具有多个委托的NSXMLParser [英] NSXMLParser with multiple delegates

问题描述

我正在尝试解析带有多个NSXMLParserDelegate解析器的xml树文件，但是我遇到了下一个问题.

I'm trying to parse an xml tree file whith multiple NSXMLParserDelegate parsers but I'm getting in the next issue.

我的XML结构就是这样.

My XML structure is something like that.

<Object1>
     <Name>Ricky</Name>
     <Surname>Woodstock</Surname>
     <Adress>
          <City>Los Angeles</City>
          <State>California</State>
          <Country>USA</Country>
     </Adress>
     <Items>
          <Item>
               <Id>1</Id>
               <Description>Sports Bag</Description>
               <Price>13.45</Price>
          </Item>
          <Item>
               <Id>2</Id>
               <Description>Baseball Cap</Description>
               <Price>6.90</Price>
          </Item>
     </Items>
     <Total>20.15</Total>
</Object1>

我的问题是，当我更改委托时，它开始不在顶级标签中进行解析，而是开始在第一个嵌套标签上进行解析.

And my Issue is that when I changes delegates, it starts parsing not in top-level tag, instead it begins parsing on the first nested tag.

例如.

1. 我开始使用可解析元素的XMLObject解析器解析XML

1. I begin parsing XML wih XMLObject parser which parses element

当到达Adresss标记时，我将委托设置为XMLAdressParser(并将XMLAdressParser的父对象设置为self以返回)，但是XMLAdressParser开始在标记上进行解析.

When it reaches Adresss tag I set delegate to XMLAdressParser (and set XMLAdressParser's parent to self for returning) but XMLAdressParser begins parsing on tag.

几乎包含Items和Item标签.

And almost with Items and Item tags.

我认为这是解析器定义的正​​常原因，但这是问题所在:

I think it's normal cause of a Parser definition, but that's the question:

有没有办法让委托像第一个一样开始在对应的标记中进行解析?

Is there any way for the delegate to start parsing in correspondint tag, like first one?

在此先感谢您的帮助.

推荐答案

我建议不要使用多个委托，而应该使用单个委托并让它在您认为合适的情况下分发工作.

Rather than using multiple delegates I suggest using a single delegate and having it distribute the work as you feel appropriate.
