Hello Lech,

XForms doesn't deal with recursion but XPath helps! ;-)

If you use <xf:repeat nodeset="/descendant::*">, you can access all the 
elements in the tree order.

Using this, I wrote a basic XML editor with my own XForms implementation 
(XSLTForms) which I demonstrated at MarkLogic Demo Jam at XML Prague 2011.

Regards,

-Alain
