How to validate an XML that I receive in a .asmx Web-service with an xsd?

  • 772

I have a Web-service .asmxthat receives some elements (parameters or attributes) from an XML . This XML is sometimes received without some element.

How can my Web-service return an error notice that X element is missing from the request?

How can I do it by validating it with the XSD ?

c#

    If you're using .NET 3.5 or higher, you can easily validate using XDocumentand XmlSchemaSet.

    Look at this example for the console:

    schemaFileName = @"C:\la\ruta\de\mi.xsd";
filename = @"C:\la\ruta\de\el.xml";
XmlSchemaSet schemas = new XmlSchemaSet();
schemas.Add(schemaNamespace, schemaFileName);

XDocument doc = XDocument.Load(filename);
string msg = "";
doc.Validate(schemas, (o, e) => {
    msg += e.Message + Environment.NewLine;
});
Console.WriteLine(msg == "" ? "El documento XML es válido" : "Documento XML inválido: " + msg);

    More information in the MSDN documentation .
