For this you don't need to increment a counter; you just need to look at the position() of the current node. If when divided by 50 the remainder is zero, add the extra text, like this: <xsl:template match="item"> <xsl:text>item text: </xsl:text> <xsl:value-of select="."/> <xsl:text>
</xsl:text> <xsl:if test="position() mod 50 = 0"> <xsl:text>some extra text</xsl:text> </xsl:if> </xsl:template> > The only things which I've found which look to do this are xsl:counter and > xsl:counter-reset, but these always seem to be unrecognised by whatever > XML/XSL parser I use. There is no counter in XSLT. "xsl:counter" is something Microsoft made up for MSXML1/IE5. You also can't implement a counter in an obvious way, since variables cannot be updated once they are assigned. A named template can be used to generate a result tree fragment that contains a number that is 1 greater than a number passed into it as a parameter. When assigned to a variable, this fragment can be treated like a number in numeric comparisons. For generating numeric text nodes based on things in the source tree, you can use xsl:count. - Mike ____________________________________________________________________ Mike J.
