16% Actually root is necessarily the element whos UID is 1, by
17% construction. However, xml_parser should return a tree with a ROOT
18% element with as many children as needed but only ONE *element* child
19% who would be the real root (and this method should return the UID of
20% this element).
21
22uid = 1;

24% Update:
25% xml_parser has been modified (not as explained above) to handle the
26% case when several nodes are at the top level of the XML.
27% Example: <!-- beginning --><root>blah blah</root><!-- end -->
28% Now root is the first element node of the tree.
29
30% Look for the first element in the XML Tree
31for i=1:length(tree)
32    if strcmp(get(tree,i,'type'),'element')
33        uid = i;
34        break
35    end
