1/6/2010

This method returns the value of a property. The property name is any qualified Uniform Resource Identifier (URI).

HRESULT getProperty(
  const wchar_t* pwchName,
  VARIANT* pvarValue
);

• pwchName
  [in] Pointer to the property's name (zero-terminated Unicode string).

• pvarValue
  [out, retval] Pointer to the corresponding data type for the property.

Return Value

The following table lists the return values for the getProperty method.

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.
