The saxon:parse() extension function allows you to extract the content of
the comment and parse it as if it were an XML document.

> 
> Hi,
> 
> I'm using XSLT 2.0 with Saxon 8B.
> 
> My problem is:
> I have xml files which contain Arbortext Math markup which 
> has been placed 
> 
> in comments, e.g. 
> <!--<FORMULA><F>-21.6&amp;lt;M<INF>V</INF>&amp;lt;-14.9</F></F
> ORMULA>-->
> The reason being that the math markup is not valid according 
> to the DTD being used. I have no control over this. However, 
> I want to be able to process this "hidden" markup as if it 
> were real elements.
