This still only checks the current node.  I need to be able to traverse
down the tree and remove empty elements from any child node as well.

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:

<xsl:variable name='is-there-any-text'>
    <xsl:value-of select='.'>
</xsl:variable>

<xsl:if test='$is-there-any-text !=""'>....</xsl:if>

Sorry all those quotes are hard to read, just get them to nest right.
