为什么我的字典里的Children没有填满

大家好，我正在使用 NSXMLParser 来解析一些 xml 数据。我正在使用这些数据构建树表示，以创建钻取表的层次结构。

- (void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName 
  namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qualifiedName 
 attributes:(NSDictionary *)attributeDict {

 if([elementName isEqualToString:@"exercises"]) {
   //init tree 
  appDelegate.Tree = [NSMutableDictionary new];
  appDelegate.Rows = [NSMutableArray new];
  [appDelegate.Tree setObject:appDelegate.Rows forKey:@"Rows"];
   ...

现在，如果我的 xml 中的元素 menuitem 被读取，那么它将初始化并将 theChildren 添加到 menu_item 字典中

if([elementName isEqualToString:@"menuitem"]) {


  appDelegate.theChildren = [NSMutableArray new];
  [appDelegate.menu_item setObject:appDelegate.theChildren forKey:@"Children"];

这一切都按计划进行。

然而，以下内容并没有按照我想要的方式进行。当我看到另一个标签（workout_mob）时，我希望填充 theChildren，而这只发生在底部词典项目中。

if([elementName isEqualToString:@"workout_mob"]) {

  appDelegate.work_out_mob = [NSMutableDictionary new];


  [appDelegate.theChildren addObject:appDelegate.work_out_mob];

有谁知道为什么它至少没有填充我的两个项目吗？我的意思是它将 Children 数组添加到它们两个中，所以为什么只为其余的底部一个。如果我在 xml 代码中添加另一个 xmlline，如下所示：

<menu_mob>
   <menuitem id="1" text="Press this for exercises" pic="workout" />
   <menuitem id="2" text="VirtuaGym online" pic="online" />
                    *<menuitem id="3" text="the Added Line" pic="online" />*
 </menu_mob>

那么它会将所有子项添加到底部菜单项（想象另一个字典项 (3)）。那么为什么呢？

Hello all I'm using NSXMLParser to parse some xml data.
I'm using this data to build a Tree representation to create a hierarchy for a drilldowntable.

- (void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName 
  namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qualifiedName 
 attributes:(NSDictionary *)attributeDict {

 if([elementName isEqualToString:@"exercises"]) {
   //init tree 
  appDelegate.Tree = [NSMutableDictionary new];
  appDelegate.Rows = [NSMutableArray new];
  [appDelegate.Tree setObject:appDelegate.Rows forKey:@"Rows"];
   ...

Now if the element menuitem in my xml is being read then it will initialize and add theChildren to the menu_item dictionary

if([elementName isEqualToString:@"menuitem"]) {


  appDelegate.theChildren = [NSMutableArray new];
  [appDelegate.menu_item setObject:appDelegate.theChildren forKey:@"Children"];

This is all going according to plan.

However the following is not going the way I want it to go.
When I see another tag (workout_mob) I want theChildren to be filled and this only happens with the bottom dictionary item.

if([elementName isEqualToString:@"workout_mob"]) {

  appDelegate.work_out_mob = [NSMutableDictionary new];


  [appDelegate.theChildren addObject:appDelegate.work_out_mob];

Does anyone have a clue as to why it isn't at least filling both my items I mean it's adding the Children array to the both of them so why just the bottom one for the rest. If I add another xmlline in my xml code like so:

<menu_mob>
   <menuitem id="1" text="Press this for exercises" pic="workout" />
   <menuitem id="2" text="VirtuaGym online" pic="online" />
                    *<menuitem id="3" text="the Added Line" pic="online" />*
 </menu_mob>

then it will add all the Children items to the bottom menuitem ( imagine another dictionary item (3)).
So why ?
