problem with null namespace for local attributes in importNode (DOM level 2) 2003-01-23 - By Aleksandar Milanovic
Hi,
Eventually I found an error in the method
AttrNSImpl.setName(String namespaceURI, String qname)
However, I am not sure if this has been fixed since 2.2.1. The error is that
the namespace string was interned, but then the original namespace string
used instead of the interned ones. This led to erros in subsequent string
comparisons using ==.
I've never submitted a bug fix before. Since this is really a small one, is
there somebody out there who'd be willing to do this for me? I'd provide the
fixed source file.
thx
Alex
