How to convert Document object to Input Source?

Question

I am having a XML document objecy created on the fly. I need to validate it against Schema. I am using xerces 2. I have set features for the parser.Now i need to parse to validate the XML.

For this i need to call "parser.parse()". But parse() method takes "InputSource" as parameter. But i have Document object. How do i convert this Document object to "InputSource" for passing it to parse() method.

Can anybody help.

Best Regards,

ByteArrayOutputStream docOutputStream = new ByteArrayOutputStream();
((XmlDocument)domDocument).write(docOutputStream);
ByteArrayInputStream docInputStream = new
ByteArrayInputStream(docOutputStream.toByteArray());
InputSource inputSource = new InputSource(docInputStream);
parser.parse(inputSource);
