WG: Problem with events

[Alexander Weinmann <Al...@abaxx.de>]

Hello Xerces Developers,

The Xerces Users list would not give me any response
on this. But I absolutely want to use the dom events
to implement my personal xml editor.

So could somebody just compile the small sample 
Program below and tell me what is wrong with it ...
or simply send me to lines of sample code that does the
job ...

I simply do not know how to catch "MutationEvents",
when I manipulate attributes:
