Python Xml文件添加字节属性的方法

实例如下所示：fromxml.etree.cElementTreeimportElementTree,Elementimportxlrdimportredefread_xlsx(xlsx_path):workbo

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')
