Validate document starting at xpath

Question

Hi, I have an issue where I am trying to validate an xml document, but there is header information that I don't want it to validate. So I want to be able to tell it to start validating at a certain xpath location.
xpathExpression contains the xpath link, but it seems to ignore it.
try {
              DOMSource domSource = new DOMSource(doc, xpathExpression);
                StringWriter writer = new StringWriter();
                StreamResult result = new StreamResult(writer);
                TransformerFactory tf = TransformerFactory.newInstance();
                Transformer transformer = tf.newTransformer();
                transformer.transform(domSource, result);
                String docString = writer.toString();
              SAXBuilder builder =
                new SAXBuilder("org.apache.xerces.parsers.SAXParser", true);
                      builder.setValidation(true);
              builder.setFeature(
                "http://apache.org/xml/features/validation/schema",
                true);
              builder.setFeature("http://apache.org/xml/features/validation/schema-full-checking", true);
            builder.setProperty(
                      "http://apache.org/xml/properties/schema/external-noNamespaceSchemaLocation",
                         new File(validationPath).toURI().toString());
            org.jdom.Document docx = builder.build(new StringReader(docString));
            this.wrong(rowCount,1, docString);
            catch (Exception ex){
                 this.wrong(rowCount, 2, ex.getMessage());
                 error = true;
            }I also am having a hard way figuring out how to make sure the document is validated properly.

Then you should work on getting a document validated first, before trying more complicated things like your question. Don't attempt two things at once unless you're sure that at least one of the things isn't going to be problematic. Otherwise you won't know which of the things is a problem.
I am pretty sure it is validated, as I am using error checking and nothing is coming back negative, but is there a way to check to see if the validation was a success?
