Description
GetExtendedValue is an
Extended function used to get
the value for a DOM node at the specified path as an Extended data type.
GetExtendedValue is similar to the
GetValue method;
in fact it calls GetValue to retrieve the value for the DOM node in
APath. It calls
StrToExtended to convert the node value
to the Extended data type used as the return value.
Use ADefault to specify the default value used in the method when
the DOM node does not contain any content (or value).
