Based on the extensions mentioned I assume this is under PHP 5.x and 
libxml is being used for the xml extension. It was designed for 
compatibility with the one under PHP 4 that used expat so behavior in 5 
was based on behavior from 4. For example, expanding entity refs 
requires that no default handler is defined. In the event its an 
internal pre-defined entity, they only are not expanded when no 
character data handler is present.

So to answer your initial question, no, there is not a way to currently 
do this while also keeping compatibility between libxml2 and expat.
For this type of control you might want to look at xmlreader (though 
uses its own constants to control behavior and is not event based).
