CExtensionPackageContext

CTopLevelExtensionContext

CTopLevelExtensionContext();

Constructs the top-level extension context.

~CTopLevelExtensionContext

virtual ~CTopLevelExtensionContext();

Destroys the top-level extension context.

EnterContext

virtual void EnterContext(bool bTopLevel) = 0;

Called by the XSLT engine on entering the new context.

The context is entered when the processing (in particular, instantiation) of the new stylesheet element is started.

Application developers do not use this function.

Parameters:

bTopLevel - indicates that the context entered is associated with the top-level stylesheet element (for example, the template)

ExitContext

virtual void ExitContext() = 0;

Called by the XSLT engine on exit from the context.

The exit from the context occurs when processing (for example, instantiation) of the stylesheet element is finished.

Application developers do not use this function.

FindExtensionPackageContext

virtual XExtensionPackageContext FindExtensionPackageContext(
    const CString &strNamespaceUri) = 0;

Looks up the extension package context associated with the given namespace URI.

Parameters:

strNamespaceUri - the namespace URI to look up

Returns:

the extension package context associated with the given namespace URI in this top-level extension context, or NULL if the extension package is not found
