实例如下所示：

									from xml.etree.cElementTree import ElementTree,Element

									import xlrd

									import re

									def read_xlsx(xlsx_path):

									  workbook = xlrd.open_workbook(xlsx_path)

									  booksheet = workbook.sheet_by_name("Sheet1")

									  p = list()

									  row_data = []

									  for row in range(booksheet.nrows):

									    for col in range(booksheet.ncols):

									      cel = booksheet.cell(row, col)

									      val = cel.value

									      try:

									        val = cel.value

									        val = re.sub(r'\s+', '', val)

									      except:

									        pass

									      if type(val) == float:

									        val = int(val)

									      else:

									        val = str(val)

									      row_data.append(val)

									  p.append(row_data)

									  return p

									def read_xml(Int_path):

									  tree = ElementTree()

									  tree.parse(Int_path)

									  return tree

									def write_xml(tree, out_path):

									  tree.write(out_path,encoding="utf-8",xml_declaration=True)

									  '''tree.write('output.xml')'''

									def if_match(node,k_name,k_val):

									  c = node.get(k_name)

									  if node.get(k_name) == k_val:

									    return True

									  return False

									def find_nodes(tree,path):

									  return tree.findall(path)

									def get_node_by_keyvalue(nodelist,key_name,key_val):

									  result_nodes=[]

									  for node in nodelist:

									    if if_match(node,key_name,key_val):

									      result_nodes.append(node)

									  return result_nodes

									def add_node_properties(nodelist,add_key,add_properties):

									  for node in nodelist:

									    node.set(add_key,add_properties)

									  return node

									if __name__ == "__main__":

									  tree = read_xml("./ContentList.xml")

									  nodes = find_nodes(tree,"Content")

									  P = read_xlsx("./ServiceId.xlsx")

									  a = P[0]

									  i = 0

									  while i < 80:

									    result_nodes = get_node_by_keyvalue(nodes , "AssetId" , a[i])

									    add_node_properties(result_nodes,"ServiceId",a[i+1])

									    i = i + 2

									  write_xml(tree,'./ContentList1.xml')
