Re: Re[2]: Entity parsing - continued

[Peter R. <php...@pe...>]

just been reading up a bit further on expat, and it seems if you do not set a 
character data handler but let it be handled by the default handler, this has 
the effect of not parsing/expanding internal entities. Just tested this in 
php briefly, and it's true. Might this be the way forward (of course it's 
perfectly possible it might screw something else up!)? Only set a character 
data handler if you want the entities parsed?

It also seems expat can after all handle external DTDs and PEs, but you have 
to define this when you compile it. I see the latest versions of PHP now have 
handlers for namespaces, so perhaps they will get around to PEs eventually.
