Validate xml file

[Guest]

Can I validate an XmlDocument against an xsd file before it is saved to a
file? Any sample code?

I can't see any validated writer code, but you could perhaps use a
reader to parse the XmlDocument? Something like (untested - concept
only):

XmlDocument doc = null; // TODO: something else
XmlReaderSettings settings = new XmlReaderSettings();
settings.Schemas.Add("urn:my-schema", "books.xsd"); //
TODO: your schema
XmlReader reader = XmlReader.Create(new
XmlNodeReader(doc.DocumentElement), settings);
reader.MoveToContent(); // unsure if needed
reader.Skip(); // according to MSDN performs subtree
validation

May also need:

settings.ValidationType = ValidationType.Schema;
settings.ValidationEventHandler += SomeEventHandler;
