Markdown Discuss - Sep 2007 - [Possible Bug]: Additional <p> wrapper around HTML input

I hope this is not by design and not an already discussed bug.

Take the following input:

    <hr id="foo" />
    
    <hr id="foo">

    <hr id="foo"/>

    <hr id="foo" />
    <hr id="foo">
    <hr id="foo"/>

If this is run through Markdown a paragraph will wrap hr's numer 4-6. This 
behaviour can be found in both Markdown.pl and Markdown.php (I used the 
Dingus provided on the project pages).

Interesting is, that Markdown Extra handles this correctly.

PS: The above input is a snippet from `MDTest/markdown.mdtest/Inline HTML 
(Simple).text`

Well, it's a documented limitation on the Markdown syntax page: "The  
only restrictions are that block-level HTML elements -- e.g. `<div>`,  
`<table>`, `<pre>`, `<p>`, etc. -- must be separated from
surrounding
content by blank lines, and the start and end tags of the block  
should not be indented with tabs or spaces."

"hr" is a block-level element, but you have not separated them by a  
blank line.

This is a "designed" limitation to simplify the parser. It doesn't
mean a parser shouldn't do better, and I believe John is trying to  
improve Markdown.pl to remove some limitations like this one.

Indeed, Markdown Extra's HTML block parser is much better at that  
than PHP Markdown's or the one in Markdown.pl.
