That's an amazingly long-winded way of writing

<xsl:if test=".!=''">
    	<!--DO SOMETHING-->

but it should work. Provided that the test you want is that the element
exists and has a string-value of "". This isn't the same as a test that the
"node has data", for example the element might have attributes and child
elements and still not satisfy this test.
