feat: convert native HTML line breaks <br> to Markdown line breaks

[spudart]

Thank you so much for making such a great tool to export notes from Evernote to Markdown for Obsidian.

I've noticed that Yarle is not converting <br> tags in my CDATA.

Here is an enex file with one test note:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE en-export SYSTEM "http://xml.evernote.com/pub/evernote-export3.dtd">
<en-export export-date="20240108T214207Z" application="Evernote" version="Evernote Mac 7.14 (458265)">
<note><title>Note with line breaks</title><content><![CDATA[<!DOCTYPE en-note SYSTEM "http://xml.evernote.com/pub/enml2.dtd"><en-note>
Line 1<br></br>
Line 2<br>
Line 3<br/>
Line 4<br />
Line 5<br clear="none"/>
Line 6<p></p>
<p>Line 7</p>
<div>Line 8<br></br></div>
<div>Line 9<br></div>
<div>Line 10<br/></div>
<div>Line 11<br /></div>
<div>Line 12<br clear="none"/></div>
<div>Line 13<p></p></div>
<div><p>Line 14</p></div>
<div>Line 15</div>
<div>Line 16</div>
</en-note>]]></content><created>20240108T214113Z</created><updated>20240108T214144Z</updated><tag>test2</tag><tag>test1</tag><note-attributes><latitude>41.87312697527578</latitude><longitude>-88.07482909555657</longitude><altitude>0</altitude><author>Matt Maldre</author><source>desktop.mac</source><reminder-order>0</reminder-order></note-attributes></note>
</en-export>

Yarle is outputting this:

Line 1Line 2Line 3Line 4Line 5Line 6

Line 7

Line 8
Line 9
Line 10
Line 11
Line 12
Line 13

Line 14

Line 15
Line 16

Whereas it would be fantastic if Yarle generated this instead:

Line 1
Line 2
Line 3
Line 4
Line 5
Line 6

Line 7

Line 8
Line 9
Line 10
Line 11
Line 12
Line 13

Line 14

Line 15
Line 16

Am I missing something that the <br> tags in my notes are not being converted to line breaks?

Hi @spudart ,

Thanks for the details and the enex file! I think it is because Evernote stores newline-ish looklike differently, not as plain
tag.

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE en-export SYSTEM "http://xml.evernote.com/pub/evernote-export4.dtd">
<en-export export-date="20240108T223036Z" application="Evernote" version="10.68.3">
  <note>
    <title>newlines</title>
    <created>20240108T223014Z</created>
    <updated>20240108T223024Z</updated>
    <note-attributes>
    </note-attributes>
    <content>
      <![CDATA[<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<!DOCTYPE en-note SYSTEM "http://xml.evernote.com/pub/enml2.dtd"><en-note><div>line1</div><div>line2</div><div><br/></div></en-note>      ]]>
    </content>
  </note>
</en-export>

So in this case the div tags separate the content like newlines in html, hence
is being removed, as it encapsulated by an other div.
But anyway, if you think it's meaningful, I'm happy to introduce a new config option named "Convert newline HTML tags" to produce the desired behavior.

@akosbalasko The config option "Convert newline HTML tags" would be incredible! Thank you!

hi @spudart ,
technically in the provided enex is converted like as follows becase there is
in each line between line 8 and line 12, then newlines are going to be converted because

from the upcoming lines.
So, this is what we have now, if "convert Plain html newlines" is ticked:

Line 1
Line 2
Line 3
Line 4
Line 5
Line 6

Line 7

Line 8

Line 9

Line 10

Line 11

Line 12

Line 13

Line 14

Line 15
Line 16
