cannot load schema for the namespace

[Ian Emery]

Hi,
I am trying to validate an XML file using the XmlValidatingReader and
XmlUrlResolver.
The code for which goes like this:

// Read the XML file.
XmlTextReader xmlReader = new XmlTextReader( _PathToXMLDoc);

XmlValidatingReader valReader = new XmlValidatingReader(xmlReader);
valReader.ValidationType = ValidationType.Schema;

XmlResolver xRes = new XmlUrlResolver();
valReader.XmlResolver = xRes;
valReader.ValidationEventHandler += new
ValidationEventHandler(this.ValidationCallBack);

while(valReader.Read())
{

}

I have the XML document which refers to a xsd file located on a directory
on the local workstation.
If my XML document has the attribute:
xsi:schemaLocation="20040518 C:\Inetpub\wwwroot\20040518.xsd">
then the validation suceeds.
But if I were to change the attribute to:
xsi:schemaLocation="20040518 http://localhost/20040518.xsd";>
I get the error:

"Cannot load schema for the namespace '20040518' - Specified argument was
out of the range of valid values.
Parameter name: The specified value must be greater than 0."

I am able to view the XSD file in IE using the URL
http://localhost/20040518.xsd, hence I know that the XSD file is present and
the IIS is configured correctly.

Any ideas as what's causing this error?

Can you provide your schema and XML instance so the problem can be tracked
down. It seems unlikely that this is simply due to schema location issues.

can you give me a valid email address to send the xml to, the zipped file is
12K and too big for the newsgroup :(
