Why does the regular expression with the tag not work?

Question

Python

I'm trying to rip out the text using reg. expression, under the tag that is inside a particular table:<nobr>

soup = BeautifulSoup(resArrow, 'lxml')
tbl = soup.find('tbl', id='maintbl')

for nobr in tbl.find_all('nobr', text=re.compile("MB")):
  # ничего не находится

An example of outputting the content of one of the required tags :<nobr>

<nobr>1895.35 MB<br/><a href="down.php?id=555"><b>2,55 tlm</b></a></nobr>

print (nobr.getText())issues

1895.35 MB2.55 tlm

In general, the key " MB " is, but for some reason it is not picked up in my regular expression. I already tried like this:

for nobr in tbl.find_all('nobr', text=re.compile(".*MB.*")):

Yes, and just indicated the exact line

for nobr in tbl.find_all('nobr', text="1895.35 MB2,55 tlm"):

for nobr in tbl.find_all('nobr', text="1895.35 MB"):

, but also found nothing.

What could be the problem?

Thank you!

PS I understand that instead of a regular expression, you can accept all tags in a row and then perform a comparison:<nobr>

for nobr in tbl.find_all('nobr'):
    if "MB" in nobr.getText(): # так работает

, but I really want to figure out what's wrong with the regular season.
