Справка с циклическим справочником по самоссылке XSD

/ 19 августа 2011

Я пытаюсь создать класс C # из файла XSD.Короче говоря, я получаю ошибку циклической ссылки при попытке запустить инструмент XSD.exe:

Группа 'setFilterCondition' из targetNamespace = 'http://developer.cognos.com /schemas/report/7.0/' недействительнаопределение: ссылка на круговую группу.

Я вытащил определение группы, и у меня есть следующий XSD для него: 

<xs:group name="setFilterCondition">
        <xs:annotation>
            <xs:documentation>Represents a simple or compound set filter condition</xs:documentation>
        </xs:annotation>
        <xs:choice>
            <xs:element name="setFilterAnd">
                <xs:annotation>

Я вижу, что у него есть подгруппы, которые имеюттот же тип родителя.Почему это вызывает круговую ссылку?Как я могу отредактировать этот XSD, чтобы не вызывать ошибку?

То же самое спросили на SO некоторое время назад ... это пост , с некоторыми ответами.

Предлагаемое мной решение должно быть проще, особенно в вашем случае, когда вы можете редактировать XSD, а сама группа полностью описывает содержание элемента, в котором он используется.

Хитрость заключается в том, чтобы затем повторно использовать и реализовать рекурсивность вашего контента не через групповые ссылки, а через сложный тип.Если вы сравните свою схему с шахтой ниже, вы заметите, как я определил и использовал сложный тип.

Надеюсь, это поможет кому-то еще ....

РеорганизованныйXSD работает с XSD.exe, класс генерирует чистый, без ошибок.
