I'm trying get information about an XML document using the schema information. Are there any classes that would make it easy to get information like what elements and/or attributes are valid for a particular element? The only thing I have found so for is the XmlSchemaValidator where I can do incremental schema validation and use GetExpectedParticles and GetExpectedAttributes as I iterate over the xml document. This isn't very convenient since it's tied to parsing and not to the node after the parsing is complete. It would be much better if I could somehow use node.SchemaInfo but I can't seem to find any relevant information in there. Is anyone else doing something similar? How should I be trying to get the available elements/atttributes for a particular element? [Edited by - tstrimp on March 15, 2007 5:07:35 PM]

I figured it out. Here is how I did it in case anyone else wanted to know.

static void Main(){  StreamReader stream = new StreamReader("schema.xsd");  XmlSchema = schema = XmlSchema.Read(stream, null);  stream.Close();  XmlDocument = doc = new XmlDocument();  doc.Load("document.xml");    doc.Schemas.Add(schema);  XmlQualifiedName qualifiedName = new XmlQualifiedName("element-name", _schema.TargetNamespace);  XmlSchemaElement element = _schema.Elements[qualifiedName] as XmlSchemaElement;  XmlSchemaComplexType type = element.SchemaType as XmlSchemaComplexType;  foreach (XmlSchemaAttribute attr in type.Attributes)  {    // Attributes    Console.WriteLine(attr.Name);  }  XmlSchemaGroupBase content = (XmlSchemaGroupBase)type.Particle;  foreach (XmlSchemaElement item in content.Items)  {    // Elements    Console.WriteLine(item.Name);  }  Console.ReadLine();}
