Interface for an XML filter.
An XML filter is like an XML reader, except that it obtains its events from another XML reader rather than a primary source like an XML document or database. Filters can modify a stream of events as they pass on to the final application.

virtual XMLReader * getParent() const = 0;
Set the parent reader.
This method allows the application to link the filter to a parent reader (which may be another filter). The argument may not be null.
virtual void setParent(
XMLReader * pParent
) = 0;
Get the parent reader.
This method allows the application to query the parent reader (which may be another filter). It is generally a bad idea to perform any operations on the parent reader directly: they should all pass through this filter.
