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 |
|---|---|
Registers a content handler. |
|
Registers a DTD handler. |
|
Registers an error handler. |
Controlling Reader Behavior
You can use the following methods to observe and control the behavior of the reader.
| Method | Description |
|---|---|
Allows an application to ask the reader if it supports a feature. |
|
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:
"https://xml.org/sax/features/namespaces""https://xml.org/sax/features/namespace-prefixes""https://xml.org/sax/features/external-general-entitities""https://xml.org/sax/features/external-parameter-entities""normalize-line-breaks""server-http-request"
The reader also provides the ISAXXMLReader::getProperty Method and ISAXXMLReader::putProperty Method methods for getting and putting these properties.
"https://xml.org/sax/properties/lexical-handler""https://xml.org/sax/properties/declaration-handler""xmldecl-encoding""xmldecl-version""xmldecl-standalone"
