             Summary: Marshaller:sendAttributeToWriter broken by Attr without namespace
                 Key: SANTUARIO-457
                 URL: https://issues.apache.org/jira/browse/SANTUARIO-457
             Project: Santuario
          Issue Type: Bug
    Affects Versions: Java 2.0.6
            Reporter: Alessio Soldano
            Assignee: Colm O hEigeartaigh


Marshaller:sendAttributeToWriter assumes that the Attr instance that's passed in has valid (not null) namespace, it uses DOM Level 2 methods to get namespace, localname and prefix. In case of a DOM Level 1 attribute (as org.apache.xerces.dom.AttrImpl), those methods all return null, which later causes a NPE when the XmlWriterToTree tries to write the attribute:

I think there should be a check for the actual availability of namespace; if it's not available, Santuario should use Attr:getName() instead of Node:getLocalName().
