我能够将SOAP消息中所需的详细信息转换为所需的Dictionary格式。但是，我在获取上面共享的此特定SOAP消息的详细信息时遇到了问题。在所有其他情况下，我只是得到了具有不同组合数量的单个酒店的响应，但在这个SOAP响应中我有两个酒店，我的解析代码同时从两个酒店获取房间的价格并对其进行排序。但是，我想在第一家酒店选择排序，然后在第二家酒店选择。酒店的数量可能会有所不同，因此尽量提供通用的解决方案，无论酒店数量多少都可以使用。
任何帮助都会受到重视。谢谢！

考虑使用XSLT简化XML，这是专门用于转换XML文档的声明性编程语言。 Python可以使用lxml模块运行XSLT 1.0。从那里将变换后的树解析为带有xmltodict的字典，可以进一步解析为json。所有三个输出都包含在下面：
XSLT 脚本（另存为.xsl文件，在.py脚本中引用）

Python 脚本（输出到xml，dict和json类型）
import lxml.etree as ET
import xmltodict
import json
# LOAD XML AND XSL
dom = ET.parse('soap.xml')
xslt = ET.parse('XSLTScript.xsl')
# TRANSFORM
transform = ET.XSLT(xslt)
newdom = transform(dom)
# NEW TREE OUTPUT
return_xml = ET.tostring(newdom, encoding='UTF-8', pretty_print=True, xml_declaration=True)
print(return_xml.decode("utf-8"))
return_dict = xmltodict.parse(return_xml)
print(return_dict)
return_json = json.dumps(return_dict, indent=4)
print(return_json)
转换的XML输出

答案 1 :(得分：0)
您正在从所有房价结果（尽管所有酒店）创建列表理解，但酒店代码不在任何类型的循环之内，与列表位于同一级别。 所以，你总会得到一家（最后一家）酒店。
在代码中：
'hc': _availability['@HotelCode'],
变量_可用性是前一循环的最后一次出现＆＃34;对于可用性的#availability＆＃34;。循环是正常的＆＃39;对于块，它甚至不会在那里定义。
在我看来，这种复杂的数据结构非常难以阅读和使用，也许您应该考虑OOP方法与对象属性中的数据。
如果你坚持使用这样的数据结构，你可以这样做：
def search_hotels_formatted_response(soap):
"""Parse the response."""
soap = xmltodict.parse(soap, process_namespaces=True)
# Deal with namespaces
env = 'http://schemas.xmlsoap.org/soap/envelope/:'

availability = listify(
soap[env + 'Envelope']
[env + 'Body']
[doorway + 'MultiAvailabilityResponse']
[doorway + 'Availabilities']
[doorway + 'Availability'])
# Intermediate data structure to hold room names
names = {
roomtype['@RoomTypeCode']: roomtype['@RoomTypeName']
for _availability in availability
for roomtype in listify(_availability
[doorway + 'RoomTypes']
[doorway + 'RoomType'])
}
# Intermediate data structure to hold rates

rate['@RoomTypeCode']: rate

for rate in listify(_availability
