如何使用BeautifulSoup解析包含名称空间的XSD

给定一个XML Schema我想创建一个包含所有XML元素名称的数组。我的错误是我的结果是空的

In [31]: import requests
    ...: from bs4 import BeautifulSoup
    ...: 
    ...: result = requests.get('http://www.ddialliance.org/Version2-1.xsd')
    ...: content = result.content
    ...: 
    ...: soup = BeautifulSoup(content, 'lxml')
    ...: 

In [32]: print(soup.html.body.next_element.name)
xs:schema

In [34]: schema = soup.html.body.next_element

In [35]: all_xml_element_tags = schema.find_all("xs:element", {"minOccurs" : "0"})
    ...: 

In [36]: all_xml_element_tags
Out[36]: []

所以我希望拥有Schema的所有元素名称

结果集应该有值...... 

In [39]: soup.find_all("xs:element", {"minOccurs" : "0"})
Out[39]: []

那么如何查询呢。

答案 0 :(得分：2)

请注意，将解析模式从lxml更改为xml至关重要。

代码：

import requests
from bs4 import BeautifulSoup

result = requests.get('http://www.ddialliance.org/Version2-1.xsd')
content = result.text

soup = BeautifulSoup(content, 'xml')
all_xml_element_tags = soup.find_all("xs:element", minOccurs="0") # You can also use this too: all_xml_element_tags = soup.find_all("xs:element", {"minOccurs":"0"})


print(all_xml_element_tags)

输出：
