What’s New in System.Data: What’s New in System.Data: DataSet EnhancementsDataSet Enhancements

Increasingly, XML is used in the middle tier of applications can be easily serialized works well over all kinds of networks provides de-coupling between tiers can be cached in a DataSet or as an XML

Design Goals for System.Xml v2.0

XML in the Middle Tier

Reading, Writing and Validating XML

Enhancements to the XPathDocument

Reading, Writing and ValidationReading, Writing and Validation

Topics are: Static Create Methods

XmlReaderSettings and XmlWriterSettings

Reading and Writing Typed XML

XmlSchemaSet and Schema Inference

Validation with an XmlReader

Resolving Entities

Static Create and SettingsStatic Create and Settings Why ?

Provides a single location to create XmlReaders and XmlWriters avoids the proliferation of specifically typed

readers/writers

Provides some internal optimizations

Allows pipelining of XmlReader instances

Static Create and SettingsStatic Create and Settings Create an XmlReader or XmlWriter with

predefined settings:XmlReaderSettings settings

= new XmlReaderSettings();

settings.Schemas.Add("books.xsd");

settings.XsdValidate = true;

XmlReader reader =

XmlReader.Create("books.xml",

settings);

while(reader.Read()) { }

Reading & Writing Typed XMLReading & Writing Typed XML For XmlReader, XmlWriter, XPathNavigator:

new methods that return CLR types, e.g.:Double p = reader.ReadValueAsDouble();

For XmlWriter: new method that accepts CLR types, e.g.:

DateTime date = new DateTime(2004,5,24);

writer.WriteStartAttribute("pubdate");

writer.WriteValue(d);

writer.WriteEndAttribute();

XmlSchemaSet and InferenceXmlSchemaSet and Inference New XmlSchemaSet class

stores schemas and correctly handles multiple references to inherited schemas

replaces XmlSchemaCollection System.Xml.Schema.Inference class

Can infer schema from an XML documentXmlSchemaSet xs = InferSchema(XmlReader[,

XmlSchemaSet

InferenceOption enumeration defines how data types and schema occurrences found in the document are interpreted values are: Relaxed or Restricted

Validation with an XmlReaderValidation with an XmlReader XmlReader can be used for validation

XmlValidatingReader is now obsolete create XmlReader that validates using static

Create technique specify schema(s) in the XmlReaderSettings:

settings.Schemas.Add("books.xsd");

Turn on validation:settings.XsdValidate = true;

Then use the reader

Resolving EntitiesResolving Entities XmlReader created with static Create

method can expand entities set the EntityHandling property:

ExpandCharEntities (the default): expands only character entities

ExpandEntities: expands all entities for example, <elem>&#65; &num;</elem>

ExpandCharEntities gives: <elem>A &num;</elem>

ExpandEntities gives: <elem>A 123</elem>

Enhancements to the XPathDocument

XML Document StoresXML Document Stores New Features of the XPathDocument

support for document editing with an XmlWriter and XPathEditableNavigator

full CLR data type support

new change tracking and edit events

new support for validation

richer support for XSLT

new serialization features

Will be in XmlDocument for Beta 2

Editing in an XPathDocumentEditing in an XPathDocument Editing contents of an XPathDocument:

CreateWriter( ) XmlWriter CreateEditor( ) XPathEditableNavigator

New CLR Type Support properties for the navigator classes:

ValueAsDouble ValueAsDateTime ValueAsList etc. methods for writer and editable navigator:

WriteValue(typedValue), SetValue(typedValue)

New Select methods for XPathNavigator SelectSingleNode("XPath" [, nsResolver ]) Select("XPath", nsResolver) Evaluate("XPath", nsResolver)

Change TrackingChange Tracking Turn on change tracking:

set EnableChangeTracking = true See if there are any changes:

call the HasChanges( ) method Manage change tracking state:

AcceptChanges( ) and RejectChanges( ) methods

React to Change Events: ItemDeleting, ItemDeleted, ItemUpdating,

ItemUpdated, ItemInserting, ItemInserted, ChangeRejected.

Validation and XSLT SupportValidation and XSLT Support Validate XPathDocument with Navigator

Schemas property XmlSchemaSet CheckValidity(schema-set, event-handler) raises validation event for each error found

"Validate directly" coming in Beta 2 no need for an XPathNavigator

Use XPathNavigator as the source for XSLT transformations using XsltCommand class

Serializing an XPathDocumentSerializing an XPathDocument Load and save XML with an

XPathDocument ReadXml, WriteXml, Save

... or through an XPathNavigator or an XPathEditableNavigator ReadSubtree( ), WriteSubtree(XmlWriter)

Specify the Encoding for an XPathDocument or XmlWriterSettings Encoding property System.Text.Encoding

instance

The IXmlSerializable Interface The IXmlSerializable Interface Originally "internal" and designed for use

by the ADO.NET DataSet

Now available for custom serialization ReadXml takes an XmlReader

WriteXml takes an XmlWriter

GetSchema is deprecated

Allows you to take full control of the wire format and schema of the data

XML in Visual Studio 2005XML in Visual Studio 2005

Great new support for XML in VS 2005 New XML Editor

supports XML 1.0 conformance checking

allows the XML to be validated against a schema as it is being edited

Intellisense and element completion

XSLT debugging Single-step, run, view input/output
