Web scraping with Beautiful Soup gives empty ResultSet

I am experimenting with Beautiful Soup and I am trying to extract information from a HTML document that contains segments of the following type:

<div class="entity-body">
<h3 class="entity-name with-profile">
<a href="https://www.linkedin.com/profile/view?id=AA4AAAAC9qXUBMuA3-txf-cKOPsYZZ0TbWJkhgfxfpY&amp;trk=manage_invitations_profile" 
data-li-url="/profile/mini-profile-with-connections?_ed=0_3fIDL9gCh6b5R-c9s4-e_B&amp;trk=manage_invitations_miniprofile" 
class="miniprofile" 
aria-label="View profile for Ivan Grigorov">
<span>Ivan Grigorov</span>
</a>
</h3>
<p class="entity-subheader">
Teacher
</p>
</div>

I have used the following commands:

with open("C:\Users\pv\MyFiles\HTML\Invites.html","r") as Invites: soup = bs(Invites, 'lxml')
soup.title
out: <title>Sent Invites\n| LinkedIn\n</title>
invites = soup.find_all("div", class_ = "entity-body")
type(invites)
out: bs4.element.ResultSet
len(invites)
out: 0

Why find_all returns empty ResultSet object?

Your advice will be appreciated.

Solution

The problem is that the document is not read, it is a just TextIOWrapper (Python 3) or File(Python 2) object. You have to read the documet and pass markup, essentily a string to BeautifulSoup.

The correct code would be:

with open("C:\Users\pv\MyFiles\HTML\Invites.html", "r") as Invites:
    soup = BeautifulSoup(Invites.read(), "html.parser")
    soup.title
    invites = soup.find_all("div", class_="entity-body")
    len(invites)
