There will always be other elements, so this never terminates. You need to process a diminishing set of elements on each call. The usual way is to use. > <xsl:param name="nodeset" select="(//w)[1]"/> > <xsl:param name="nextset" select="(//w)[position() > 1]a"/> Incidentally, using //w repeatedly is probably inefficient: set a global variable to //w before you start.
