How does Nokogiri handle closed HTML tags, for example?

When parsing an HTML document, how does Nokogiri handle tags <br>? Suppose we have a document similar to this:

<div>
   Hi <br>
   How are you? <br>
</div>

Do you know Nokogiri that tags <br>are something special, not just regular XML tags and ignore them when parsing a node feed? I think Nokogiri is smart, but I want to make sure before I accept this project, which includes a cleanup site written in HTML4. You know what I mean ( How are you?not the content of the first <br>, as it would be in XML).

As far as I remember, starting with some HTML analysis last year, he will consider them as separate.

EDIT: My bad one, I just got someone to send me the code and tested it, we ended up with something like <br>separately.
