Re: [xsl] Is a variable referencing a node

[Wendell Piez <wapiez@xxxxxxxxxxxxxxxx>]

Hi,

To add to what others have said, here is how the OP can fix his 
problem. (Apologies if this flew by and I didn't see it.)

xsl:when test="string($foo)" will test as Boolean false when the RTF 
has a string value of "", and true when it doesn't.

Cheers,
Wendell
