Re: recursion questions

Didn't get a chance to answer some of your specific questions. However, the
one possibility for the exp/coll "tree" list is XTree mentioned here a few
days ago.

I'm working with it now and although the XSL and XML seem to be tightly
coupled, I think there's potential to decouple them.

I am having a problem understanding how to build some JavaScript for an
exandable/collapsible list similar to a directory tree.  If anybody can
help
it would be greatly appreciated.  I could include what I have been trying
XSL-wise but it would probably be more distractive to the end goal.  I
cannot figure out how to build a recursive template to handle the following
XML (the desired output follows):

<section role="level1" folder="root" label="Test">
     <page id="1"/>
    <section role="level2" folder="XSLXML" label="XSL/XML">
         <page id="2"/>
         <section role="level3" folder="XML" label="XML">
             <page id="3"/>
             <page id="4"/>
        </section>
        <section role="level3" folder="XSL" label="XSL">
             <page id="5"/>
              <page id="6"/
        </section>
    </section>
    <section role="level2" folder="JSDHTMLCSS" label="JS/DHTML/CSS">
       <section role="level3" folder="JS" label="JS">
        </section>
       <section role="level3" folder="DHTML" label="DHTML">
       </section>
       <section role="level3" folder="CSS" label="CSS">
       </section>
    </section>
</section>

DESIRED OUTPUT
-------------------------------------
   root = new List(true, width, height, bgColor);
   root.setFont("<FONT FACE='Arial,Helvetica' SIZE=-1'><B>","</B></FONT>");
     root.addItem("page id=1");
     XSLXML = new List(true, width, height, "#EEEEEE");
     XSLXML.onexpand = colorize;
     XSLXML.setFont("<FONT FACE='Arial,Helvetica' SIZE=-1'>","</FONT>");
       XSLXML.addItem("page id=2");

       XML = new List(false, width, height, bgColor);
       XML.onexpand = colorize;
       XML.setFont("<FONT FACE='Arial,Helvetica' SIZE=-1'>","</FONT>");
       XML.addItem("page id=3");
       XML.addItem("page id=4");

XSLXML.addList(XML, "XML");

       XSL = new List(false, width, height, bgColor);
       XSL.onexpand = colorize;
       XSL.setFont("<FONT FACE='Arial,Helvetica' SIZE=-1'>","</FONT>");
       XSL.addItem("page id=5");
       XSL.addItem("page id=6");
XSLXML.addList(XSL, "XSL");

root.addList(XSLXML, "XML/XSL");

     JSDHTMLCSS = new List(true, width, height, "#EEEEEE");
     JSDHTMLCSS.onexpand = colorize;
     JSDHTMLCSS.setFont("<FONT FACE='Arial,Helvetica'
SIZE=-1'>","</FONT>");

       JS = new List(false, width, height, bgColor);
       JS.onexpand = colorize;
       JS.setFont("<FONT FACE='Arial,Helvetica' SIZE=-1'>","</FONT>");
       JS.addItem("Some JS stuff");
       JS.addItem("Some more JS stuff");

JSDHTMLCSS.addList(JS, "JS");

       DHTML = new List(false, width, height, bgColor);
       DHTML.onexpand = colorize;
       DHTML.setFont("<FONT FACE='Arial,Helvetica' SIZE=-1'>","</FONT>");
       DHTML.addItem("Some DHTML stuff");
       DHTML.addItem("Some more DHTML stuff");

JSDHTMLCSS.addList(DHTML, "DHTML");

       CSS = new List(false, width, height, bgColor);
       CSS.onexpand = colorize;
       CSS.setFont("<FONT FACE='Arial,Helvetica' SIZE=-1'>","</FONT>");
       CSS.addItem("Some CSS stuff");
       CSS.addItem("Some more CSS stuff");

JSDHTMLCSS.addList(CSS, "CSS");

root.addList(JSDHTMLCSS, "JS/DHTML/CSS");

root.build(width/8,40);
