Cheers for the feedback.

It's almost working now, just one small problem, the xml data I'm
working on is not sorted. By doing <xsl:sort .. I'm able to sort the
list but it seems that following.sibling::node()[1] doesn't select the
next sorted element but the next element. So for instance when dealing
with computer element with number equals 1, it looks to the next
sibling element which in the xml file is computer element with number
equals 161 and not the element with number equal 2. See the 'problem'?

Any ideas?

<xsl:for-each select="computer">
	<xsl:sort select="@number" data-type="number"/>
	<a href="#{generate-id()}"><xsl:value-of select="@type"/><xsl:number
value="@number" format="001"/></a>
	<xsl:value-of select="concat(' floor: ', floor(@number div 10))"/>
	<xsl:value-of select="concat(' floor_sib: ', floor(following-
sibling::node()[1]/@number div 10))"/>
	<xsl:value-of select="concat(' floor_num: ', (following-
sibling::node()[1]/@number))"/>
	<xsl:if test="floor(@number div 10) != floor(following-sibling::node()
[1]/@number div 10)">
	           <br/>
         	</xsl:if>
