recursive func in XSP?

[Neeme Praks <ne...@one.lv>]

Is it possible to write recursive functions in XSP that would return
XML?

I have a tree-like object structure in Java and I want to convert it to
tree structure in XML.
I have an implementation of this in ECS, now I'm porting my stuff over
to XSP and want to output XML instead of ECS elements.
The function is in the beginning of my XSP page.

Otherwise everything is pretty straight-forward, but what type should my
function return so the resulting XML fragment would be included in the
main XML doc?

As I'm just starting out with XSP, any pointers in the right direction
appreciated.
(I know the links to the new and old XSP tutorials, but this was not
included there)

6 of one, 1/2 dozen of the other. i guess i just don't like relying on
XSP's built in and not documented very well variables.

which actually mine would do as well :-)

it should be
Element e = yourMethodCall();
xspCurrentNode.appendChild(document.importNode(e));

I thought that would give a parent document error unless you pass the page's
Document object into the method...

or, even simpler:

<xsp:expr>yourMethodCall()</xsp:expr>

Element is fine too. Then in your XSP, use this:

Element e = yourMethodCall();
xspCurrentNode.appendChild(e);

org.w3c.dom.Node should work fine.

What is the input to this function going to be?  String, Object, Map??
