Is the part http://mywebsite/ fixed and known to the stylesheet?
If yes then you need e.g.

<xsl:key name="smain-by-type" match="smain" 
use="substring-before(substring-after(substring-after(lnk, 
'http://mywebsite/'), '/'), '/')"/>


and e.g.

       <xsl:apply-templates select="main/smain[generate-id() = 
generate-id(key('smain-by-type', 
substring-before(substring-after(substring-after(lnk, 
'http://mywebsite/'), '/'), '/'))[1])]" mode="group">
         <xsl:sort 
select="substring-before(substring-after(substring-after(lnk, 
'http://mywebsite/'), '/'), '/')" data-type="text" order="ascending"/>
       </xsl:apply-templates>

and the same "monster" expressions at the other places. String 
manipulation can get a bit cumbersome in XSLT/XPath 1.0 but you simply 
need to use enough combinations of substring-after and substring-before 
to extract the part you want.
