Is exactly what I'm trying to say(my lack of English grammar skills
doesn't help). :)

Is possible if TXmlReader keeps track of the it's current path. Let's say:
TMyXmlReader = class(TXmlTextReader)
private
FPath: TStrings; //or another dedicated new CLass to keep a
list of nodes.
public
Register(XPathExpression: string; MethodToCall);
end;
At each step of processing, FPath is updated and is compared to XPathExpression.
