我有一个大的 HTML 文件，我需要使用正则表达式从中解析一些数据。首先是餐厅的名称。酒店名称采用以下格式：

共有40家酒店。我认为.在数字后面有两个空格。我需要列出所有的酒店1 to 40。我试过使用：

re.findall("[./0-9]", string_Name)

它输出数字。我想得到电话号码和所有酒店名称。我怎样才能做到这一点？

Blender 的答案给出了评级和餐厅名单。这很好，但我希望评级和餐厅名称使用不同的变量。

解析 HTML：

import re
from bs4 import BeautifulSoup

html = '''
<a href="https://courses.ischool.berkeley.edu/biz/capannina-san-francisco" id="bizTitleLink0">1.    Capannina
</a>
<a href="https://courses.ischool.berkeley.edu/biz/ristorante-parma-san-francisco" id="bizTitleLink4">5.     Ristorante Parma
</a>
'''

soup = BeautifulSoup(html)

for link in soup.find_all('a', text=re.compile(r'^\d')):
    print link.get_text()

和输出：

1.    Capannina

5.     Ristorante Parma

您不应该直接在 html 上运行正则表达式（最好先使用 HTML 解析器），但试试这个正则表达式：

(\d+)\.\s+([^<]+)

一位或多位数字

一个点

一个或多个空白字符

一个或多个非<字母

括号 () 的存在创建了一个捕获组。捕获组 1 的内容将是数字。捕获组 2 的内容将是名称。
