XOM API for Processing XML with Java

["Michael Kay" <mike AT saxonica.com>]

There are several versions of AElfred around, the code has forked at least
once. You need to be clear which you are using. (And probably, find a list
that's more appropriate than this one...)

> Hi,
> 
> I'm using a default XML reader to set an entity resolver for 
> a DTD. First, I
> wrote a library to read an XML file. I tested it and it worked fine.
> It turned out it was using Crimson parser as a default. Then 
> I used the same
> library in my application. It threw an exception saying that
> it couldn't resolve dtd. I checked in the debugger and it 
> turned out that
> picked up an Aelfred parser somewhere on the classpath. I inserted
> a print statement to check if it was calling it at all and it wasn't.
> However, when I set a Xerces parser explicitly in my code 
> everything worked
> fine both in the library and in the application. It leads me 
> to believe that
> Aelfred parser is not adding the DTD handler properly.
