Search In HTML Page Using Regex Patterns With Python

February 09, 2023 Post a Comment

I'm trying to find a string inside a HTML page with known patterns. for example, in the following HTML code:

Solution 1:

re.findall(r'<HR>\s*<font size="\+1">(.*?)</font><BR>', html, re.DOTALL)

findall is returning a list with everything that is captured between the brackets in the regular expression. I used re.DOTALL so the dot also captures end of lines.

I used \s* because I was not sure whether there would be any whitespace.

Solution 2:

This works, but may not be very robust:

import re
r = re.compile('<HR>\s?<font size="\+1">(.+?)</font>\s?<BR>', re.IGNORECASE)
r.findall(html)

You will be better off using a proper HTML parser. BeautifulSoup is excellent and easy to use. Look it up.

Solution 3:

re.findall(r'<HR>\n<font size="\+1">([^<]*)<\/font><BR>', html, re.MULTILINE)
