Deserializing XML Data to Objects The deserialization process is controlled by the Deserialize method for a variety of sources, including streams, XML readers, and text readers Remember that by using the trick discussed in 2 for XML readers (packing a string into a StringReader object), you can also easily deserialize from strings Although officially you can deserialize from streams and text readers, the deserialization process is actually a matter of invoking an XML reader more precisely, a very special breed of XML reader, optimized for serialization and for the specific class involved Connected to the deserialization process is the Can-Deserialize method This method returns a Boolean value indicating whether the XML reader is correctly positioned on the start element of the XML data In addition, CanDeserialize ensures that the start element of the XML data is compatible with the originally saved class.

Normally, you call CanDeserialize in the context of a more general strategy designed to trap as many errors and exceptions as possible If the application always deserializes data that the XML serializer has previously created, a call to CanDeserialize can easily be redundant The call becomes crucial, how-ever, as soon as your application begins to deserialize XML data whose genuineness and quality are not guaranteed It is worth noting that CanDeserialize works only on XML readers, whereas Deserialize can successfully handle streams and text readers too From a programming perspective, deserializing is not rocket science, as the following code clearly demonstrates: StreamReader reader = new StreamReader(fileName); Employee emp = (Employee) serDeserialize(reader); readerClose(); During the deserialization stage, a few events can be fired In particular, the UnknownElement, UnknownAttribute, and UnknownNode events signal when unknown and unexpected nodes are found in the XML text being deserialized.

The UnknownNode event is more generic than the other two and triggers regardless of the node type on which the exception is detected In case of unknown element or attribute nodes, the UnknownNode event is fired first..

Hooking Up the Deserialization Process The following code demonstrates how to register event handlers for the events described in the previous section: XmlSerializer ser = new XmlSerializer(typeof(Employee)); ser.UnknownElement += new XmlElementEventHandler(GotUnknownElement); ser.UnknownAttribute += new XmlAttributeEventHandler(GotUnknownAttribute); ser.UnknownNode += new XmlNodeEventHandler(GotUnknownNode); Each event requires its own event handler class and passes a distinct data structure to the client code. All the event data structures share the properties listed in Table 11-4.

In addition, the XmlElementEventArgs, XmlAttributeEventArgs, and XmlNodeEventArgs classes add some extra and more specific properties. Figure 11-1 shows a sample application that lets you enter some XML code.

At a minimum, test should be responsible for monitoring the aggregated crash data and measuring the progress against fix goals. A wealth of additional information can be mined when you know all the different ways customers have found to crash an application. It is vital to fix the issues causing the most customer pain, but big improvements come from investigating the root cause of the issues customers are experiencing most often. Often, understanding how an error was created or how code analysis tools, testing, or another process missed detection of the bug can lead to implementation of a solution that prevents similar types of issues from ever occurring again. Fixing the bug alone is great for the customer, but being able to prevent a class of bugs from ever seeing the light of day is a fantastic opportunity.

public string FirstName; public string Position; } Any exceptions are traced in the bottom pane of the window As shown in Figure 11-1, the ID attribute and the Title node have nothing to do with the target schema By default, the deserializer ignores unknown nodes The XmlElementEventArgs class has an extra property named Element whose type is XmlElement Likewise, XmlAttributeEventArgs features an extra Attr property that is an instance of the XmlAttribute type The XmlNodeEvent-Args class also includes a group of additional properties that look like a subset of the XmlNode class properties Importing Unmatched Data The most compelling reason to use deserialization events is that they enable you to attempt to fix incoming data that doesn't perfectly match your target schema For example, our target class contains a Position member, so the deserializer expects to find a <Position>element in the source code.
