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

[Michael Olszynski <m.olszynski@xxxxxxxxxxxxx>]

Hi Jeni

you are so great, I love you!!!! You´re right. Another template made the 
"wrong" recursion. Now everything is working fine.

One more question. Is it possible to find out in which level of topic I am?
The thing is, that I have 4 levels, The 4th level has to get another 
hyperlink, because the 4th level is not a single page, it is the whole 
accumulation of the 5th level topics is in one page, with html ancers.

position()=last() doesn´t work, because, if I only have 2 topics in each 
other, the last topic element is not an element of the 4th level. So how 
can I find out that I´m in level 4 of the nested topic elements.

Thank you

Take care Michael
