如何摆脱class属性并使用xstream执行自己的转换?

首先,我读过 link text 它不能解决我的问题。

我正在使用带有别名的XStream。

条件是一个具有多个不同实现的接口。我想删除class属性。我知道xstream在实现类不明确时使用class属性,并且我最多可以为其中一个实现类设置别名。我想一起删除class属性,并使用type属性加上其他子元素来确定实现类。这有可能吗?

以下是我当前使用的XML:

<NextDestinations>
  <Connector>
    <DestinationId>2</DestinationId>
  </Connector>
  <Connector>
    <DestinationId>3</DestinationId>
    <condition class="com.orchestral.rhapsody.configuration.filter.condition.JavaScriptCondition" type="JAVASCRIPT">
      ...
    </condition>
  </Connector>
  <Connector>
    <DestinationId>4</DestinationId>
    <condition class="com.orchestral.rhapsody.configuration.filter.condition.MessageTypeCondition">
      <type>CONDITIONAL</type>
      ...
    </condition>
  </Connector>
  <Connector>
    <DestinationId>5</DestinationId>
    <condition class="com.orchestral.rhapsody.configuration.filter.condition.MessageTypeCondition">
      <type>CONDITIONAL</type>
      ...
    </condition>
  </Connector>
  <Connector>
    <DestinationId>6</DestinationId>
    <condition class="com.orchestral.rhapsody.configuration.filter.condition.PropertyCondition">
      <type>CONDITIONAL</type>
      ...
    </condition>
  </Connector>
  <Connector>
    <DestinationId>7</DestinationId>
    <condition class="com.orchestral.rhapsody.configuration.filter.condition.FieldCondition">
      <type>CONDITIONAL</type>
      ...
    </condition>
  </Connector>
  <noMatchDestination>8</noMatchDestination>
  <errorDestination>9</errorDestination>
</NextDestinations>

这是我想要的XML:

<NextDestinations>
  <Connector>
    <DestinationId>1</DestinationId>
  </Connector>
  <Connector>
    <DestinationId>2</DestinationId>
    <condition type="JAVASCRIPT">
      ...
    </condition>
  </Connector>
  <Connector>
    <DestinationId>3</DestinationId>
    <condition type="CONDITIONAL">
      ...
    </condition>
  </Connector>
  <Connector>
    <DestinationId>4</DestinationId>
    <condition type="CONDITIONAL"
      ...
    </condition>
  </Connector>
  <Connector>
    <DestinationId>5</DestinationId>
    <condition type="CONDITIONAL">
      ...
    </condition>
  </Connector>
  <Connector>
    <DestinationId>6</DestinationId>
    <condition type="CONDITIONAL">
      ...
    </condition>
  </Connector>
  <Connector>
    <DestinationId>7</DestinationId>
    <condition type="CONDITIONAL"
      ...
    </condition>
  </Connector>
  <noMatchDestination>8</noMatchDestination>
  <errorDestination>9</errorDestination>
</NextDestinations>
