikidata':
        wikidata = child.attrib['v']

如何解决此错误情况？

Answer 1

我将此代码添加到我的代码中，问题就解决了：

    MyosmID = str(id_cinema)
try : 
    r = requests.get("https://www.openstreetmap.org/api/0.6/node/"+MyosmID)
    r.raise_for_status()
    root = xml.etree.ElementTree.fromstring(r.content)
    
    fromstring: print(r.status_code) 
    
    for child in root.iter('tag'):
        if child.attrib['k'] == 'website':
            website = child.attrib['v']
        if child.attrib['k'] == 'wikidata':
            wikidata = child.attrib['v']
except Exception:
    pass
