iphone - 将 XML 解析为 NSMutableArray

Question

我的 Web 服务中有以下格式的 XML。

<xml>
    <Menu>
        <pair>
            <MenuCategory shortname="Starters Menu" description_en="hgfhghgh" image="Small.jpg" description_fr="" description_ge="" description_it="" description_sp="" description_ch="">
                <MenuItems>
                    <menuItem price="666" image="060649XSmall.jpg" shortname="kandan" description_en="kandan" description_fr="" description_ge="" description_it="" description_sp="" description_ch=""/>
                    <menuItem price="250" image="3.jpg" shortname="Vegetable Soups" description_en="Vegetable Soups" description_fr="" description_ge="" description_it="" description_sp="" description_ch=""/>
                    <menuItem price="52" image="3.jpg" shortname="Mixed Starters" description_en="Mixed Starters" description_fr="" description_ge="" description_it="" description_sp="" description_ch=""/>
                    <menuItem price="45" image="14.jpg" shortname="Pumpkin soup" description_en="Pumpkin soup" description_fr="" description_ge="" description_it="" description_sp="" description_ch=""/>
                    <menuItem price="15" image="15.jpg" shortname="Almondrolledgoatsche" description_en="Almondrolledgoatsche" description_fr="" description_ge="" description_it="" description_sp="" description_ch=""/>
                </MenuItems>
            </MenuCategory>
        </pair>
    </Menu>
</xml>

我已尝试使用 TBXML 从我的网络服务中解析此 XML。但是，还没有得到我的输出，

TBXML *XML = [[TBXML alloc]initWithURL:[NSURL URLWithString:urlString]];
TBXMLElement *rootXML = XML.rootXMLElement;
TBXMLElement *e = [TBXML childElementNamed:@"MenuItems" parentElement:rootXML];
NSString *woeid = [TBXML textForElement:e->firstChild];
NSLog(@"Woeid - %@", woeid);    

它简单地抛出 EXEC_BAD_ACCESS 错误。我只需要将此 xml 解析为我的 NSMutableArray 有很多与此相关的示例。但是，不知道哪个适合我的要求。有人以这种格式工作过吗？知道如何实现吗？

您可以使用 XMLReader将 xml 数据解析为 NSDictionary 或 NSArray 或 MutableArray 的文件。将其用作:

NSError *error=nil;

NSString *responseString=[NSString stringWithFormat:@"<xml><Menu><pair><MenuCategory shortname=\"Starters Menu\" description_en=\"hgfhghgh\" image=\"Small.jpg\" description_fr=\"\" description_ge=\"\" description_it=\"\" description_sp=\"\" description_ch=\"\"><MenuItems><menuItem price=\"666\" image=\"060649XSmall.jpg\" shortname=\"kandan\" description_en=\"kandan\" description_fr=\"\" description_ge=\"\" description_it=\"\" description_sp=\"\" description_ch=\"\"/><menuItem price=\"250\" image=\"3.jpg\" shortname=\"Vegetable Soups\" description_en=\"Vegetable Soups\" description_fr=\"\" description_ge=\"\" description_it=\"\" description_sp=\"\" description_ch=\"\"/><menuItem price=\"52\" image=\"3.jpg\" shortname=\"Mixed Starters\" description_en=\"Mixed Starters\" description_fr=\"\" description_ge=\"\" description_it=\"\" description_sp=\"\" description_ch=\"\"/><menuItem price=\"45\" image=\"14.jpg\" shortname=\"Pumpkin soup\" description_en=\"Pumpkin soup\" description_fr=\"\" description_ge=\"\" description_it=\"\" description_sp=\"\" description_ch=\"\"/><menuItem price=\"15\" image=\"15.jpg\" shortname=\"Almondrolledgoatsche\" description_en=\"Almondrolledgoatsche\" description_fr=\"\" description_ge=\"\" description_it=\"\" description_sp=\"\" description_ch=\"\"/></MenuItems></MenuCategory></pair></Menu></xml>"];

NSDictionary *dictionary=[XMLReader dictionaryForXMLString:responseString error:&error];

NSLog(@"dictioanry is %@",dictionary);

NSMutableArray *menuItemsArray=[[NSMutableArray alloc] initWithArray:[[[[[[dictionary valueForKey:@"xml"] valueForKey:@"Menu"] valueForKey:@"pair"] valueForKey:@"MenuCategory"] valueForKey:@"MenuItems"] valueForKey:@"menuItem"]];

NSLog(@"menu item array is %@",menuItemsArray);
