The requirement is to find the duplicate element(BaseName) in XML and marked the parent element(Account) with isDuplicate attribute. The XSL is working correctly when the input XML RootElement has no namespaces. When the root element has namespace then I get empty object. I am not sure why the namespace is causing XSL to generate empty output. Any help to get the right output would be greatly appreciated.`
