Hi,
你好，
I am trying to parse above xml file using Python BeautifulSoup and lxml.我正在尝试使用 Python BeautifulSoup 和 lxml 解析以上 xml 文件。 Usually I navigate to the element using '.'.通常我使用'.'导航到元素。 eg例如
from bs4 import BeautifulSoup
with open('sample.xml', 'r') as xml_file:
soup = BeautifulSoup(xml_file, 'lxml')
for item in soup.body.response.policy.panorama.address.find('entry'):
<some code action>
My problem is with navigating via above for tags like '' and ''.我的问题是通过上面导航“”和“”等标签。 Since there is "-" in the tag name, the "."由于标签名称中有“-”，因此“。” navigation is not working.导航不起作用。 Also since the child tags have same names, i cannot use it direct find.此外，由于子标签具有相同的名称，我不能使用它直接查找。 How can I navigate and iterate thru tags under '' ie '' tags?如何导航和遍历“即”标签下的标签？

You can probably do it like this:您可能可以这样做：
from lxml import etree
rules = """[your xml, fixed]"""
doc = etree.XML(rules)
for i in doc.xpath('//post-rulebase//entry'):
print(i.tag,i.attrib['name'])
for t in i.xpath('.//*'):
print(t.tag,t.text)
Output: Output：
entry some text
tag1 text
tag2 text
entry more text
tag1 text
tag2 text

Another method.另一种方法。
from simplified_scrapy import SimplifiedDoc, req, utils
html = '''
<address>
<entry name="text">
<tag1></tag1>>
<tag2></tag2>
</entry>>
</address>
<service>
....
</service>
<post-rulebase>
<entry name="some text">
<tag1>text</tag1>>
<tag2>text</tag2>
</entry>
<entry name="more text">
<tag1>text</tag1>>
<tag2>text</tag2>
</entry>
</post-rulebase>'''
doc = SimplifiedDoc(html)
entry = doc.select('post-rulebase').entry
print(entry)
print(entry.children.text)
Result:结果：
{'name': 'some text', 'tag': 'entry', 'html': '\n <tag1>text</tag1>>\n <tag2>text</tag2>\n '}
['text', 'text']
