I\'m trying to get the elements in an HTML doc that contain the following pattern of text: #\\S{11}
this is cool #12345678901
<
With bs4 (Beautiful Soup 4), the OP's attempt works exactly like expected:
from bs4 import BeautifulSoup
soup = BeautifulSoup("<h2> this is cool #12345678901 </h2>")
soup('h2',text=re.compile(r' #\S{11}'))
returns [<h2> this is cool #12345678901 </h2>]
.
from BeautifulSoup import BeautifulSoup
import re
html_text = """
<h2>this is cool #12345678901</h2>
<h2>this is nothing</h2>
<h1>foo #126666678901</h1>
<h2>this is interesting #126666678901</h2>
<h2>this is blah #124445678901</h2>
"""
soup = BeautifulSoup(html_text)
for elem in soup(text=re.compile(r' #\S{11}')):
print elem.parent
Prints:
<h2>this is cool #12345678901</h2>
<h2>this is interesting #126666678901</h2>
<h2>this is blah #124445678901</h2>
BeautifulSoup search operations deliver [a list of] BeautifulSoup.NavigableString
objects when text=
is used as a criteria as opposed to BeautifulSoup.Tag
in other cases. Check the object's __dict__
to see the attributes made available to you. Of these attributes, parent
is favored over previous
because of changes in BS4.
