XML Reserved Characters

  • Статья

In XML, some characters are reserved for internal use and you must replace them by entity references when they are used in data.

Entity References

The following table shows the characters that must be replaced by their entity references in all application definition files (ADFs) and instance configuration files (ICFs).

    INSERT INTO FlightNotifications(SubscriberId, DeviceName, 
        SubscriberLocale, Carrier, LeavingFrom, GoingTo, 
        Price, Conditions)
    SELECT S.SubscriberId, S.DeviceName, S.SubscriberLocale, 
        E.Carrier, E.LeavingFrom, E.GoingTo, E.Price, 
        E.Conditions
    FROM FlightEvents E, FlightSubscriptions S
    WHERE E.LeavingFrom = S.LeavingFrom
    AND E.GoingTo = S.GoingTo
    AND ( (E.Carrier = S.Airline) OR (S.Airline = '*') )
    AND E.Price &lt; S.Price
</Action>
