The New 4GL Objects and Handles
DOM Node Interfaces As Subtypes
Since it is necessary to be able to use some of the other specialized interfaces as well as the simplified interface, the DOM objects that have these specialized interfaces are implemented as Subtypes of the Progress object.
The Progress 4GL supports the following interfaces as Subtypes on the X-NODEREF:
The default Subtype will be ELEMENT.
Table 11–2 shows the “simplified” DOM Node interface nodeNames and nodeValues.
The Progress 4GL NAME attribute will be used to return the nodeName, while a new NODE-VALUE character attribute will return or set the node’s nodeValue.
