今天学习python的时候发现一个好玩儿的工具叫做tidy。 安装很简单 yaourt -S tidyhtml 可以直接在命令行中使用
tidy file
python code $ cat chapters-15-tidy.py
#!/usr/bin/python2
from subprocess import Popen, PIPE
text = open(‘./messy.html’).read()
tidy = Popen(‘tidy’, stdin=PIPE, stdout=PIPE, stderr=PIPE)
tidy.stdin.write(text)
tidy.stdin.close()
print tidy.stdout.read()
然后就自动输出修复后的文件。同样搭配 **>**可以重定向到文件。同时这个命令在默认情况下还可以输出修复了那些内容。 例如原文：
$ cat messy.html
