Try 
<xsl:template match="*" mode="copy-unless-empty">
 <xsl:if test="node()">
  <xsl:copy>
   <xsl:copy-of select="@*"/>
   <xsl:value-of select="."/>
  </xsl:copy>
 </xsl:if>
</xsl:template>

and then use <xsl:apply-templates mode="copy-unless-empty"/>
to process these elements.

A similar technique should do the trick.
