Re: [xml] setting externelEntityResolver on a per-context basis

[Lars Oppermann <Lars Oppermann Sun COM>]

Hi Daniel,

It is true, that in my case xmlCtxtReadIO is most appropriate. I 
stumbled upon this, because the difference between
_xmlParserCtxt.sax.resolveEntity and
xmlSetExternalEntityLoader() are not entirely clear to me.

When using xmlCtxtReadIO, how can I make sure that I can also control 
the IO which occurs when an external subset or external DTDs are loaded? 
 While I working with this, it seemed like external entities were only 
being resolved when I had used xmlSetExternalEntityLoader before parsing 
and that setting ctxt.sax.resolveEntity had no effect whatsoever on the 
entity resolution.

So you are absolutely correct that there is no need for me to use 
xmlCtxtReadFile. I can very well do with the ReadIO version. I'm just 
wondering how to get called for resolution of external entities embedded 
in the document that is being parsed...

Thanks,
Lars
