Re: [xsl] How to use a JavaScript variable in an XSL template?

[Ryan Scott Bardsley <bardsley@xxxxxxxxx>]

Hi Michael, thanks, that is very helpful. Is there a way to read a variable
stored using the HTML5 local storage model and XSLT? Any examples for invoking
an XSLT transformation from JavaScript?

You are correct, I am not doing it the way you suggested. I am open to any
suggestion on how it can be done better! The majority of the site is in HTML5
and uses JavaScript to read a million localStorage variables.

My problem is with a single case. Argh.

Thanks!

Ryan
