Re: HTML/XHTML/HTML5 Serialization Options

I did a little more testing and here's what I found for the input "<br/>"
using Saxon 9.6, just to confirm Mike's assertion about what Saxon does
(and should be expected to do based on the spec):

Input doc: HTML tags with no namespace:

format="html": <br>
format="xhtml": <br></br>

Input doc: HTML tags in XHTML namespace:

format="html": <br></br>
format="xhtml": <br />

Since I want "<br />" in the result clearly I need to have my input HTML
in the XHTML namespace and a format value of "xhtml".

Cheers,


E.
