dom-node
xml-string		 S_OK — An empty value is returned.

Remarks

It is possible for a reader to recognize a property name but not be able to return its state. Although a core set of properties is defined, a reader is not required to recognize specific property names. Some property values may be available only in a specific context, such as before, during, or after a parse.

The ISAXXMLReader interface recognizes the following properties:

  • "http://xml.org/sax/properties/lexical-handler"

    This is an optional extension handler for lexical events like comments with the following settings:

    • Data type

      ISAXXMLLexicalHandler.

    • Access

      Read/write.

  • "http://xml.org/sax/properties/declaration-handler"

    This is an optional extension handler for declaration events with the following settings:

    • Data type

      ISAXXMLDeclHandler.

    • Access

      Read/write.

  • "xmldecl-encoding"

    Encoding declared in the XML header of the currently parsed document. This data is unavailable until the reader parses the XML header. This property has the following settings:

    • Data type

      BSTR*.

    • Default

      Empty if there is no XML declaration or if a property is not found.

    • Access

      Read for parsing; none when non-parsing.

  • "xmldecl-version"

    Version declared in the XML header of currently parsed document. This data is unavailable until the reader parses the XML header. This property has the following settings:

    • Data type

      BSTR*.

    • Default

      Empty if there is no XML declaration.

    • Access

      Read for parsing; none when non-parsing.

  • "xmldecl-standalone"

    Declared in the XML header of currently parsed document. This data is unavailable until the reader parses the XML header. This property has the following settings:

    • Data type

      BSTR* ("yes" or "no").

    • Default

      Empty if there is no XML declaration or if a property was not found.

    • Access

      Read for parsing; none when non-parsing.

The "xmldecl-encoding", "xmldecl-version", and "xmldecl-standalone" properties provide information about the presence and content of the XML header. However, XML header information was designed for low-level reader and parser use, not for applications.

Requirements

OS Versions: Windows CE .NET 4.0 and later.
Header: Msxml2.h, Msxml2.idl.
Link Library: Uuid.lib.
