DevOps, CI/CD and Automation

Hi ,
I am trying to use the document.getElementById() method to obtain a value from the XML. I have done the following:
1. Defined the attribute as type ID [ <xsd:attribute name="id" type="xsd:ID" use="required" /> ]

2. Provided the schema location in the XML.

However in the code when I do a getElementById, I get a null.

Code snippet that I use is:

File capabilityfile = new Fiile("capabilities.xml");
URL capfile = capabilityfile.toURL();
oracle.xml.parser.v2.DOMParser parser = new oracle.xml.parser.v2.DOMParser();
parser.setValidationMode( XMLParser.SCHEMA_VALIDATION );
parser.parse( capfile );
Document capFileRoot = parser.getDocument();
System.out.println(capFileRoot.getElementById( "ASYNC"));

Am I missing something here?

Thanks,
Mridhula
