Spurious elements in HTML export

Spurious elements in HTML export

Hi,

Using the HTML exporter, I easily get spurious empty elements.
Example:

Org-mode:

* Section
[2014-05-15 jeu. 10:29]

** Subsection 1
[2014-05-15 jeu. 10:28]

Foo bar foo bar foo bar foo bar foo bar foo bar foo bar foo bar foo
bar foo bar foo bar foo bar foo bar foo bar foo bar foo bar foo bar
foo bar foo bar foo bar foo bar foo bar foo bar foo bar foo bar foo
bar foo bar foo bar foo bar foo bar foo bar foo bar foo bar

** Subsection 2
[2014-05-15 jeu. 10:29]

Foo bar foo bar foo bar foo bar foo bar foo bar foo bar foo bar foo
bar foo bar foo bar foo bar foo bar foo bar foo bar foo bar foo bar
foo bar foo bar foo bar foo bar foo bar foo bar foo bar foo bar foo
bar foo bar foo bar foo bar foo bar foo bar foo bar foo bar

After C-c C-e C-s C-b h H, HTML:

<div id="table-of-contents">
<h2>Table of Contents</h2>
<div id="text-table-of-contents">
<ul>
<li><a href="#sec-1">1. Subsection 1</a></li>
<li><a href="#sec-2">2. Subsection 2</a></li>
</ul>
</div>
</div>

<div class="figure">
<p>
</p>
</div>

<div id="outline-container-sec-1" class="outline-2">
<h2 id="sec-1"><span class="section-number-2">1</span> Subsection 1</h2>
<div class="outline-text-2" id="text-1">

<div class="figure">
<p>
</p>
</div>

<p>
Foo bar foo bar foo bar foo bar foo bar foo bar foo bar foo bar foo
bar foo bar foo bar foo bar foo bar foo bar foo bar foo bar foo bar
foo bar foo bar foo bar foo bar foo bar foo bar foo bar foo bar foo
bar foo bar foo bar foo bar foo bar foo bar foo bar foo bar
</p>
</div>
</div>

<div id="outline-container-sec-2" class="outline-2">
<h2 id="sec-2"><span class="section-number-2">2</span> Subsection 2</h2>
<div class="outline-text-2" id="text-2">

<div class="figure">
<p>
</p>
</div>

<p>
Foo bar foo bar foo bar foo bar foo bar foo bar foo bar foo bar foo
bar foo bar foo bar foo bar foo bar foo bar foo bar foo bar foo bar
foo bar foo bar foo bar foo bar foo bar foo bar foo bar foo bar foo
bar foo bar foo bar foo bar foo bar foo bar foo bar foo bar
</p>
</div>
</div>

My questions:
- is this what is expected ?
- why those 3 <p></p> ?
- why are they surrounded by those divs ?

I don't see the point in generating those empty <p></p> elements, and even
less in wrapping them with figure class.

If I remove the empty lines following the date/time stamps, then  I get
only the first of those empty blocks.
However, doing this, I trigger what i think is inconsistent between the
HTML and the LaTeX exporter: if there is no empty line after the date
stamp, the LaTeX exporter exports the date stamp. The HTML exporter doesn't.

Thanks for clarifications on this topic.

I can't reproduce this.  Do you have a recipe with a minimal
configuration ?

Also mention your Org and Emacs version.

Thanks,

This is already good to know!
I'll try to bisect my emacs config.

Recipe : the sole org fragment from my message in an org buffer,
and export the subtree in an html buffer with C-c C-e C-s C-b h H

I know ...).

I suspect the problem might come from org-html-standalone-image-p
(incorrectly finding an image for an empty paragraph) or even from
org-string-nw-p.

What org-string-nw-p should return on a string with the single EOL
character?

BTW, I wonder if org-html-standalone-image-p does actually what is
documented. It is documented
as returning non-nil in one of two cases: element is of type paragraph or
of type link.
But its code starts with:

 (and (eq (org-element-type paragraph) 'paragraph)
        ...)

which seems to prevent the second case. That is certainly unrelated to my
problem.

Sorry. I misread the code. Forget about this false interpretation.

Let's first try to safely reproduce the problem before pointing
fingers on some functions -- bisecting your config will surely
help!

This should be fixed. Thank you for reporting it.

Thanks for fixing it (and so quickly).

I have seen what went wrong in org-html-standalone-image-p
albeit I don't know what triggered it in my setup.
It has been an opportunity to remove a huge pile of old stuff from my Org
config :-)

Best regards,

Fabrice
