python处理xml并打包成exe带参数运行

1.python处理xml代码如下

import datetime
import xml.dom.minidom
import random
import re
import sys

filename=sys.argv[1] #打包成exe并接收参数
#filename='samplexml.txt'  #本地调试用
filepath=''+filename

with open(filepath,'r',encoding='utf-8') as f:#文档预处理为utf-8格式
	content=f.read()
	newcontent=[line for line in content.splitlines() if line.strip()] #去掉空行
	datasource='\n'.join(newcontent)
	f.close()

tree=xml.dom.minidom.parseString(datasource) #minidom模块只支持utf-8格式文档

num=str(random.randint(10000000,99999999))

#获取某个标签
ele01=tree.getElementsByTagName('id')[0]
newid='202402213000'+num
ele01.firstChild.data=newid

ele02=tree.getElementsByTagName('author')[2]
ele02.firstChild.data='Bella'


now=datetime.datetime.now()
time=str(datetime.datetime.timestamp(now))
timestr=time.replace('.','')
resultname=filename.replace('.txt','_')+timestr+'.txt'

with open(resultname,'w',encoding='GBK') as f:
	tree.writexml(f,addindent='',newl='\n',encoding='GBK')

2.安装pyinstaller

3.打包成带一个参数的exe，打包好的文件在dist文件夹下

4.执行exe

因为传的参数就是一个文件，事先把文件放到exe文件同级的目录下。

用以下命令进行执行。没报错，且生成了新文件就算执行成功了

注意：要处理的xml文件不能带注释。

smaplexml.txt内容如下：

<?xml version="1.0" encoding="GBK"?>
