XmlSchema inferred from an XML file - how to iterate through all the elements in the XSD?

Question

I have an XML file and I\'m inferring its XSD schema in run-time, using the XmlSchemaInference class.

Sample file:

Okay! No answer and not much interest - I figured it out on my own.

I used code from this MSDN article I googled up: Traversing XML Schemas

And I based my recursive solution on it.

void PrintSchema(string xmlFilePath)
{
    var schemaSet = new XmlSchemaInference().InferSchema(XmlReader.Create(xmlFilePath));
    foreach (XmlSchemaElement element in schemaSet
        .Schemas()
        .Cast<XmlSchema>()
        .SelectMany(s => s.Elements.Values.Cast<XmlSchemaElement>()))
    {
        Debug.WriteLine(element.Name + " (element)");
        IterateOverElement(element.Name, element);
    }
}

void IterateOverElement(string root, XmlSchemaElement element)
{
    var complexType = element.ElementSchemaType as XmlSchemaComplexType;
    if (complexType == null) 
    {
        return;
    }
    if (complexType.AttributeUses.Count > 0)
    {
        var enumerator = complexType.AttributeUses.GetEnumerator();
        while (enumerator.MoveNext())
        {
            var attribute = (XmlSchemaAttribute)enumerator.Value;
            Debug.WriteLine(root + "." + attribute.Name + " (attribute)");
        }
    }
    var sequence = complexType.ContentTypeParticle as XmlSchemaSequence;
    if (sequence == null) 
    {
        return;
    }
    foreach (XmlSchemaElement childElement in sequence.Items)
    {
        root += String.Concat(".", childElement.Name);
        Debug.WriteLine(root + " (element)");
        // recursion
        IterateOverElement(root, childElement);
    }
}

The output is:

products (element)
products.product (element)
products.product.id (attribute)
products.product.name (attribute)
products.product.size (element)
products.product.size.name (attribute)
products.product.price (element)
products.product.price.net (element)
products.product.price.gross (element)

I leave to you to judge how friendly this API is, especially given how scarce is the MSDN documentation on these particular classes. Any comments or insights are appreciated.
