Die Funktionen substring-before() und substring-after() ben?tigen jeweils zwei Argumente. Das erste Argument ist die zu durchsuchende Zeichenkette. Das zweite ist ein Stopp-Wort. Die Funktion substring-before() liefert alles aus Argument eins zurück, was vor dem Stopp-Wort liegt, w?hrend substring-after() alles liefert, was hinter in dem Stopp-Wort liegt. Die Funktion substring() ben?tigt insgesamt drei Argumente. Argument eins: Die zu durchsuchende Zeichenkette. Argument zwei: Ab welcher Position der Teil-Zeichenkette beginnt. Argument drei gibt an, wieviele Zeichen entnommen werden sollen. Wird das dritte Argument nicht definiert, erstreckt sich der Teilstring bis zum Ende des in Argument eins übergebenenen Zeichenkette. Gez?hlt wird ab 1. ( XSLT Stylesheet 1 ). XSLT Stylesheet 2 zeigt eine Situation in der einige Argumente au?erhalb des Bereiches liegen oder keine Integrale sind. Die zurückgelieferte zeichenkette beinhaltet nur die Zeichen deren Position gr??er oder gleich dem zweiten Argument sind -- und w?re ein drittes Argument spezifiert, nur die Zeichen, deren Position kleiner der Summe der Argumente zwei und drei w?ren.
