Manipulation of feed type and the Repeating element of the Source operators' advanced setting.
同样，将扇入设置为在处理完所有的重复元素时完成(请参见图9)。
Equally, the Fan in is set to complete when all of the repeating elements have been handled (see Figure 9).
在本例中，重复的元素中包含重复元素，所以聚合是双重的和嵌套的。
In this case, you have repeating elements within repeating elements, so the aggregation is two-fold and nested.
在前一节中指出，在节点序列(比如重复元素)上只能应用删除操作。
In the previous section, you learned that only the delete operation can be applied to a sequence of nodes, such as repeating elements.
通过使用默认的相等比较器对值进行比较返回序列中的非重复元素。
Returns distinct elements from a sequence by using the default equality comparer to compare values.
同样，将扇入设置为在处理了所有的重复元素时完成(请参见图37)。
Equally, the Fan in is set to complete when all of the repeating elements have been handled (see Figure 37).
同样，将扇入设置为在处理了所有的重复元素时完成（请参见图33）。
Equally, the Fan In is set to complete when all of the repeating elements have been handled (see Figure 33).
当扇出在iterate模式下使用时，扇出上下文用于存储重复元素的当前项。
The Fan Out Context is used to store the current item of a repeating element when Fan Out is used in iterate mode.
如示例4的步骤1所述，使用一个XML输入stage处理响应中的重复元素。
As mentioned in step 1 of sample 4, an XML input stage is used to handle the repetition element in responses.
这将指示DataStage使用这个XML元素值作为重复元素标识符。
This instructs DataStage to use this XML element value as the repetition element identifier.
例如，如果名为order的元素有重复元素，则扇出上下文应该与清单1所示类似。
For instance, if there was a repeating element of an element called order, the Fan Out Context would look like Listing 1.
XMLInput阶段将遍历重复元素，并为每个重复的元素生成一个输出记录。
The XML Input stage will loop through the repetition element and produce an output record for each occurrence of that element.
因此，外部聚合将迭代所有的重复元素，而内部聚合将构建从两个服务调用聚合的响应。
So the outer aggregation iterates through all of the repeating elements, while the inner aggregation builds a response aggregated from the two service invocations.
为了实现映射，右键单击输出树中的重复元素并在菜单中选择addIndex，见图1。
To produce the mapping, right-click the repeating element in the output tree and select Add Index from the menu as shown in Figure 1.
XMLInput阶段使用Key列标识重复元素，这决定如何生成 XML数据。
The XML Input stage uses a Key column to identify the repetition element, which determines how the XML data is generated.
GMGP提供的复元素既能为交互绘图系统提供类似于子图形的功能，又能用于构作图形模型。
The graphic object (compound object) in GMGP can be used like the sub-picture in interactive graphics and can also be used for composing the graphic model.
使用条件的另一方法是将筛选器应用到可重复元素的列表上，如第2部分中的“筛选数组”中所述。
Another way to use conditions is to apply a filter to a list of repeatable elements.
如果选择了重复元素(repeating element)选项，则必须提供XPath表达式。
If the repeating element option is selected, then an XPath expression must be provided.
您可以为每个联系点创建一个元素，也可以使用带有一个修饰属性的单个重复元素来标识他的每个地址。
You might create an element for each one, or use a single, repeating element with a qualifying attribute to identify each of his addresses.
在上一个小节编辑XMLInput阶段时，您在步骤3和步骤9中所做的工作标识重复元素的key值。
When you edited the XML Input stage in the previous section, the work you performed in Steps 3 and 9 identified the Key value and repetition element.
嵌套的聚合：如果场景是第二种模式中描述的基本批处理模式，但是重复元素本身包含重复元素，则此模式非常有用。
Nested aggregation: This pattern is useful if the scenario is the basic batch processing pattern described in the second pattern, but the repeating elements themselves contain repeating elements.
使用消息充实的批处理：如果要处理的消息包含重复元素，并且需要单独操作每个元素才能对其增强，则此模式非常有用。
Batch processing with message enrichment: This pattern is useful if the message to be processed contains a repeating element, and each element needs to be enhanced by acting on each one separately.
