Example

The following example demonstrates how to catch XMLSchemaIntegrityValidationWarning objects during schema validation.

using System;
using System.Xml;
using System.Xml.Schema;

class Program
{
    static void Main()
    {
        XmlReaderSettings settings = new XmlReaderSettings();
        settings.Schemas.Add(null, "example.xsd");
        settings.ValidationType = ValidationType.Schema;
        settings.ValidationEventHandler += ValidationCallback;

        using (XmlReader reader = XmlReader.Create("example.xml", settings))
        {
            while (reader.Read()) { }
        }
    }

    static void ValidationCallback(object sender, ValidationEventArgs e)
    {
        if (e.Exception is XMLSchemaIntegrityValidationWarning warning)
        {
            Console.WriteLine($\"Warning: {warning.Message}\");
            Console.WriteLine($\"Location: {warning.SourceUri} (Line {warning.LineNumber}, Position {warning.LinePosition})\");
        }
        else
        {
            Console.WriteLine($\"Error: {e.Message}\");
        }
    }
}
