Re: XML Validation of root node
Thanks guys, for helping out.
I find that setting the Feature
"http://apache.org/xml/features/validation/dynamic" to True causes
this problem to happen. If I keep this flag to false, the incorrect
root node is properly identified. If the flag is True, it does not
catch the incorrect root node.
Any idea why this happens?
Here's the code:
SAXParser par = new SAXParser ();
par.setErrorHandler(new ParserErrorHandler()); //
ParserErrorHandler and ParserEntityResolver are trivial classes..
nothing significant there..
par.setEntityResolver(new ParserEntityResolver());
try
{
par.setFeature("http://xml.org/sax/features/validation", true);
par.setFeature("http://apache.org/xml/features/validation/schema",
true);
par.setFeature("http://apache.org/xml/features/validation/dynamic",
true); // This is the problem!!
FileInputStream fis = new FileInputStream
("D:/cdcatalog_invalid.xml");
ProtectedInputStream pis = new ProtectedInputStream(fis);
InputSource is = new InputSource (pis);
par.parse(is);
}
catch (Exception e)
{ }
public class ProtectedInputStream extends InputStream {
private InputStream is;
public ProtectedInputStream(InputStream is) {
this.is = is;
}
public int read() throws IOException {
return is.read();
}
public void close() { // Overridden close function to prevent
Xerces from closing my stream
}
}
Thanks,
Subbu.
