例如,在过滤器表达式 $x[count(.|$y)=count($y)]中(它是XSLT 1.0 中执行一组逻辑乘操作的唯一简便方法)中,Saxon 只对 count($y) 求值一次。
For example in the filter expression $x[count(.|$y)=count($y)] (which is the only convenient way in XSLT 1.0 of doing a set intersection operation), Saxon will evaluate count($y) only once.
在算逻部件中,寄存器存放要进行加、减、乘、除及比较的数据项,而其它寄存器则存放算术及逻辑操作的结果。
In the ALU, registers strore data items that are added, substracted, multiplied, divided and compared. Other registers strore the result of arithmetic and logic operations.
