[gtkada] reading Xml with Glib.xml

[David C. Hoos, Sr.]

After the call to Parse, rootNode points to the node <users>.

Since Next gets the next sibling (or "brother") node, there are
no siblings of <users>, so the loop terminates.

If you want to look at all of the <user> nodes, you must first
point to the first child of the rootNode, then loop while
the next node pointer is not null.
