<xsl:for-each select="tokenize($s

so here the current item (.) is a string, not a node

so

 <xsl:apply-templates select="site

is selecting the child elements of the string, which isn't what you
want.

Do

<xsl:variable name="here" select="."/>
   <xsl:for-each select="tokenize....
....
  <xsl:apply-templates select="$here/site...
  <xsl:apply-templates select="$here/document...


so you are selecting element children of the original aspect element
where you came into the template.
