The interface definition classes are decorated with XML serialization attributes that bind the classes to specific namespaces, attributes, and elements in the XSD schema file. Consider, for example, the following: [return: XmlElement("Quote", Namespace = "http://www.bluestonepartners.com/schemas/StockTrader/")] public abstract Quote RequestQuote(string Symbol); This unambiguously states that the RequestQuote operation returns an object of type Quote, as qualified in the http://www.bluestonepartners.com/schemas/StockTrader/ namespace. In fact, this namespace is documented liberally throughout the IDC file. It can never appear too often because XML messages must be as unambiguous as possible. XML and SOAP serialization attributes give you direct control over the way in which the XML messages get serialized within the request and response SOAP messages. You should always set the SoapDocumentMethod reflection attribute to use bare encoding for parameters. This ensures that complex types (such as Quote) remain serialized as elements within the SOAP message: [WebMethod()] [SoapDocumentMethod(Use=SoapBindingUse.Literal, ParameterStyle=SoapParameterStyle.Bare)] public abstract Quote RequestQuote(string Symbol); If you do not use bare encoding, complex types may end up serialized as attributes, which may interfere with schema validation. This is known as wrapped encoding. Bare encoding looks like this <Quote> <Symbol>MSFT</Symbol> </Quote>

You might expect that the state element simply provides a property or method to retrieve the element s text This is not the case The text representing the state s name is actually a child element of the state element In an XML document, text is considered a node unto itself and must be the child of some other element Since the text representing the state s name is actually a child element of the state element, it must be retrieved by first retrieving the text element from the state element and then asking the text element for its textual content The outputList function does just that It iterates through all the elements in the array, assigning the current element to the currentState variable.

while wrapped encoding looks like this <Quote Symbol="MSFT" /> Wrapped encoding will generate fewer XML characters and a smaller SOAP payload, but it may create big problems if custom types cannot be validated against their XSD schema files. Table 3-1 summarizes important properties of the serialization attribute, including how certain property values influence the processing behavior of a Web service.

Because the text element representing the state name is always the first child of the state element, you use the childNodes property to retrieve the text element Once you have the actual text element, the nodeValue property returns the text content representing the state s name..

Reflection attributes allow you to add additional metadata to a wide variety of code elements, including classes and methods. Attributes modify the way that the element is processed. For example, the [WebMethod] attribute designates a standard method or function as capable of accepting serialized XML messages. Of course, reflection attributes must have meaning to the processing code in order to be applied. Reflection attributes may include properties that provide additional metadata information. For more on reflection attributes, consult the MSDN online article on attributes, located at MSDN Home MSDN Library .NET Development Visual Studio .NET Visual Basic and Visual C# Reference Visual C# Language C# Language Specification.

The listNorthStates function is similar to listAllStates except with an added twist. You want only the states that are in the northern region, not all the states. To do this, you first retrieve the north tag using the getElementsByTagName method to retrieve the north element from the XML document. Because the document contains only one north element and because the getElementsByTagName method always returns an array, you use the [0] notation to extract the state element since it s in the first (and only) position in the array returned by the getElementsByTagName method. Now that you have the north element, you can retrieve the state elements that are children of the north element by calling the getElementsByTagName method on the north element. Once you have an array of all the state elements that are children of the north element, you can again use the outputList method to display the states in an alert box.
