Correct - that's the only way I've found of incrementing - via recursion.

Wouldn't something like this (admittedly ad hoc, untested code) work too? <xsl:template match="docroot"> <xsl:variable name="var">1</xsl:variable> <xsl:apply-templates select="a[1]" mode="tailRecurseSibs"/> </xsl:template> <xsl:template match="a" mode="tailRecurseSibs"> <xsl:param name="var" select="1"/> <xsl:value-of select="$var"/> <xsl:apply-templates select="following-sibling::a" mode="tailRecurseSibs"> <xsl:with-param name="var" select="$var + 1"/> </xsl:apply-templates> </xsl:template> In other words, while direct iteration using a variable will not allow the desired operation, tail recursion using a parameter should.
