Please describe the problem:
The HTML parser seems to add whitespace around block-level elements.  For instance:

<ul><li>item1</li><li>item2</li></ul>

When using xmllint -html you get:

<ul>
<li>item1</li>
<li>item2</li>
</ul>

This appears safe, but with some CSS rules this whitespace addition will change rendering.  Specifically if you use the CSS:

li {display: inline}

The first case renders in a browser as "item1item2" and the second case "item1 item2"

Steps to reproduce:
Parse a document with <li> elements with no whitespace between the elements.  The parse will include inserted whitespace.

Actual results:


Expected results:
There shouldn't be any included whitespace; the parse shouldn't change the document.

Does this happen every time?
Yes.
