So the return value (sort of a misnomer, but still a useful way to think about things) for an attribute selector is a value; for an element, it's a node set (containing a single node).
因此对于属性选择器，返回值（虽然不确切但是很有用）是一个值，对于一个元素则是一个节点集（包含一个节点）。

After a node is listed on the return grid, you can drill down into the query to add predicates and sorting preferences.
当一个节点在返回网格中被列出来时，就可以钻取(drilldown)到查询中，添加谓词和排序方式。
If you return false from the visit method, the children of this node won't be visited.
如果visit方法返回false，那么该节点的子接点将不会被访问。
An alternative is to use XPath constructs to create filtered subsets of the XML node tree and return them to the caller.
另外也可以使用XPath构造创建xml节点树的过滤子集并将其返回给调用方。
You can use the RegistryLookup node to return an arbitrary document from Registry and Repository, which could contain addressing details for any external service.
可以使用RegistryLookup节点从 Registry and Repository返回任意文档，其中可能包含任何外部服务的寻址细节。
However, the XPath functions name and local-name return the prefix when applied to a namespace node.
不过，xpath函数name和local - name在应用于名称空间节点时会返回前缀。
The SOAPInput node can return a SOAP fault to the client to indicate that a timeout has occurred.
SOAPInput节点可以向客户端返回SOAP错误以指示发生了超时。
If the XPath expression does return more than one node and you've specified XPathConstants.NODE, then evaluate returns the first node in document order.
如果XPath表达式返回了多个节点并且指定了XPathConstants . NODE，则evaluate按照文档顺序返回第一个节点。
For example, the next two queries may return the same result, but only if all "price" elements encountered during the query execution have a single text node and no other child nodes.
例如，下面两个查询可能返回相同的结果，但条件是仅当查询执行过程中所遇到的全部“price”元素都拥有单个文本节点且没有其他子节点。
You use it when you know the XPath expression will only return a single node or you don't want more than one node.
只有知道XPath表达式只返回一个节点或者只需要一个节点时才使用它。
Even if the Oracle nodes come back up, the Oracle DTP service will not return to the freshly restarted rac node.
即使Oracle节点恢复，OracleDTP服务也不会返回到刚刚重启的rac节点。
SimpleXML's children() method is used in conjunction with the g: namespace to return this node collection as a SimpleXMLElement object named $attrs.
SimpleXML的children()方法与g:名称空间一起用于，将该节点集合作为一个名为 $attrs 的SimpleXMLElement对象返回。
The XML functions extractvalue() and extractxmlclobvalue() return the value of the XML node.
XML函数extractvalue()和extractxmlclobvalue()返回 XML节点的值。
If a SOAP processing error occurs at the SOAPInput node, it can return a SOAP fault either directly to the sender or to a different endpoint if directed to do so by WS-Addressing.
如果在SOAPInput节点上发生SOAP处理错误，它可以直接向发送者或者向某个不同的端点(如果WS - Addressing指示这样做的话)返回SOAP错误。
Return: Using a return clause lets you operate on a node set, but then return (in results) something other than that node set.
return：使用return子句允许您操作操作节点集，随后返回除该节点集以外的结果。
It's also necessary to specify the return type. Here I ask for a node-set back.
还必须指定返回类型。
Try to design your extension functions so that they use only doubles, strings, booleans, and node-sets as both arguments and return values.
尽量尝试将您的扩展函数设计为仅使用双精度、字符串、布尔和节点集作为实参和返回值的类型。
These subproblems are then distributed to worker nodes, which solve the problem and return the results to the master node.
然后将这些子问题发布给工作节点，由它处理后再将结果返回给主节点。
It takes at least two polling cycles to retrieve a job and then return results, and it could take additional cycles depending on how long the job actually takes to process on the node.
检索作业和返回结果至少要耗费两个轮询周期，并且根据节点处理作业实际花费的时间，可能会耗费更多周期。
Finally, the return clause returns the new node representing the scheduled termination date so that DB2 will update data in the DOCUMENT column with the modified data.
最后，return子句返回代表预定终止日期的新节点，所以DB 2将用修改后的数据更新document列中的数据。
For each of these nodes, it computes the expression in the return clause, which here is a mix of markup (the tags) and code (extracting the contents of the element of each node).
对于选出的每个节点，将在return子句中计算表达式，在这里是标记(标签)与代码(提取出每个节点的元素的内容)的混合。
The contents are extracted with the data() function in the return clause; otherwise, I'd get more than just the text in the node, I'd get all the markup, too.
内容是用return子句中的data()函数提取的；否则，不仅仅会得到节点中的文本，还会得到所有的标记。
