Strange "tag mismatch"

[Sam Sahara]

Calibre 3.6

The <br class="brs" /> tag is evaluated as an error with the following message:

ERROR: Parsing failed: Opening and ending tag mismatch: br line 11 and h2, line 11, column 87****[OEBPS/text/content0078.xhtml]

If I close the tag this way: <br class="brs"></br> the above error is no more raised. It seems to be a wrong behaviour, as I can read on w3schools.com:

In HTML, the <br> tag has no end tag.

In XHTML, the <br> tag must be properly closed, like this: <br />.

<br class="brs" /> is not an error and the editor does not mark it as an error, at least for me.

Here you are a screen-shot of the editor with <br class="brs"/>

And here's a screenshot showing that it works for me with calibre 3.7 on my linux system.

Maybe is a problem with a python module. How can I test this hypothesis?

I have:
Python 2.7.12 (default, Nov 19 2016, 06:48:10) [GCC 5.4.0 20160609] on linux2
Python 3.5.2 (default, Nov 17 2016, 17:05:23) [GCC 5.4.0 20160609] on linux

take a close look at your highlighted code again
br is a self closing tag like you show in your initial post
But your error has

br/>

on the second line

I adjust the <p or <h line height when I want BR to make a bigger gap

[kovidgoyal]

Install the binary calibre from https://calibre-ebook.com/download_linux it uses its own bundled python.

Works on my Linux Mint 18.2 Cinnamon 64bit Kernel 4.8.0-53-generic calibre 3.7.

Does the <br /> need a different doctype for correct handling?

[kovidgoyal]

The doctypes in my screenshot and the OPs screenshot are the same.

[Sam Sahara]

Just to add a little bit of confusion.

the following line raise the above error:

<h2 id="heading_id_233" class="center">ANIMA CARA<br class="brs">(gennaio 1899)</h2>

the same line, but with two more break lines, does not raise any error:

<h2 id="heading_id_233" class="center">ANIMA CARA
<br class="brs">
(gennaio 1899)</h2>

That error is because you failed to close the BR tag (red)

[kovidgoyal]

Both of those raise an error for me. But note that with parsing errors often only the first error is reported, so if you have both of those in the same file, only the first one will be reported. Once you fix the first, the second will be reported. This is because the parser aborts on encountering an error it cannot handle.
