XMLValidatingReader not Validating

[pabowen]

I am trying to perform a validation of XML files using XSD Schema's. However when I perform the validation it instantly skips right through the line of code without performing any validation. The XML files I am running this against are large (20 MB and larger), so I know it should take a while. I am new to trying this, so it is possible that I am way off mark. If I am please let me know.

I am trying to utilize a schema that is offline, rather than the one detailed in the XML file. I don't know if this is part of my problem.

XML header code

<?xml version="1.0" encoding="utf-8" ?> 
- <TRAINING_COURSE_COMPLETE xmlns:xsi="[URL unfurl="true"]http://www.w3.org/2001/XMLSchema-instance"[/URL] xmlns="urn:com.website.tech.lms.course_complete" xsi:schemaLocation="urn:com.website.tech.lms.course_complete course_complete.xsd">

Here is the c# code performing the validation

private void btnValidate_Click(object sender, System.EventArgs e)
{

	string xmlPath = "C:\\Inetpub\\[URL unfurl="true"]wwwroot\\XMLExport\\trng_cse_cmpl.XML";[/URL]
	XmlTextReader Xmlrd = new XmlTextReader(xmlPath);
	XmlValidatingReader Xmlvr = new XmlValidatingReader(Xmlrd);

	Xmlvr.ValidationType=ValidationType.Schema;
	XmlSchemaCollection cache = new XmlSchemaCollection(); 

	string xsdPath = "C:\\Inetpub\\[URL unfurl="true"]wwwroot\\XMLExport\\Course_complete.XSD";[/URL]
	cache.Add("urn:com.website.tech.lms.course_complete", xsdPath); 

	Xmlvr.Schemas.Add(cache);
	Xmlvr.ValidationEventHandler +=new ValidationEventHandler(XmlValidationEventHandler);
			
	try
	{
		Xmlvr.Read();
	}
	catch
	{
		txtMessage.Text = "Error";
	}
	finally
	{
		Xmlvr.Close();
	}

	txtMessage.Text = "Done Validating".ToString();

}

private void XmlValidationEventHandler(object sender, ValidationEventArgs e)
{
	txtMessage.Text = e.Message.ToString();
}

I greatly appreciate any help you can give.

Thanks.
