newbie question: how to insert XSD

[Gennady Khokhorin <go...@aerometric-ak.com>]

Hello, all.
I was trying to create a template from scratch.
Can not insert <?xml-stylesheet tag before the root element, its appear
at the end of xml after root element closing tag. Code is like that:
 
XERCES_CPP_NAMESPACE_QUALIFIER DOMDocument* doc = impl->createDocument(
                           NULL,			// root element
namespace URI.
                           _T("metadata"),	// root element name
                           NULL);			// document type
object (DTD).
DOMProcessingInstruction* procInstruction =
doc->createProcessingInstruction(_T("xml-stylesheet"),
_T("type=\"text/xsl\" href=\"my.xsl\""));	
doc->appendChild(procInstruction);

Hope it is not a bug. 

Also, what command can insert XSD location in the root element like
that:
<metadata xmlns="..." xmlns:xsi="..." xsi:schemaLocation="my.xsd">

Waiting for any help.

Thank you.

No, it's not a bug.  Creating the document also creates the document 
element, and then you "append" a child processing instruction node.  You 
need to use DOMNode::insertBefore() to insert before an existing child.

You need to add the appropriate attributes to the document element.  See 
DOMElement::setAttributeNS() for more information.

Please consider reading a tutorial on the DOM before posting generic 
questions.  A good tutorial will answer many of your questions, and save 
lots of bandwidth on the list.
