NUM-CHILDREN attribute

Returns the number of child nodes below the node referred to by a node reference. Attributes are not counted since they are not considered children of a node.

The following example demonstrates getting all the child nodes from the XML node referenced by hNoderef using the NUM-CHILDREN attribute:

REPEAT j = 1 TO hNoderef:NUM-CHILDREN: hNoderef:GET-CHILD(hNoderefChild,j). . . . END.
