The XML SAX feature for Windows Embedded CE operating system (OS) provides two co-classes that implement the XML Reader interface.

SAXXMLReader

The version-independent co-class. Uses the most current implementation. (CLSID_SAXXMLReader: 079aa557-4a18-424a-8eee-e39f0a8d41b9)
SAXXMLReader30

The version-dependent co-class. Ties the application to msxml3.dll. (CLSID_SAXXMLReader30: 3124c396-fb13-4836-a6ad-1317f1713688)

Registering Handlers

An application can set and query features in the reader, register event handlers for document processing, and initiate a document parse. With this COM implementation of Simple API for XML (SAX2) in C++, the reader can use the following methods to register the corresponding handlers.

Method	Description
ISAXXMLReader::putContentHandler Method	Registers a content handler.
ISAXXMLReader::putDTDHandler Method	Registers a DTD handler.
ISAXXMLReader::putErrorHandler Method	Registers an error handler.

Controlling Reader Behavior

You can use the following methods to observe and control the behavior of the reader.

Method	Description
ISAXXMLReader::getFeature Method	Allows an application to ask the reader if it supports a feature.
ISAXXMLReader::putFeature Method	Allows an application to request that the reader turn a particular feature on or off.

Supported Features and Properties

The Microsoft COM/C++ implementation of SAX2 supports the following features, for example, a property whose value is Boolean:

"http://xml.org/sax/features/namespaces"
"http://xml.org/sax/features/namespace-prefixes"
"http://xml.org/sax/features/external-general-entitities"
"http://xml.org/sax/features/external-parameter-entities"
"normalize-line-breaks"
"server-http-request"

The reader also provides the ISAXXMLReader::getProperty Methodand ISAXXMLReader::putProperty Methodmethods for getting and putting these properties.

"http://xml.org/sax/properties/lexical-handler"
"http://xml.org/sax/properties/declaration-handler"
"xmldecl-encoding"
"xmldecl-version"
"xmldecl-standalone"

Method	Description
ISAXXMLReader::getBaseURL Method	Returns the base URL for the document.
ISAXXMLReader::putBaseURL Method	Sets the base URL for the document.
ISAXXMLReader::getContentHandler Method	Returns the current content handler.
ISAXXMLReader::putContentHandler Method	Allows an application to register a content handler.
ISAXXMLReader::getDTDHandler Method	Returns the current DTD handler.
ISAXXMLReader::putDTDHandler Method	Allows an application to register a DTD handler.
ISAXXMLReader::getEntityResolver Method	Returns the current entity resolver. At this time, the EntityResolverproperty cannot be set for this implementation of SAX2 (Simple API for XML).
ISAXXMLReader::putEntityResolver Method	Allows an application to register an entity resolver. At this time, the EntityResolverproperty cannot be set for this implementation of SAX2 (Simple API for XML).
ISAXXMLReader::getErrorHandler Method	Returns the current error handler.
ISAXXMLReader::putErrorHandler Method	Allows an application to register an error handler.
ISAXXMLReader::getFeature Method	Returns the Boolean value of a feature.
ISAXXMLReader::putFeature Method	Sets the value of a feature.
ISAXXMLReader::getProperty Method	Returns the value of a property. (Currently no properties are supported.)
ISAXXMLReader::putProperty Method	Sets the value of a property.
ISAXXMLReader::getSecureBaseURL Method	Returns the secure base URL for the document.
ISAXXMLReader::putSecureBaseURL Method	Sets the secure base URL for the document.
ISAXXMLReader::parse Method	Parses an XML document.
ISAXXMLReader::parseURL Method	Parses an XML document from a system identifier.
