I'm trying to write a small function for another script that pulls the generated text from "" Essentially, I need it to pull whatever sentence is between < br> tags.

I've been trying my darndest using regular expressions, but I never really could get the hang of those. All of the searching I did turned up things for pulling either specific sentences, or single words. This however needs to pull whatever arbitrary string is between < br> tags.

Can anyone help me out? Thanks.

Best I could come up with:

html = urlopen("").read()
output = re.findall('\<br>.*\<br>', html)

EDIT: Ended up going with a different approach all together, simply splitting the HTML in a list seperated by < br> and pulling [3], made for cleaner code and less string operations. Keeping this question up for future reference and other people with similar questions.

You need to use the DOTALL flag as there are newlines in the expression that you need to match. I would use

re.findall('<br>(.*?)<br>', html, re.S)

However will return multiple results as there are a bunch of <br><br> on that page. You may want to use the more specific:

re.findall('<hr><br>(.*?)<br><hr>', html, re.S)

How do I scrape a randomly generated sentence from this website , You will find more details here Using python Requests with js pages When I run your code I get a blob of html output. <p>If you're visiting this page, you're likely here because you're searching for a random sentence. In this tutorial, you will learn about regular expressions (RegEx), and use Python's re module to work with RegEx (with the help of examples). A Re gular Ex pression (RegEx) is a sequence of characters that defines a search pattern.

from urllib import urlopen
import re
html = urlopen("").read()
output = re.findall('<body>.*?>\n*([^<]{5,})<.*?</body>', html, re.S)

if (len(output) > 0):
    output = re.sub('\n', ' ', output[0])
    output = re.sub('\t', '', output)

A black cat crossing your path signifies that the animal is going somewhere. -- Groucho Marx

You could also strip of the final \n's and replace all those inside the text (on longer quotes) with <br /> if you are displaying it in HTML again, so you would maintain the original line breaks visually.

7.2. re — Regular expression operations — Python v3.1.5 , This module provides regular expression matching operations similar to those Regular expressions use the backslash character ('\') to indicate special forms or the characters in each word of a sentence except for the first and last characters: >>> def repl(m): inner_word = list( random.shuffle( inner_word)� RegEx Module. Python has a built-in package called re, which can be used to work with Regular Expressions.. Import the re module:

All jokes of that page have the same model, no ambigous things, you can use this

output = re.findall('(?<=<br>\s)[^<]+(?=\s{2}<br)', html)

No need to use the dotall flag cause there's no dot.
