Using just the XmlDocument to validate xml against an xsd schema

[John H]

Hi,
How can i just use the XmlDocument object to validate an xml instanace
against a schema referenced inside the xml instance?
The Load method seems to not validate it against the schema.

Thanks
John

There is an overload for the Load method that takes an XmlReader:
<http://msdn.microsoft.com/library/default.asp?url=/library/en-us/cpref/html/frlrfSystemXmlXmlDocumentClassLoadTopic4.asp>
There you can pass in an XmlValidatingReader set up properly which
performs the validation.
With .NET 2.0 there is also a new method called Validate
<http://msdn2.microsoft.com/en-us/library/ms162370(en-US,VS.80).aspx>
which allows you to validate the document after it has been loaded and
manipulated.
