I just updated to the newest version of jtidy which came out in october and it seems to have broken my document object for unknown reasons. This is my code:
tidy = new Tidy();
tidy.setShowWarnings(false);
tidy.setShowErrors(0);
tidy.setQuiet(true);
tidy.setMakeClean(true);
URL url = new URL(url_string);
Document doc = tidy.parseDOM(url.openStream(), null);
String xpath_string = "//table[@id='links']//a";
XPath xpath = XPathFactory.newInstance().newXPath();
XPathExpression expr = xpath.compile(xpath_string);
NodeList n = (NodeList)expr.evaluate(doc, XPathConstants.NODESET);
And this is the error I am getting:

The error occurs at the last line of code when trying to generate the NodeList. Has anyone had issues like this with the new version of JTidy?
Had a similar problem. Found a rather silly workaround (to re-parse the jtidy output) that suggests a problem with jTidy.
document = tidy.parseDOM(rstream, null);
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
DocumentBuilder db = dbf.newDocumentBuilder();
ByteArrayOutputStream outputStream = new ByteArrayOutputStream();
Source xmlSource = new DOMSource(document);
Result outputTarget = new StreamResult(outputStream);
TransformerFactory.newInstance().newTransformer().transform(xmlSource, outputTarget);
InputStream is = new ByteArrayInputStream(outputStream.toByteArray());
Document doc = db.parse(is);
It took me hours; hope this helpes.
