To do this we create an information context list from the XML fragment.

为此，我们从这个xml片段创建一个信息上下文列表。

youdao

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。
