[xsl] How to make tree menu from flat XML

[Radoslav Kolarov <roonex@xxxxxxxxx>]

Hi, I have this XML, and I want to make tree menu. The
roots elements of tree menu are the records with
keynum < -100, the children of the root elements are
records with keynum between -50 and 0 and
parentkeynum=keynum of the root, and the third level
of the tree menu are records with keynum > 0, and the
parentnumber shows the keynum of their parent. Please
help me.
XML file:


<?xml version="1.0" ?>
