【问题描述】：
我正在尝试使用 ElementTree 遍历树中的所有节点和子节点。我想将所有父及其子 XML 标记作为列和值，以 CSV 格式将子节点附加到父节点。我正在使用python 2.7。标题应该只打印一次&下面应该是各自的值
XML 文件：

我的代码：
#Import Libraries
import csv
import xmlschema
import xml.etree.ElementTree as ET
#Define the variable to store the XML Document
xml_file = 'C:/Users/391648/Desktop/BOSS_20190618_20190516_18062019141928_CUMA/source_Files_XML/CustomersOrders.xml'
#using XML Schema Library validate the XML against XSD
my_schema = xmlschema.XMLSchema('C:/Users/391648/Desktop/BOSS_20190618_20190516_18062019141928_CUMA/source_Files_XML/CustomersOrders.xsd')
SchemaCheck = my_schema.is_valid(xml_file)
print(SchemaCheck) #Prints as True if the document is validated with XSD
#Parse XML & get root
tree = ET.parse(xml_file)
root = tree.getroot()
#Create & Open CSV file
xml_data_to_csv = open('C:/Users/391648/Desktop/BOSS_20190618_20190516_18062019141928_CUMA/source_Files_XML/PythonXMl.csv','w')
#create variable to write to csv
csvWriter = csv.writer(xml_data_to_csv)
#Create list contains header
count =0
#Loop for each node
for element in root.findall('Customers/Customer'):
List_nodes = []
#Get head by Tag
if count ==0:
list_header =[]
Full_Address = []
CompanyName = element.find('CompanyName').tag
list_header.append(CompanyName)
ContactName = element.find('ContactName').tag
list_header.append(ContactName)
ContactTitle = element.find('ContactTitle').tag
list_header.append(ContactTitle)
Phone = element.find('Phone').tag
list_header.append(Phone)
print(list_header)
csvWriter.writerow(list_header)
count = count + 1
#Get the data of the Node
CompanyName = element.find('CompanyName').text
List_nodes.append(CompanyName)
ContactName = element.find('ContactName').text
List_nodes.append(ContactName)
ContactTitle = element.find('ContactTitle').text
List_nodes.append(ContactTitle)
Phone = element.find('Phone').text
List_nodes.append(Phone)
print(List_nodes)
#Write List_Nodes to CSV
csvWriter.writerow(List_nodes)
xml_data_to_csv.close()
Expected CSV output:
CompanyName,ContactName,ContactTitle,Phone, Address, City, Region, PostalCode, Country
Great Lakes Food Market,Howard Snyder,Marketing Manager,(503) 555-7555, City Center Plaza 516 Main St., Elgin, OR, 97827, USA
Hungry Coyote Import Store,Yoshi Latimer,Sales Representative,(503) 555-6874, 12 Orchestra Terrace, Walla Walla, WA, 99362, USA

不应该是
root.findall('Customer')吗？
