先使用度量的聚合列表中的第一个聚合函数(在这个示例中是SUM)对表达式模板进行聚合，产生一个查询。
A FLWOR expression is much like a SELECT-FROM-WHERE expression in SQL: it is used to iterate through a list of items and to optionally return something that is computed from each item.
FLWOR表达式非常像SQL中的SELECT - FROM - WHERE表达式——它用于对由多项组成的一个列表进行迭代，并且可以选择返回通过在每一项上进行计算得到的值。
This clause is used to assign a value (possibly containing a list of several items) to a variable that can be used in other clauses of the FLWOR expression.
该子句用于将一个值(可能包含一个由多项组成的列表)赋给一个变量，这个变量可以在FL WOR表达式的其他子句中使用。
A list expression is any expression that returns a list of resources or a result that can be converted to a list of resources.

并且您可以使用字母集合(就像您可能在正则表达式中使用的那样)，例如，用于列出具有“c”或“o”扩展名的文件，如清单2所示。
For example, if the expression doesn't use the last function then it is not necessary to do look-ahead processing to determine how many elements there are in the context list.
例如，如果表达式不使用last函数，那么就不必执行先行处理来确定上下文列表中有多少元素。
Finally, the last expression applies the lambda expression to the list containing (101 102).
最终，最后一个表达式对包含 (101 102)的列表应用这个lambda 表达式。
