DOM Parser

[Je Th]

Evry Example I have tried to validate a xml file to a dtd are based on that the user want to parse a file. What if i want to parse and xmldocument from that hasnt been written to the hd yet? I have methods for create a DOM-object and a method for writing it to a file. Im trying to use this code from the faq to parse my to-be-xml-file but i cant get it to work

 public void checkXML (String pathToXML) {
DOMParser parser = new DOMParser();
Document doc = null;
 
try {    
parser.setFeature("http://xml.org/sax/features/validation", true);     
parser.setFeature("http://apache.org/xml/features/validation/schema", true);     
parser.parse("data.xml"); // <--- Here i want to parse a doc, not file    
doc = parser.getDocument();
} catch (IOException e) {    
System.out.println("Could not read file: " + e.getMessage());
} catch (SAXNotRecognizedException e) {    
System.out.println("Feature not recognized: " + e.getMessage());
} catch (SAXNotSupportedException e) {    
System.out.println("Feature not supported: " + e.getMessage());
} catch (SAXException e) {    
System.out.print("Parsing XML failed due to a " + e.getClass().getName() + ":");    
System.out.println(e.getMessage());
}    
} 

could anyone help me or point me to the right direction.

Moving this to the XML forum...

parser.parse("data.xml"); // <--- Here i want to parse a doc, not file

Could you elaborate on this (if "doc" means org.w3c.dom.Document, it is already parsed...)?
For example, do you want to do
- parse("<?xml version='1.0'?><root><foo/><bar>...</bar></root>");
- parse(java.io.InputStream)
- something else?

I want the source to be non-physic-file. I tried do type, parser.parse(MyDocument) where myDocument is the result of

 DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
            DocumentBuilder builder = factory.newDocumentBuilder();
            myDocument = builder.parse("mybuddies.xml")[ 

The scenario is that i want to validate a xmldoc to a DTD before i write it down in a file. Accrding to my resources the parse-method only accepts, File, URL resource, InpuStream & String data. So here is the deal really basic.
1. Load xml-flie from hd
2. Add more info to it
3. Validate old info + new info with a dtd
4. If sucessfull then write it down to a file on the hd.
Im done with all taks accept number 3. Validating the new document against a DTD.
Thanks for your time..

You could combine this and this to produce an in-memory XML file including a DOCTYPE declaration, and then parse it like this.
It's a bit ugly, but should work.
