XML Question

[Bridger Maxwell]

Hey,
  I was just debugging the project I have been working on (with all of your
help) and it kept getting erratic results.  I ran my XML through a parser,
and it came up with several errors.  I think I had a giant misconception
when making this project.  Is the following legal:
<Object>
    <Object>
        <Object>
        </Object>
    </Object>
<Object>

In other words, can nodes with the same name be nested within each other?
The parser keeps claiming that it expected the end of the Object node every
time it encounters another Object node within the first.  Does this mean
that I did it all wrong?

  Thank You,
  Bridger Maxwell
