DOMPrint: Declaration and Document Type

I'm trying to use the DOMPrint code to ouput the text of a DOM_Document
that was constructed entirely in memory by adding nodes. Unlike the
DOMPrint example, this DOM_Document was never parsed from XML text.

I find that the declaration text at the start is never written. I mean
this type of stuff:

<?xml version='1.0' encoding='ISO-8859-1' ?>
<!DOCTYPE cacs_configuration SYSTEM "cacs_configuration.dtd">

I've tried using DOM_Document::createXMLDecl(), and
DOM_Document::createDocumentType(), but they don't seem to have any
effect. Can anyone give me any clues?

That did it. I was using DOM_Document::createDocumentType() instead of
DOM_DOMImplementation::createDocumentType(). I'm not sure why the first
one exists, as you generally need a DocumentType before creating the
Document.

At least in C++, it's unnecessary to use
DOM_DOMImplementation::getImplementation(). The DOM_DOMImplementation
constructor is enough.

Thanks.

Murray, 

Are you using DOM_DOMImplementation::getImplementation() ?

This is the interface I use. Pardon the Perl code, but the interface
is the same:

$impl = XML::Xerces::DOM_DOMImplementation::getImplementation();
$dt = $impl->createDocumentType('Foo', '', 'Foo.dtd');
$doc = $impl->createDocument('Foo', 'foo',$dt);

HTH,
jas.
