Hi Jon,
If you want to get a list of expected elements (for example, in a sequence
or a choice), you can use XmlSchemaValidator.GetExpectedParticles method
(
http://msdn2.microsoft.com/en-us/lib...particles.aspx)
If you want to get enumeration values for a given element/attribute, you can
use XmlSchemaEnumerationFacet class
(
http://msdn2.microsoft.com/en-us/lib...ionfacet.aspx).
The example below shows how to use XmlSchemaEnumerationFacet to retrieve
enumeration values. "st" here is the (simple) type of your
element/attribute.
if (st.Content is XmlSchemaSimpleTypeRestriction)
{
XmlSchemaSimpleTypeRestriction xsstr = st.Content as
XmlSchemaSimpleTypeRestriction;
foreach (XmlSchemaFacet xsf in xsstr.Facets)
{
if (xsf is XmlSchemaEnumerationFacet)
{
// handle xsf.Value
}
}
}
