Node 2 sends its integer to node 1, and node 4 sends its integer to node 3.

节点2将自己的整数发送给节点1，节点4将自己的整数发送给节点3。

Node types are returned as integers, and allow you to handle each node appropriately; an element (type 1) has a name, but no value, whereas a text node (type 3) has a value but no name.

节点类型以整数返回，并且允许您适当地处理每一个节点；一个元素(类型1)有名称没有值，但是一个文本节点(类型3)有值没有名称。

Next, at point (3), the user exit is invoked after the node processing is completed.

接下来在点(3)处，在节点处理完成后调用了用户出口。

We can look at the 2 p, which should have one radial node, and we just figured it out for the, excuse me, 3d for the 3 p has one radial node, and for the 3 d here, we should have zero radial nodes, we just calculated that.

我们看2p，它有一个节点，我们已经知道对于，不好意思，是3p有一个节点，对于，它应该没有径向节点，我们刚刚算过这个。
