实例如下所示：

from xml.etree.cElementTree import ElementTree,Elementimport xlrdimport redef 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 pdef read_xml(Int_path):  tree = ElementTree()  tree.parse(Int_path)  return treedef 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 Falsedef 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_nodesdef add_node_properties(nodelist,add_key,add_properties):  for node in nodelist:    node.set(add_key,add_properties)  return nodeif __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')
