xsl:for-each select

xsl:for-each select erlaubt eine effiziente Programmierung auf Basis komplexer, klar definierter Datenstrukturen, die sich beispielsweise aus verschachtelten Datenbankabfragen ergeben. Ein hilfreicher Trick ist auch der Loop allein um das Root-Element.

Das erste Beispiel listet lediglich alle Ortsnamen aus dem XML-Quelldokument auf. Das xsl:template match='/' definiert das Ausgabedokument mit HTML-spezifischen Tags; an passender Stelle wird über eine XSL-Schleife eine Liste aller Ort -Knoten angesprochen, die über XPath definiert werden kann. Mit xsl:value-of select wird dann der Inhalt eines Elements ausgelesen, der wiederum über XPath definiert werden kann, hier: der Childnode name von jedem Ort.
