If I understand you correctly, you want to check whether an element is empty
and not copy it to the result tree if so, right? 

Something like this will do it:

  <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
		 version="1.0">

	 <xsl:template match="*">
		<xsl:if test="normalize-space(.)">
		<xsl:copy>
		  <xsl:apply-templates select="@*|node()"/>
		</xsl:copy>
		</xsl:if>

	 </xsl:template>

	 <xsl:template match="@*">
		<xsl:copy>
		  <xsl:apply-templates select="node()"/>
		</xsl:copy>
	 </xsl:template>


  </xsl:stylesheet>

The first template rule checks whether, after getting rid of extraneous
white space, an element has anything left. If so, it gets copied. (The other
template rule copies the attributes.)

There's more about this in section 3.10 of my book.
