Hi,
IIRC Axiom does not support the feature of creating an OMNode if it does not
exist when queried using an XPath expression. Is this DOMUtil class that you
have mention, the main class which is used to handle XPath in DOM? I mean is
it the similar DOM version of AXIOMXPath class?
Modifying the existing selectSingleNode() method may introduce certain
backward compatibility issues. So it would be better to come up with an
overloaded method like selectSingleNode(OMElement root, boolean create).
That way the exisiting method will equal to selectSingleNode(root, false).
Thanks,
Saliya
