然后遍历响应中的元素，通过 foreach()循环检索图1 中的信息。
It then iterates over the elements in the response, processes each one using a foreach() loop and retrieves the information in Figure 1.
以上示例展示了如何使用连续扫描和索引来进行数据检索，以及如何使用嵌套循环连接方法来连接所有表。
The above example shows that sequential scan and indexes are used to do the data retrieval, and the nested-loop join method is used to join all tables.
之后，它对此响应内的全部进行迭代，用foreach循环对每一个进行处理并检索信息，如图1所示。
It then iterates over the elements in the response, processing each one using a foreach loop and retrieving the information shown in Figure 1.
接下来的一段代码是一个for 循环，当变量j被初始化为0 时，该循环首先检索第一个联系人的所有 childNodes。
The next section of code, the for loop, first retrieves all the childNodes of the first contact, when the variable j is initialized to zero.
然后遍历响应中的元素，使用foreach循环处理每个元素并检索如图1所示的信息。
It then iterates over the elements in the response, processing each one using a foreach loop and retrieving the information shown in Figure 1. Here's how each of the values was obtained.
应用程序的消息循环是内部程序循环，它从线程的消息队列检索消息，然后转换这些消息，之后将它们发送给要处理的应用程序。
An application's message loop is an internal program loop that retrieves messages from a thread's message queue, translates them, and then sends them to the application to be handled.
