How to validate an Xml doc with XSD

[Gilles Lambert]

Hi, i'm trying to validate a doc.xml against a schema XSD this way, but
it doesn't validate anithing :

Dim xrs As New XmlReaderSettings
xrs.Schemas.Add("urn:mediatheque-lrvb8", "schema.xsd")
xrs.ValidationType = ValidationType.Schema

AddHandler xrs.ValidationEventHandler, AddressOf Validation

Dim xr As XmlReader = XmlReader.Create("doc.xml", xrs)

Using xr
Do While xr.Read
Loop
End Using

The EventHandler is never called : i just put any tag, just keeping the
xml doc well formed and nothing appens ?

Thanks and best regards.
Gilles

Here is a complete example from the .NET 2.0 quick start samples
<http://66.129.71.130/QuickStartv20/util/srcview.aspx?path=~/howto/samples/Xml/ValidationReadingXml/ValidationReadingXML.src>
perhaps that helps.

If not then consider posting enough of your code that we can reproduce
what you are doing, we need to see the XML input and the schema.

Hi Martin,

My pb came from the xmlns attribute i ommited in the xml file : it's
mandatory (and not very well explained in the doc !).

Thanks for your answer, and for the Url i visited on www.asp.net :
simply great !!!

Best regards
Gilles
