OK, here is an example. XML: <top> <B>B1</B> <A>A1</A> <A>A2</A> <B>B2</B> <B>B3</B> <A>A3</A> <A>A4</A> <B>B4</B> </top> XSL: <xsl:template name="selectNodes"> <xsl:param name="doWhat"/> <xsl:choose> <xsl:when test="$doWhat='GiveMeA'"> <xsl:for-each select="//A"> <xsl:value-of select="."/> </xsl:for-each> </xsl:when> <xsl:when test="$doWhat='GiveMeB'"> <xsl:copy-of select="//B"/> </xsl:when> </xsl:choose> </xsl:template> <xsl:template match="/"> <xsl:text>The A nodes: </xsl:text> <xsl:variable name="A"> <xsl:call-template name="selectNodes"> <xsl:with-param select="'GiveMeA'" name="doWhat"/> </xsl:call-template> </xsl:variable> <xsl:for-each select="$A"> <xsl:value-of select="."/> <xsl:if test="not(position()=last())"> <xsl:text>,</xsl:text> </xsl:if> </xsl:for-each> <xsl:text> and the count is </xsl:text> <xsl:value-of select="count($A)"/> <xsl:text> The B nodes: </xsl:text> <xsl:variable name="B"> <xsl:call-template name="selectNodes"> <xsl:with-param select="'GiveMeB'" name="doWhat"/> </xsl:call-template> </xsl:variable> <xsl:for-each select="$B"> <xsl:value-of select="."/> <xsl:if test="not(position()=last())"> <xsl:text>,</xsl:text> </xsl:if> </xsl:for-each> <xsl:text> and the count is </xsl:text> <xsl:value-of select="count($B)"/> </xsl:template> Why is the output the same (my understanding is that GiveMeA should give me a text node, but I thought that GiveMeB would be a node set)? I want the output to be: "The A nodes: A1,A2,A3,A4 and the count is 4" etc. Thanks, Darren -----Original Message----- Date: Wed, 5 Sep 2001 08:48:39 +0100 From: "Michael Kay" <mhkay@xxxxxxxxxxxx> Subject: RE: [xsl] Returning a Tree > I'm trying to construct a template (call-template) that will > return a node set, and I can't figure out how to do it. > Named templates don't return anything, they write new nodes either to the final result tree or to a "result tree fragment".
