I would build a variable like this
<xsl:variable name="elements" select="//element[normalize-space()]" />
<!-- all elements whose normalized string value is not the empty string -->

After that replace all //element and ../element in your code with $elements.
Haven't tested this, but I think it should work.

> <xsl:variable name="t-size" select="count(//element)"/>
> <xsl:variable name="half" select="ceiling($t-size div 2)"/>
> 		   
> <table>
> 	<xsl:for-each select="//element[position() &lt;= $half]">
> 	<xsl:variable name="here" select="position()"/>
> 	<tr>
> 		<td>
> 			<xsl:value-of select="@id"/>
> 		</td>
> 		<td>
> 			<xsl:value-of select="."/>
> 		</td>
> 		<td>
> 			<xsl:value-of select="../element[$here+$half]/@id"
> />
> 		</td>
> 		<td>
> 			<xsl:choose>
> 				<xsl:when test="../element[$here+$half]">
> 					<xsl:value-of
> select="../element[$here+$half]"/>
> 				</xsl:when>
> 			</xsl:choose>
> 		</td>
> 	</tr>
> 	</xsl:for-each>
> </table>

Cheers,
Oliver
