Unfortunately, unless Matt has stripped whitespace, there may be some whitespace around to throw this off. So:
<xsl:if test="normalize-space(.)">....</xsl:if>
(But to avoid copying the empty nodes, Matt's going to have to traverse step-by-step only copying the ones that have non-empty string values ... no copy-of. Time for modes!)

Doesn't xsl:value-of look for the first text content all the way down the whole branch? If so, you could test like this:
