Die Funktion position() gibt eine Zahl zurück, die in etwa die Kontext-Position wieder spiegelt. Die last() Funktion gibt die Anzahl der Elemente wieder, die durch die den Auswahl-Kontext ermittelt wurden. XSLT Stylesheet 1 zeigt die Verwendung der beiden Funktionen in verschiedenen Zusammenh?ngen. XSLT Stylesheet 2 vergleicht sortierte und unsortierte xsl:for-each Elemente.
