允许用户使用定制排序、过滤和查询表达式解析扩展搜索行为。
Allows users to extend the searching behavior using custom sorting, filtering, and query expression parsing.
在XPath表达式中排序。
use - when测试还可以帮助选择定序法，只要包含的表达式告诉您可用何种排序法。
A use-when test can also help you choose collations, as long as it includes an expression that will tell you which collations are available.
最后，也是最重要的，该表达式将忽略对for子句返回的节点集所执行的筛选或排序操作。
Finally, and most importantly, this will ignore any filtering or ordering you perform on the node set returned by the for clause.
将表达式中的列名改为关系数据库中希望根据已选的特定列进行排序的列的名称。
Change the column name in the expression to be the name of the column from the relational database you want to sort on for the particular column you selected.
这使得在XPath表达式中的任何级别上对任意节点集合进行排序成为可能。
This makes it possible to sort any arbitrary set of nodes at any level within an XPath expression.
然后，您可以在XPath表达式中使用这些规范来对数据进行排序。
You can then use these specifications within XPath expressions to sort data.
要添加对输出的排序，只需将一个代码行添加到rss -summary函数中的for、let、where、order by和return (FLOWR)表达式中，对输出进行排序即可，如清单7中所示。
To add sorting to the output, you just need to add a line to the for, let, where, order by, and return (FLOWR) expression within the rss-summary function to order the output, as in Listing 7.
这个表达式意味着，如果“OrderBy”参数的值是“1”，就用第一列“Retailertypecode”的内容填充这个排序列。
This essentially means that if the "OrderBy" parameter has a value of "1", this sorting column will be populated with the content of the first column, "Retailer type code".
在“网格”窗格中，定位到包含用作排序依据的首个数据列或表达式，然后在“排序类型”网格列中，选择“升序”或者“降序”。
In the Grid pane, locate the row containing the first data column or expression to sort by, and then in the Sort Type grid column, choose Ascending or Descending.
终结符号处理过程中，深入地研究了字符串匹配算法和正则表达式匹配算法，并实现了二叉排序树字符串匹配算法。
First, classic string matching algorithms and regular expression matching algorithms are studied; second a binary sort tree string matching algorithm is proposed and realized.
