Schemaset : schema compiled form code shows no PSVI elements

[Steve at Pixelda]

I accidentally put this on another group - this is the more likley home...

The first code fragment creates the simplest of XML Schemas is code. After
the “Compile()� method is called on the schemaset objetc, the schema element
count is zero – but I was expecting one element in the PSVI.
I saved the XML output in the console window to a file, and ran the second
code fragment below to load in the XML from the file, and compile the schema.
The element count of the schema is now 1 – as expected.
Why does the compile for a schema created in code not set to schema element
count to 1?

I also tried to add a second element after a schema was loaded from a file
(as in second fragment), but instead of getting 2 elements, scheme just shows
1
First Code Fragment
XmlSchemaSet schemaSet = new XmlSchemaSet();
schemaSet.ValidationEventHandler +=new
ValidationEventHandler(schemaSet_ValidationEventHa ndler);

XmlSchema s = new XmlSchema();
schemaSet.Add(s);

// add an element
XmlQualifiedName e1Type = new XmlQualifiedName("string",
"http://www.w3.org/2001/XMLSchema");
XmlSchemaElement e = new XmlSchemaElement();
e.SchemaTypeName = e1Type;
e.Name = "E1";

s.Items.Add(e);
schemaSet.Compile();

XmlNamespaceManager nsmgr = new XmlNamespaceManager(new
NameTable());
nsmgr.AddNamespace("xs", "http://www.w3.org/2001/XMLSchema");
s.Write(Console.Out, nsmgr);

Second Code Fragment
XmlSchemaSet schemaSet = new XmlSchemaSet();
XmlSchema s = schemaSet.Add(null, @"C:\Temp\CompileTest.xsd");

OK, it looks like you need to call the Reprocess method to build the PSVI.

This method performs the steps that an "Add" schema does - and as a side
effect, sets the IsCompiled to false. I assume from the documentation that
the compile method simply performs validation - without setting the PSVI. I
got a bit confused here. Maybee the documentation needs a bit more
explanation.

The XmlSchemaSet does not track editing of the XmlSchema objects already
added to the set, so in case you add a schema and pick up new additions to
it, you must call Reprocess().

In your case, you dont need to call reprocess if you add the XmlSchema to
the set AFTER making the edits, so move to the line:

schemaSet.Add(s);
below the
s.Items.Add(e);
This should let the set add the XmlSchema with the element added.

Thanks.
