解析器元素与子元素
例如，我有此文档:
<Category>
<Name>NameParent</Name>
<Category>
<Category>
<Name>NameChild1</Name>
<Category>
<Name>NameChild2</Name>
</Category>
</Category>
</Category>
</Category>
这是我的课程:
class Category: NSObject {
var attributeID:NSString = ""
var nameCategory:NSString = "nameNotFound"
var objCategory:Category?
}
如何查看类别是一个递归类.
how to see category is a recursive class.
这些孩子可能又有其他孩子，并且孩子人数不限，我该如何处理? 如何在解析器中构造它?
the children may have, in turn, other children, and have an unlimited number how can I handle this? how can I structure this in the parser?
目前，解析器无法找到父亲和他们的孩子，但我无法将它们很好地保存在列表中.
at this time, the parser can not find the father and their children, but I can not save them well in the list.
谢谢
我将使用某种堆栈来实现它.在每个打开的<Category>上，将一个新元素推入堆栈，然后在每个</Category>上，弹出堆栈中的最后一个元素.
I would implement this with some kind of stack. On each open <Category> push a new element on the stack and on each </Category> pop the last one from the stack.
一种简单的方法是对堆栈使用数组.
One simple approach is to use an array for the stack.
为类别元素创建一个类.解析时，每当didStartElement用elementName == "Category"触发时，都会创建该类的新实例，并进行进一步的处理，直到didEndElement触发，再用elementName == "Category"
Create a class for the category elements. While parsing, whenever didStartElement fires with elementName == "Category" create a new instance of that class and do the further processing until didEndElement fires, again with elementName == "Category"
