Python Xml文件添加字节属性的方法
实例如下所示：
fromxml.etree.cElementTreeimportElementTree,Element
importxlrd
importre
defread_xlsx(xlsx_path):
workbook=xlrd.open_workbook(xlsx_path)
booksheet=workbook.sheet_by_name("Sheet1")
p=list()
row_data=[]
forrowinrange(booksheet.nrows):
forcolinrange(booksheet.ncols):
cel=booksheet.cell(row,col)
val=cel.value
try:
val=cel.value
val=re.sub(r'\s+','',val)
except:
pass
iftype(val)==float:
val=int(val)
else:
val=str(val)
row_data.append(val)
p.append(row_data)
returnp
defread_xml(Int_path):
tree=ElementTree()
tree.parse(Int_path)
returntree
defwrite_xml(tree,out_path):
tree.write(out_path,encoding="utf-8",xml_declaration=True)
'''tree.write('output.xml')'''
defif_match(node,k_name,k_val):
c=node.get(k_name)
ifnode.get(k_name)==k_val:
returnTrue
returnFalse
deffind_nodes(tree,path):
returntree.findall(path)
defget_node_by_keyvalue(nodelist,key_name,key_val):
result_nodes=[]
fornodeinnodelist:
ifif_match(node,key_name,key_val):
result_nodes.append(node)
returnresult_nodes
defadd_node_properties(nodelist,add_key,add_properties):
fornodeinnodelist:
node.set(add_key,add_properties)
returnnode
if__name__=="__main__":
tree=read_xml("./ContentList.xml")
nodes=find_nodes(tree,"Content")
P=read_xlsx("./ServiceId.xlsx")
a=P[0]
i=0
whilei<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')
