Subject: RE: [xsl] How to return values from sub-template? From: "Michael Kay" <mike@xxxxxxxxxxxx> Date: Wed, 1 Dec 2004 11:24:02 -0000 |
In XSLT 1.0 your only option is to capture the tree fragment created by the template in a variable using <xsl:variable> <xsl:call-template/> </xsl:variable> XSLT 2.0 provides functions as an alternative to named templates. You can call stylesheet functions from XPath, enabling: <xsl:function name="f">...</xsl:function> <xsl:variable name="v" select="f(....)"/> Michael Kay http://www.saxonica.com/ > -----Original Message----- > From: Matt Adams [mailto:mattad@xxxxxxxxx] > Sent: 01 December 2004 10:45 > To: xsl-list@xxxxxxxxxxxxxxxxxxxxxx > Subject: [xsl] How to return values from sub-template? > > Sorry for this newbie question but I didn't found a hint in > tutorials on how to return > back parameter values from sub-templates.
