iPhone中的GDataXml解析问题

Question

下面是我在iOS中使用GDataXml解析区段和Company Sub数据所需的代码。

-<MainList>
    <FirstMessage>Right</FirstMessage>
    <SecondMessage>Wrong</SecondMessage>
    <Status>0</Status>
   -<CompanyList>
     -<Company>
         <Address1>12447 Hedges Run Drive</Address1>
         <Address2>#B-1 </Address2>
         <City>Lake Ridge</City> 
         <CompanyName>Starbucks</CompanyName>
         <CreatedBy>example@example.com</CreatedBy>
     -</Company>
      -<Company>
         <Address1>12447 Hedges Run Drive</Address1>
         <Address2>#B-1 </Address2>
         <City>Lake Ridge</City>
         <CompanyName>Starbucks</CompanyName>
         <CreatedBy>example@example.com</CreatedBy>
      -</Company>
   </CompanyList>
</MainList>

这是我的尝试，我得到的一切都很好，但我在NSArray arr中什么也得不到。

  NSArray *channels = [rootElement elementsForName:@"CompanyList"];  
  for (GDataXMLElement *icon in channels) {  
  NSArray *arr = [icon elementsForName:@"Company"];  
  if ([arr count]>0)  
  {  
        NSlog(@"Done");  
  }  
}

大家好，我想出了下面的方法

GDataXMLDocument *xmlDocument = [GDataXMLDocument allocinitWithData:xmlData选项:0错误：&错误]；

NSLog(@"Error:%@",[error description]);

NSArray *getData = [[xmlDocument rootElement]elementsForName:@"CompanyList"];
NSArray  *tempArray = [[NSMutableArray alloc]init];

for(GDataXMLElement *e in getData)
{

    NSArray *el = [e elementsForName:@"Company"];

    for (GDataXMLElement *e in el) {
        static int count =0;
        NSString    *testString = [[[e elementsForName:@"Address1"] objectAtIndex:0] stringValue];
        NSLog(@"Company  %d  : %@",count+1, testString);

    }
