[jdom-interest] XMLOutputter and newlines after declaration/doctype

[Vadim Strizhevsky]

Currently (in latest CVS that I had access to) XMLOutputter always
prints out new lines after declaration and DOCTYPE, no matter what the
newline option is set to. There's even comment in the code stating that
this done on purpose because its looks better and is sematically
inconsequential.

I'd like to request an ability to output the whole xml as one line,
without any newlines, (except the final one I guess). Either controlled
by the same flag as other new lines or a separate boolean flag. While I
do agree that having them there is sematically inconsequential, there
are situations and non-semantic reasons when you may want to really have
xml output as a single line. You want doc as small a possible. Or you
want to generating a big log file of multiple xml messages that will
later be processes by scripts. Having the complete message on a single
line would simplify those scripts.

For now I will have XMLOutputter subclass that duplicates
printDeclaration and printDocType methods and doesn't print the newlines
when newline option is set to false.

Also I noticed a signle use  of "\n" instead of lineSeparator in the
latest printDocType code.

Thanks,
-Vadim
