Note: All functions in this class are reentrant.

Member Function Documentation
Destroys the entity resolver.
[pure virtual] QString QXmlEntityResolver::errorString() const
The reader calls this function to get an error string if any of the handler functions returns
[pure virtual] bool QXmlEntityResolver::resolveEntity(const QString &publicId, const QString &systemId, QXmlInputSource *&ret)
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
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.
