use XSLT Preference in Responsive HTML5

Hi

When I publish with Responsive HTML5, framemaker don't use my XSLT Preference preprocessing.

How can i do that?

i need to transform sommething like that :

<tag1>
<tag2 />
<tag2 />
</tag1>

into

<table>
<tbody>
<row>
<entry><img/><tag1><entry/>
<entry><tag2><tag2><entry/>
</row>
</tbody>
</table>

I don't know is there is another solution...

Thanks
