I have an XmlDocument loaded from an xml file. I have also an xsd schema file
associated with it so that it will be in the XmlSchemaSet.
How do I get the data type for the value of an XmlElement and XmlAttribute
as described in the schema while I am accessing the nodes (attributes and
element) in the XmlDocument?

That is possible in .NET 2.0, see the property SchemaInfo

Is there any support in .Net to get the value (for both attribute and
element) in its defined types?
The value for XmlAttribute alway gives a string for example. If it is
defined as an interger in xsd, I would like to get it as an interger. Or I
have to write my code to convert it for every types from string.

If you use an XPathNavigator over the XmlDocument, then you can get typed
values (typed according to the schema) using the following properties on the
navigator:
TypedValue Property
ValueAsBoolean Property
ValueAsDateTime Property
ValueAsDouble Property
ValueAsInt Property
ValueAsLong Property

Thanks,
Priya
