[jdom-interest] setIndent("") doesn't work as expected

[wkrick at eio-online.com]

I'm currently outputting my document with the PrettyFormat...

Format fmt = Format.getPrettyFormat();
fmt.setTextMode(Format.TextMode.PRESERVE);
XMLOutputter outputter = new XMLOutputter(fmt);

...and it works as expected, outputting one start/end tag per line.
However, when I try to remove the indents on each line like this...

Format fmt = Format.getPrettyFormat();
fmt.setTextMode(Format.TextMode.PRESERVE);
fmt.setIndent("");
XMLOutputter outputter = new XMLOutputter(fmt);

...it removes all indents _AND_ newlines, compressing my whole  
document into a single line of output.

I'm confused...

fmt.setIndent("  "); adds a two space indent
fmt.setIndent(" "); adds a one space indent
fmt.setIndent(""); no indent and removes newline on previous line?

I'm suspecting that the problem has something to do with...

fmt.setTextMode(Format.TextMode.PRESERVE);

...but I need that mode to keep padding that's present in my document.


Basically, given a document that looks like this...

<FOO><BAR>    12345</BAR><BAR>    67890</BAR></FOO>

...I need the output to look like this...

<FOO>
<BAR>    12345</BAR>
<BAR>    67890</BAR>
</FOO>

...instead of this...

<FOO>
   <BAR>    12345</BAR>
   <BAR>    67890</BAR>
</FOO>

...but I can't seem to find the magic incantation that works.

Is this possible?
