folowing sibling
Please could u explain to me what this line means because i dont really understand what it does, more specifically not sure what ".|follwing-sibling::ve" means??

<xsl:key name="threedots" match="ve" use="(.|following-sibling::ve)[string-length(@pos)=3+string-length(translate(@pos,'.',''))][1]/@pos"/>

This is a fairly standard grouping problem, it would be easier in xslt2
but in xslt 1 you want to use keys as explained on Jeni's site.

In your case you want to group things based on the following ve with
three . in its pos attribute so your key is

<xsl:key name="x" match="ve"
use="(.|folowing-sibling::ve)
[string-length(@pos)=3+string-length(translate(@pos,'.',''))][1]/@pos"/>


then something like (untested)

<xsl:for-each
select="ve[string-length(@pos)=3+string-length(translate(@pos,'.',''))]">
<tr>
<xsl:for-each select="key('x',@pos)">
<td><xsl:value-of select="."/></td>
</xsl:for-each>
</tr>
</xsl:for-each>
