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_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')
以上这篇Python Xml文件添加字节属性的方法就是小编分享给大家的全部内容了，希望能给大家一个参考，也希望大家多多支持编程小技巧。
