Subject: Re: [xsl] Passing parameters to an indirectly called template after matching. From: Kannan <riderchap@xxxxxxxxx> Date: Thu, 17 Apr 2008 08:12:49 -0400 |
Thank you Michael and Abel. I got it working with 2.0. I think I will start using XSLT 2.0. The infinite loop solved when I gave a default value for the parameter, very novice to XSLT to know why, but its working now. -Kannan On Thu, Apr 17, 2008 at 7:54 AM, Abel Braaksma <abel.online@xxxxxxxxx> wrote: > Kannan wrote: > > > Can I pass parameters like this. > > > > Calling_Point => A_Named_Template, do apply-templates => {One or more > > matching Templates } => A_Named_Template. > > > > I tried to do this by passing parameters along with apply-templates, > > and then passing it again from all matched templates to a named > > template where I finally need it, it ended up in infinite loop.
