[jdom-interest] Re: xsi:nil

[Scott Ellis]

Hey, thanks a lot! It works and I can continue (thank goodness).  Here is
the code I use:

Attribute attr = new Attribute( "nil", "true" );
attr.setNamespace( Namespace.getNamespace( "xsi",
"http://www.w3.org/2001/XMLSchema-instance" ) );
child.setAttribute( attr );

Thanks again!

Scott
