QXmlEntityResolver(3qt)QXmlEntityResolver(3qt)NAMEQXmlEntityResolver - Interface to resolve external entities contained
in XML data
SYNOPSIS
All the functions in this class are reentrant when Qt is built with
thread support.</p>
#include <qxml.h>
Inherited by QXmlDefaultHandler.
Public Members
virtual bool resolveEntity ( const QString & publicId, const QString &
systemId, QXmlInputSource *& ret ) = 0
virtual QString errorString () = 0
DESCRIPTION
The QXmlEntityResolver class provides an interface to resolve external
entities contained in XML data.
If an application needs to implement customized handling for external
entities, it must implement this interface, i.e. resolveEntity(), and
register it with QXmlReader::setEntityResolver().
See also the Introduction to SAX2.
See also QXmlDTDHandler, QXmlDeclHandler, QXmlContentHandler,
QXmlErrorHandler, QXmlLexicalHandler, and XML.
MEMBER FUNCTION DOCUMENTATIONQString QXmlEntityResolver::errorString () [pure virtual]
The reader calls this function to get an error string if any of the
handler functions returns FALSE.
bool QXmlEntityResolver::resolveEntity ( const QString & publicId, const
QString & systemId, QXmlInputSource *& ret ) [pure virtual]
The reader calls this function before it opens any external entity,
except the top-level document entity. The application may request the
reader to resolve the entity itself (ret is 0) or to use an entirely
different input source (ret points to the input source).
The reader deletes the input source ret when it no longer needs it, so
you should allocate it on the heap with new.
The argument publicId is the public identifier of the external entity,
systemId is the system identifier of the external entity and ret is the
return value of this function. If ret is 0 the reader should resolve
the entity itself, if it is non-zero it must point to an input source
which the reader uses instead.
If this function returns FALSE the reader stops parsing and reports an
error. The reader uses the function errorString() to get the error
message.
