Почему я получаю ошибку атрибута в своем XML-документе?

Question

Я новичок в XML и продолжайте получать следующую информацию:

Элемент 'topBilledActors' основан на простом определении типа. Атрибут «идентификаторы» не определен в пространстве имен экземпляров схемы (xsi).

Answer 1

У вас есть это в XML:

<topBilledActors ids="a0100 a0102"/> 

Но согласно вашему определению схемы topBilledActors является тип actorIDREFlist и не определяет атрибут позвоните по номеру ids.

Вы можете удалить атрибут ids в своем XML или изменить определение схемы для включения этого атрибута.
