Re: [xsl] recursive call of template - how to find parents

[Michael Olszynski <m.olszynski@xxxxxxxxxxxxx>]

Hi Jeni,

that was such a good idea, I wasn´t familiar with iteratring along axes. 
That´s really great. One thing happens. If I use your topic template, 
everything is working fine, except that the top most elements of the 
sitemap don´t get a href. (in the html-file)
It is that way, because I still used my old sitemap template, which you 
recommended to replace with the sitemap template you wrote. So I did 
replace also the sitemap template. And now, I get a stack overflow 
error, when I try to generate the homepage.

You wrote that I should come up with a more targetted path. Do I have to 
change anything therefore in my xml-file?

Thanks a lot!
I appreciate your help!!!!

Take care Michael
