Okay, I've set up a tree component, populated it with XML and
set up onClick functions to dynamically make an input text box to
change the labels at runtime. The only issue is, I would like my
new dynamic text box to be located over the old label. I can't seem
to find out how far in the clicked node is indented, i.e. how many
levels deep it is in the XML tree. Is there a quick way that I can
see the indentation on a tree node?
