Handling errors: DOMError, DOMObject, DOMLocator

[Frans Englich]

Hello,

Many XML applications needs to do error reporting with the physical file as 
background. E.g, they reach a certain point and need to report something that 
was wrong on a certain line.

DOMError and DOMLocator exists, and after having read the DOM 3 core spec, I 
still don't understand how I should use them. When I've found an error, how 
do I create a DOMError, and how do I "pass it on" to the host code(somehow 
the DOMImplementation since it should test it against DOMErrorHandler)?

I'm also wondering about the DOMObject member of DOMError, which currently is 
commented out. AFAICT, the DOMObject is supposed to be a base class which 
data specific to the DOMError object is cast to. How is this supposed to be 
solved? Should all classes inherit from DOMObject? :)

In short: how do one do error reporting?


Cheers,
