Good to hear. Unfortunately, we are using an older version of
XML::Parser (2.22), while XML::Checker requires 2.23 (according to make
test). I'm not going to even try to get this upgraded on the production
site knowing how finicky XML::Parser can be. But I'll definately keep it
in mind should we upgrade in the future. I see our API becoming much
more important in the near future, and this might help get things
upgraded sooner.

I stand corrected. :-) I'll play around with XML::ValidWriter and see
what happens. Of course, I also happen to like the way we generate XML
now. It's just a big array of arrays of arrays... reference that is
walked to make the XML. Pretty neat, and the implementation is actually
very simple.

It also requires a more recent XML::Parser to slurp up DTDs, but DTDs
can be saved as Perl modules and you don't need to load XML::Parser to
use them.

hello

for people using XML::Writer, you can write to a string by using
the IO::String module..


example:

my ($output, $io, $obj);
$io = IO::String->new($output);
tie *IO, 'IO::String';

$obj = new XML::Writer(OUTPUT => $io, DATA_MODE => 1, DATA_INDENT => 1);

.
<code to build xml>
.
.

$obj->end();

print $output;



DESCRIPTION
       The IO::String module provide the IO::File interface for
       in-core strings.  An IO::String object can be attached to
       a string, and will make it possible to use the normal file
       operations for reading or writing data, as well as seeking
       to various locations of the string.  The main reason you
       might want to do this, is if you have some other library
       module that only provide an interface to file handles, and
       you want to keep all the stuff in memory
