Python Regex-解析HTML [英] Python Regex - Parsing HTML

问题描述

我有这段代码，它给了我AttributeError:'NoneType'对象没有属性'group'.

I have this little code and it's giving me AttributeError: 'NoneType' object has no attribute 'group'.

import sys
import re

#def extract_names(filename):

f = open('name.html', 'r')
text = f.read()

match = re.search (r'<hgroup><h1>(\w+)</h1>', text)
second = re.search (r'<li class="hover">Employees: <b>(\d+,\d+)</b></li>', text)  

outf = open('details.txt', 'a')
outf.write(match)
outf.close()

我的意图是读取一个.HTML文件，以查找< h1> 标记值和员工人数，并将其附加到文件中.但是由于某种原因，我似乎无法正确处理.非常感谢您的帮助.

My intention is to read a .HTML file looking for the <h1> tag value and the number of employees and append them to a file. But for some reason I can't seem to get it right. Your help is greatly appreciated.
