position函数计数节点—元素和文本节点—即使文本只是空白。

The position function counts nodes-both elements and text nodes-even if the text is just white space.

与计数函数类似，当在一个规则中使用多个具有分组关键字的聚合，对分组与计数操作必须进行级联，如图14所示。

Like the counting function, when several aggregations with grouping keys are used in a rule, the group and count operations must be cascaded as shown in figure 14.

不过，当您使用某个采用引用计数的数据结构时，您必须记得运行引用计数函数。

However, you must remember to run the reference counting functions whenever you are using a reference-counted data structure.

It didn't really crash, it found an assert statement. So if you look at the bottom of the function, you'll see that, in fact, I checked for that.

其实程序并没崩溃,它只是碰到一个断言语句然后停了下来,如果你看看函数的顶部，你会看到，实际上我断定计数器。
