getFeature Method

  • 아티클

 

Returns the Boolean value of a SAX reader feature.

The Boolean value indicates if a feature is enabled or disabled. For example, setting the "http://xml.org/sax/features/namespaces" feature to True enables namespace processing during parsing.

Visual Basic Usage Syntax

strFeature = oSAXXMLReader.getFeature
(strName)

Parameters

strName
The name of the current feature.

The feature name is any fully-qualified Uniform Resource Identifier (URI). The values for the namespaces and namespace-prefixes features may be available only in a specific context, such as before, during, or after a parse.

Return Values

For any currently implemented feature of the SAX reader, returns the value of the feature. If a feature is named which is not currently implemented by the SAX reader, returns a trappable error.

C/C++ Syntax

HRESULT getFeature(  
   [in] const wchar_t * pwchName,  
   [out, retval] VARIANT_BOOL * pvfValue);

Parameters

pwchName[in]
The feature name (zero-terminated Unicode string).

pvfValue[out, retval]
The value of the feature (True or False).
