Figuring out errors during XML validation

[PBR]

How can I capture the Element name, and generate meaningful error
messages, when a validation error occurrs.I am using java APIs to
validate (javax.xml.validation)

You can use methods such as exception.getMessage(),
exception.getLineNumber etc.to get information about an exception.

I'd recommend using the ErrorHandler interface if you're using an
XMLReader.

Steve Thanks for ur reply.
will i be able to get the element name where validation error had
occured if i use exception.getMessage(),exception.getLineNumber..?can u
give an example? (I am using ErrorHandler interface)

Um, yeah I'm fairly certain it gives a validation error message which
includes the element name, I'm sorry I don't have any examples to hand
but try something along the lines of:

class ParserErrors implements ErrorHandler
{
public void warning (SAXParseException e)
{
System.out.println("Warning!, Line: " + e.getLineNumber() +
"\nMessage: " + e.getMessage);
}

public void error (SAXParseException e)
{
etc....
}

public void fatalError (SAXParseException e)
{
etc...
}
}


and just try validating an invalid XML file and see what it gives you.
There are other methods available as well such as getColumnNumber(),
just take a look at the API. Use can use the results of these methods
in any way you want.
