Extracting all the built-in and Custom Types available in a schema.

[akshaychand]

Hi,

I am designing a Schema Editor using the Schema Object Model in .NET 2.0. I am currently facing an problem wherein I want to list all the built-in data types as well as the custom types that are defined globally in the schema as well as the custom types that are defined globally in all the imported schemas. Basically, I want to list all these types in a drop down so that when user creates a new element or attribute, he can specify that element to be of a certain type by selecting it from a drop down.

for instance:
My schema looks like the following:

 
 <?xml version="1.0"?>
 <xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"
      xmlns:custImport1="http://www.mysite.com/myschema">
 
    <xs:import namespace="http://www.mysite.com/myschema"
      schemaLocation="schema1.xsd"/>
    ...
    <xs:complexType name="AddressType">
        ...
    </xs:complexType>
    ...
 </xs:schema>
 
 

the drop down list could contain something like:
xs:string
xs:decimal
xs:AddressType
custImport1: SSNType

Any help is appreciated.
