XML Schema validation

I am attempting to validate an xml file against an external xsd using vb.net - I have seen lots of samples, using the XMLValidatingReader, but these are very old postings and this is now deprecated. The postings I have found all use an internally referenced XSD so apart from trying to not use the xmlValidatingReader I need to reference the same external XSD

I am trying to validate xml prior to transforming to different formats. Any help would be appreciated in helping me to understand how to approach this or even to pointing me to tools which will do the talk for me !

Thanks - I live in hope !

I found this out on the web // this is the correct way to validate public static bool ValidateXml(string xmlPath, string XsdPath) { try { XmlReader xsd = new XmlTextReader(XsdPath); XmlSchemaSet schema = new XmlSchemaSet(); schema.Add(null, xsd); XmlReaderSettings xmlReadeSettings = new XmlReaderSettings(); xmlReadeSettings.ValidationType = ValidationType.Schema; xmlReadeSettings.Schemas.Add(schema); xmlReadeSettings.ValidationEventHandler += new ValidationEventHandler(ValidationHandler); //XmlTextReader xmlTextReader = new XmlTextReader(xmlPath); //XmlReader xmlReader = XmlReader.Create(xmlTextReader, xmlReadeSettings); XmlReader xmlReader = XmlReader.Create(xmlPath, xmlReadeSettings); while (xmlReader.Read()) ; xmlReader.Close(); } catch (Exception ex) { isValied = false; // Write here exception massage to log } return _isValied; }
