如何漂亮地打印从 Python 中的请求库返回的 XML答案

【问题标题】：How to Pretty Print XML returned from Requests lib in python如何漂亮地打印从 Python 中的请求库返回的 XML

【问题描述】：

我正在使用“请求”库来运行 SOAP 服务。

headers = {'content-type': 'application/json'}
response = requests.post(test_url,data=testData.request_body,headers=headers)

响应如下（未格式化）

<?xml version="1.0" encoding="UTF-8"?>
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ns1="https://xxx.abc.in"><SOAP-ENV:Body><ns1:LoginResponse><return><SessionID>abc12345</SessionID><ResponseCode>0</ResponseCode><ResponseMessage>Successful</ResponseMessage></return></ns1:LoginResponse></SOAP-ENV:Body></SOAP-ENV:Envelope>

我如何漂亮地打印这个？

【解决方案1】：

您可以使用 beautifulsoup 传递 "xml" 作为解析器：

x = '''<?xml version="1.0" encoding="UTF-8"?>
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ns1="https://xxx.abc.in"><SOAP-ENV:Body><ns1:LoginResponse><return><SessionID>abc12345</SessionID><ResponseCode>0</ResponseCode><ResponseMessage>Successful</ResponseMessage></return></ns1:LoginResponse></SOAP-ENV:Body></SOAP-ENV:Envelope>'''

print(BeautifulSoup(x, "xml").prettify())

输出：

<?xml version="1.0" encoding="utf-8"?>
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ns1="https://xxx.abc.in">
 <SOAP-ENV:Body>
  <ns1:LoginResponse>
   <return>
    <SessionID>
     abc12345
    </SessionID>
    <ResponseCode>
     0
    </ResponseCode>
    <ResponseMessage>
     Successful
    </ResponseMessage>
   </return>
  </ns1:LoginResponse>
 </SOAP-ENV:Body>
</SOAP-ENV:Envelope>

【解决方案2】：

假设您从 xml 字符串开始：

#LXML
from lxml import etree
xmlRootNode = etree.fromstring(resp_str)
xmlstr = etree.tostring(xmlRootNode, xml_declaration=True, encoding="UTF-8", pretty_print=True)

或

#xml
import xml.etree.ElementTree as ET
import xml.dom.minidom
s = ET.tostring(xmlRootNode, encoding="UTF-8", method="xml")
xmln = xml.dom.minidom.parseString(resp_str)
xmlstr = xmln.toprettyxml()
