have been trying things out and found an interesting article at

http://support.microsoft.com/kb/307379/EN-US/

but somehow, the code given prompted me more errors than i can understand, making the whole thing useless. Any other better recomendation?

One thing from the article made me think for a while. Is it a must that the link to an xsd file have to be stored inside the xml file?

Validate xml with schemas... try this :)

string strPath = Application.StartupPath + @"\Sample.xml";

XmlSchema schema = XmlSchema.Read(new XmlTextReader(Application.StartupPath + @"\Sample.xsd"), null);

// define handler for compile errors

ValidationEventHandler handler = new ValidationEventHandler(this.CompileErrors);

try

reader = new XmlTextReader(strPath);

valid = new XmlValidatingReader(reader);

while (valid.Read())

// endless loop to read

catch (Exception ex)

finally

reader = null;

valid = null;

schema = null;

If you have link the XSD file from the XML file appropriately, then when you validate using XmlValidatingReader, you don't have to add the schema anymore.

The following line is unnecessary if you have the link.

valid.Schemas.Add(schema);
