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.
The XMLFilterImpl helper class provides a convenient base for creating SAX2 filters, by passing on all IEntityResolver, IBufferedDTDHandler, IBufferedContentHandler and IErrorHandler events automatically.
procedure setParent(const parent : IBufferedXMLReader);
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.
function getParent() : IBufferedXMLReader;
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.
