为什么我没有得到正确的回答？

Question

I am a complete Python noob 既然铺垫已经完成，我正试图从SOAP响应中解析一些信息。 回复正文如下：

   <soap:Body>
  <ProcessMessageResponse xmlns="http://www.starstandards.org/webservices/2005/10/transport">
     <payload>
        <content id="Content0">
           <CustomerLookupResponse xmlns="">
              <Customer>
                 <CompanyNumber>ZQ1</CompanyNumber>
                 <CustomerNumber>1051012</CustomerNumber>
                 <TypeCode>I</TypeCode>
                 <LastName>NAME</LastName>
                 <FirstName>BASIC</FirstName>
                 <MiddleName/>
                 <Salutation/>
                 <Gender/>
                 <Language/>
                 <Address1/>
                 <Address2/>
                 <Address3/>
                 <City/>
                 <County/>
                 <StateCode/>
                 <ZipCode>0</ZipCode>
                 <PhoneNumber>0</PhoneNumber>
                 <BusinessPhone>0</BusinessPhone>
                 <BusinessExt>0</BusinessExt>
                 <FaxNumber>0</FaxNumber>
                 <BirthDate>0</BirthDate>

                 <AssignedSalesperson/>
                 <CustomerType/>
                 <PreferredPhone/>
                 <CellPhone>0</CellPhone>
                 <PagePhone>0</PagePhone>
                 <OtherPhone>0</OtherPhone>
                 <OtherPhoneDesc/>
                 <Email1/>
                 <Email2/>
                 <OptionalField/>
                 <AllowContactByPostal/>
                 <AllowContactByPhone/>
                 <AllowContactByEmail/>
                 <BusinessPhoneExtension/>
                 <InternationalBusinessPhone/>
                 <InternationalCellPhone/>
                 <ExternalCrossReferenceKey>0</ExternalCrossReferenceKey>
                 <InternationalFaxNumber/>
                 <InternationalOtherPhone/>
                 <InternationalHomePhone/>
                 <CustomerPreferredName/>
                 <InternationalPagerPhone/>
                 <PreferredLanguage/>
                 <LastChangeDate>20130401</LastChangeDate>
                 <Vehicles/>
                 <CCID/>
                 <CCCD>0</CCCD>
              </Customer>
           </CustomerLookupResponse>
        </content>
     </payload>
  </ProcessMessageResponse>
</soap:Body>

我有下面的代码片段来展示我如何解析出我想要的响应：

^{pr2}$

我不确定我为什么得到' ', ' ', ' ', <xml response>...的输出

Answer 1

看起来您过度指定了字段名，因此它们不匹配任何内容，因此您的for customer in ...永远不会运行。试试这个：

import httplib
import xml.etree.ElementTree as ET

def send_customer_lookup(data):
    soap_action = 'http://www.starstandards.org/webservices/2005/10/transport/operations/ProcessMessage'
    source_port = random.randint(6000, 20000)
    with httplib.HTTPSConnection('otqa.arkona.com', source_address=('', source_port)) as webservice:
        webservice.putrequest('POST', '/OpenTrack/Webservice.asmx?wsdl')
        webservice.putheader('User-Agent', 'OpenTrack-Heartbeat')
        webservice.putheader('Content-Type', 'application/soap+xml')
        webservice.putheader('Content-Length', '%d' % len(data))
        webservice.putheader('SOAPAction', soap_action)
        webservice.endheaders()
        webservice.send(data)
        response_xml = str(webservice.getresponse().read())

    doc = ET.fromstring(response_xml)
    results = []
    for customer in doc.findall('.//CustomerLookupResponse/'):
        customer_number     = customer.findtext('CustomerNumber')
        customer_first_name = customer.findtext('FirstName')
        customer_last_name  = customer.findtext('LastName')
        results.append((customer_number, customer_first_name, customer_last_name))

   return results

另外，全局变量名通常是邪恶的；我想您之所以添加它们是因为遇到了“variable not defined”错误？这应该是for循环实际上没有运行的线索。在

Answer 2

你可以利用xml.dom.minidom公司名称：

from xml.dom import minidom

def parse_customer_data(response_xml):
    results = []
    dom = minidom.parseString(response_xml)
    customers=dom.getElementsByTagName('Customer')
    for c in customers:                                                                                                                      
        results.append({
            "cnum"  : c.getElementsByTagName('CustomerNumber')[0].firstChild.data,
            "lname" : c.getElementsByTagName('LastName')[0].firstChild.data,
            "fname" : c.getElementsByTagName('FirstName')[0].firstChild.data
       })
    return results

if __name__ == "__main__":
    response_xml = open("soap.xml").read()
    results = parse_customer_data(response_xml)
    print(results)

注意，对于输入文件，肥皂.xml: 1我添加了xml版本/soap:信封元素围绕您提供的XML，否则它将无法解析 2我添加了另一个Customer元素来测试我的代码

输出：

^{pr2}$
