Using BeautifulSoup to find a HTML tag that contains certain text

Question

I\'m trying to get the elements in an HTML doc that contain the following pattern of text: #\\S{11}

 this is cool #12345678901 
<         


        

Answer 1

from BeautifulSoup import BeautifulSoup
import re

html_text = """
this is cool #12345678901
this is nothing
foo #126666678901
this is interesting #126666678901
this is blah #124445678901
"""

soup = BeautifulSoup(html_text)


for elem in soup(text=re.compile(r' #\S{11}')):
    print elem.parent

Prints:

this is cool #12345678901
this is interesting #126666678901
this is blah #124445678901
