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.vali dation)

You can use methods such as exception.getMe ssage(),
exception.getLi neNumber 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.getMe ssage(),excepti on.getLineNumbe r..?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 (SAXParseExcept ion e)
{
System.out.prin tln("Warning!, Line: " + e.getLineNumber () +
"\nMessage: " + e.getMessage);
}

public void error (SAXParseExcept ion e)
{
etc....
}

public void fatalError (SAXParseExcept ion 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.

A web application of mine developed using C# + MS SQL runs fine normally. However when I stress test it with a load testing software (using about 60 simultaneous users) some instances start erroring out. I see two different errors. One is a "Object reference not set to an instance of an object." error, which appears to always contain the same information, and the other is a "There is no row at position X.", where X is a number. Is this...

Can the CustomValidator be used to simply report unexpected errors, without requiring Client/Server validation? To explain, say you had a simple text box and button that did a Full-text Search of a Catalogue in SQL. Malformed search requests can generate a variety of errors, which I simply want to catch, set the CustomValidator's IsValid method to false and assign the ErrorMessage to the CustomValidator's Message property. For example: ...

I have an XML Schema file that I know is correct becuase I currently use it in a VB6 program to validate XML documents. Also, if I load an XML file into VS2005 that is not valid against this schema, I get XML errors (blue squigglies) in a few places, which indicates to me that I should get validation errors while validating through code. When I try to validate an invalid document, I never get any validation errors. I have tried many...

I've been creating an application over the last few weeks and generally pleased with what I have produced but one area is irritating me, form validation. At the moment the forms are simply static html templates and the form input is checked using a validation class. Basically each form field is checked, every error is stored to an array and at the end of checking of the complete form, the array is output neatly at the top of the form. ...
