A position() függvény egy számmal tér vissza, amely egyenl? az adott k?rnyezet pozíciójával míg a last() függvény által visszaadott szám az adott kifejezés által meghatározott k?rnyezet méretével egyenl?. Az XSLT stíluslap 1 ezen függvények használatát mutatja be t?bbféle k?rnyezetben. Az XSLT stíluslap 2 a rendezett és rendezetlen xsl:for-each elemeket hasonlítja ?ssze.
