Re: [xsl] Help Stepping through XML nodes back and forward

Ok Heres a better explanation of my problem(hopefully):

I have a list of pages/sub pages and from ASP im passing the variable
'PageTCM' (the current page identifier) to the XSLT transformation.

I then need the XSLT to
1. Order the pages in the XML - using the 'order' attribute.
2. Find the current page in the ordered list.
3. Return the Next Page's filename and title attributes. - checking
that it is published first
4. Return the Previous Page's filename and title attributes. -
checking that it is published first.


NB. Being a XSLT novice I should point out that Im not sure that the
above is the most efficient order of events (should I find the current
page first then order only the pages in its group as opposed to
ordering all pages).


Thanks and Regards
Paul

Inputs:
1. strCurrentPage = "tcm:Info"

Outputs:
1. strNextPagePath  = "company/sales.asp"
2. strNextPageTitle = "Sales"
3. strPreviousPagePath = "company/index.asp"
4. strPreviousPageTitle = "Our Company"
