[xsl] Testing strings for null

OK, I'm a newbie. Please beat me over the head with why this doesn't work:

       <xsl:when test="ASTRING $igt$ 0">
               <xsl:value-of select="ASTRING"/>

I just want to know if ASTRING is null, and I can't seem to figure out what to do. This test comes up False every time.

Thanks, pablos.
