Subject: REXML Formatter issue - does each Element need formatting?

All,

Recently upgraded to Ruby 1.8.6 and having some backwards-compatibility
problems with REXML given it's new formatting setup.

Basically, I have a XML document with three elements underneath the
root.  After I completely generate the XML, I use the following code to
pretty-print it out:

    formatter = REXML::Formatters::Default.new
    File.open("#{@file_path}", 'w') do |f|
      formatter.write(@document, f)
    end

What appears to happen, however, is that only the _first_ subordinate
element is pretty - printed, and the rest of the contents of the root
element are printed on one line after the first element ends.

It currently looks like this:

<root_elem>
  <first_elem>
    ...pretty-printed contents of first_elem...
  </first_elem><second_elem>...inline contents of
second_elem...</second_elem><third_elem>...inline contents of
third_elem....</third_elem>
</root_elem>

The consumer of this XML is unable to parse this.  Changing the consumer
is not possible at this point, so I need to fix how this is output.

What I want to see is:

<root_elem>
  <first_elem>
    ...pretty-printed contents of first_elem...
  </first_elem>
  <second_elem>
    ...pretty-printed contents of second_elem...
  </second_elem>
  <third_elem>
    ...pretty-printed contents of third_elem....
  </third_elem>
</root_elem>

My guess is that I will need to write out each element separately with a
formatter, since the formatting of the document that I invoked doesn't
appear to propagate down into each element.

Am I on the right track?

Thanks,
Wes
