XSD validation in VB .NET

Hi,

I'm doing validation of a xml file with a xsd schema and it works
fine.

I get validation errors in the form:

=ABMessage:{0} The 'NAM' attribute has an invalid value according to its
data type. An error occurred at file:///A:/myfile.xml, (526, 12).=BB

I can isolate line and column using the args.Exception.LineNumber and
args.Exception.LinePosition properties.

Unfortunately, there is no property to retrieve the element or
attribute name. I have to make a search in the Message string to get
it. And there is no apparent way of getting the value in fault.

Identifying errors is fine but then I need to correct them. I can do
corrections manually using the line and column positions but it's not
very practical for large files.

How can I link the informations given by the XmlValidatingReader to a
dataset or anything that can help me make modifications to correct the
errors ?

thanks

There is, cast the sender argument of your ValidationEventHandler to an
XmlReader and read out the Name property of the XmlReader.

Load into a System.Xml.XmlDocument, that way you get type annotations
(e.g.
<http://msdn2.microsoft.com/en-us/li...SchemaInfo.aspx> )
on the nodes in the XML document and you can manipulate and revalidate
as needed.
