Question

我正在编写一个脚本来进行一些探索性分析。该脚本引用了ID的API，API响应XML输出（没有子对象）

脚本：

import requests
import xml.etree.ElementTree as et


xml ='''    
<?xml version="1.0" encoding="UTF-8"?>
<YM>
   <Version>xxx</Version>
   <ApiKey>xxx</ApiKey>
   <CallID>xxx</CallID>
   <></>
   <SaPasscode>xxxx</SaPasscode>
   <Call Method = "GetIDs">

   </Call>
</YM>
'''        
headers = {'Content-Type': 'application/x-www-form-urlencoded'}
r = requests.post('url', data=xml, headers=headers)

示例输出：

<Members>
<Sa.Members.All.GetIDs>
<YourMembership_Response>
<ID>1234</ID>
<ID>4321</ID>
</Members>
</Sa.Members.All.GetIDs>
</YourMembership_Response>

我使用这些ID并将它们插入到另一个API调用中，以通过迭代函数将同一脚本中的ID获取更多信息，该函数将上述API调用中的ID解析为另一个获取每个API调用的API调用ID：

脚本：

def xml_event_info(eventID):       
    xml ='''        
    <?xml version="1.0" encoding="UTF-8"?>
    <YourMembership>
       <Version>xxx</Version>
       <ApiKey>xxx</ApiKey>
       <CallID>xxx</CallID>
       <></>
       <SaPasscode>xxx</SaPasscode>
       <Call Method = "Profile.Get">
           <ID>{}</ID>
       </Call>
    </YourMembership>        
    '''        
    headers = {'Content-Type': 'application/x-www-form-urlencoded'}
    r = requests.post('url', 
                      data=xml.format(eventID), headers=headers)        
    print(r.text)      




# BUILD XML TREE OBJECT    
dom = et.fromstring(r.text)

# PARSE EVENT ID TEXT AND PASS INTO FUNCTION
for i in dom.iterfind('.//ID'):
     xml_event_info(i.text)

示例输出（然后显示更多XML对象）：

<?xml version="1.0" encoding="utf-8" ?>

<Response>
<ErrCode>xxx</ErrCode>
<ExtendedErrorInfo>xxx</ExtendedErrorInfo>
<Profile.Get>
<ID>xxxx</ID>
<WebsiteID>xxxx</WebsiteID>
<EmailBounced>xxx</EmailBounced>
<NamePrefix>xxx</NamePrefix>
<FirstName>xxx</FirstName>
</Profile.Get>
</Response>

我想从第二个API调用中获取上述示例及其许多XML属性，并将它们映射到pandas数据帧。我遇到的问题是，当我尝试在此处找到的for循环内部使用函数(xml_event_info(i.text))时，它保存第二个API调用输出：

# PARSE EVENT ID TEXT AND PASS INTO FUNCTION
for i in dom.iterfind('.//ID'):
     xml_event_info(i.text)

我正在尝试映射xml以映射到数据框中并且我不断收到错误＆＃39; TypeError：Parse（）参数1必须是字符串或只读缓冲区，而不是无＆＃39; < /强>

如何将多个API调用的XML输出解析为pandas数据帧，其中每个XML标记都是数据帧的标题

Example: ---|ErrCode|ExtendedInfo|ID|FirstName----

我所指的完成工作的脚本和网站可在此处找到（http://www.austintaylor.io/lxml/python/pandas/xml/dataframe/2016/07/08/convert-xml-to-pandas-dataframe/）

脚本：

def xml2df(): tree = et.fromstring(xml_event_info(i.text)) root = tree.getroot() all_records = [] headers = [] for i, child in enumerate(root): record = [] for subchild in child: record.append(subchild.text) if subchild.tag not in headers: headers.append(subchild.tag) all_records.append(record) return pd.DataFrame(all_records, columns=headers)

完整的脚本：

import requests import xml.etree.ElementTree as et import pandas as pd from lxml import etree xml =''' <?xml version="1.0" encoding="UTF-8"?> <YourMembership> <Version>xxx</Version> <ApiKey>xxxx</ApiKey> <CallID>xxx</CallID> <></> <SaPasscode>xxx</SaPasscode> <Call Method = "Events.All.GetIDs"> <StartDate>2017/01/1</StartDate> <EndDate>2017/01/31</EndDate> </Call> </YourMembership> ''' headers = {'Content-Type': 'application/x-www-form-urlencoded'} r = requests.post('url', data=xml, headers=headers) def xml_event_info(eventID): xml =''' <?xml version="1.0" encoding="UTF-8"?> <YourMembership> <Version>xxx</Version> <ApiKey>xxx</ApiKey> <CallID>xxx</CallID> <></> <SaPasscode>xxx</SaPasscode> <Call Method = "Event.Get"> <EventID>{}</EventID> </Call> </YourMembership> ''' headers = {'Content-Type': 'application/x-www-form-urlencoded'} r = requests.post('url', data=xml.format(eventID), headers=headers) print(r.text) return r.text # BUILD XML TREE OBJECT dom = et.fromstring(r.text) # PARSE EVENT ID TEXT AND PASS INTO FUNCTION for i in dom.iterfind('.//EventID'): y = xml_event_info(i.text) for xml in y: tree = et.fromstring(y) root = tree.getchildren() all_records = [] headers = [] for i , child in enumerate(root): record = [] for subchild in child: record.append(subchild.text) if subchild.tag not in headers: headers.append(subchild.tag) all_records.append(record) #print all_records print pd.DataFrame(all_records, columns=headers)

编辑：

TLDR：

如何使下面函数的输出映射到数据框中，xml元素作为数据框的标题：

import requests import xml.etree.ElementTree as et import pandas as pd xml =''' <?xml version="1.0" encoding="UTF-8"?> <YourMembership> <Version>xxx</Version> <ApiKey>xxxx</ApiKey> <CallID>xxx</CallID> <></> <SaPasscode>xxxx</SaPasscode> <Call Method = "GetIDs"> </Call> </YourMembership> ''' headers = {'Content-Type': 'application/x-www-form-urlencoded'} r = requests.post('url', data=xml, headers=headers) def xml_event_info(eventID): xml =''' <?xml version="1.0" encoding="UTF-8"?> <YourMembership> <Version>xxx</Version> <ApiKey>xxx</ApiKey> <CallID>xxx</CallID> <></> <SaPasscode>xxx</SaPasscode> <Call Method = "Profile.Get"> <ID>{}</ID> </Call> </YourMembership> ''' headers = {'Content-Type': 'application/x-www-form-urlencoded'} r = requests.post('url', data=xml.format(eventID), headers=headers) print(r.text)

输出：

<?xml version="1.0" encoding="utf-8" ?> <Response> <ErrCode>xxx</ErrCode> <ExtendedErrorInfo>xxx</ExtendedErrorInfo> <Profile.Get> <ID>xxxx</ID> <WebsiteID>xxxx</WebsiteID> <EmailBounced>xxx</EmailBounced> <NamePrefix>xxx</NamePrefix> <FirstName>xxx</FirstName> </Profile.Get> </Response>

Answer 1

HwndSource函数没有返回任何内容，只需在结尾处添加xml_event_info(eventID)语句，然后重试。

return

如何在＆＃39;内部输出功能？循环并使用它构建数据帧？
