How to preserve Empty XML Tags after XSLT - prevent collapsing them from <B></B> to <B/>
Ok, so here what worked for me:
<xsl:output method="html">
Try this:
<script type="..." src="..."> </script>
Your HTML output will be:
<script type="..." src="..."> </script>
The   prevents the collapsing but translates to a blank space. It's worked for me in the past.
There is no standard way, as they are equivalent; You might be able to find an XSLT engine that has an option for this behaviour, but I'm not aware of any.
If you're passing this to a third party that cannot accept empty tags using this syntax, then you may have to post-process the output yourself (or convince the third party to fix their XML parsing)
