preceding/following sibling

[Mattio Valentino <xmlhack@hotmail.com>]

I'm assuming this is an appropriate venue to ask an XSL question.  If it's not, please let me know and I'll try elsewhere...

 

I'm new to the XML arena, so bear with me if I'm not asking the right question here.  Using an XSL file, I'm trying to create links to other points in an XML document (ultimately, the data's displaying in HTML via JSP).  The problem is that my code works only within the context node.  The link should move from section to section, and the section elements appear within various chapters. The section to section part works, but once it reaches the end of a chapter, it won't move to the next chapter.  Code snippets are below. 

 

Any help/advice is *greatly* appreciated!  Thanks in advance!
