When I try to parse the XML file using NSXMLParser I could not parse all the elements .. XML response looks like this:

<AList>
   <Details>
          <AId>1</AId>
          <Date>10/31/2012</Date>
          <Time>11:00 AM</Time>
       <User>
          <Employee>
              <Name>Rosy</Name>
              </Employee>
              <Company>
                  <Customer>
                     <CustName>Williams</CustName>
                     <CustPhone>1232322</CustPhone>
                 </Customer>
             </Company>
       </User>
  </Details>
<Details>
          <AId>2</AId>
          <Date>10/31/2012</Date>
          <Time>11:30 AM</Time>
       <User>
          <Employee>
              <Name>Mary</Name>
              </Employee>
              <Company>
                  <Customer>
                     <CustName>Christopher</CustName>
                     <CustPhone>123233323</CustPhone>
                 </Customer>
             </Company>
       </User>
  </Details>
</AList>

How can I get all the elemnts in all the XML tags?

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


if([elementName isEqualToString:@"AList"])
{
    arr=[[NSMutableArray alloc] init];



}
    if([elementName isEqualToString:@"Details"]||[elementName isEqualToString:@"User"])
    {
        drr=[[NSMutableDictionary alloc] init];
    }

srr=[[NSMutableString alloc] init];

} 


-(void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string{


    [srr appendString:string];
}


- (void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName {

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

        [drr setObject:srr forKey:@"AId"];
        [srr release],srr=nil;
        return;
    }  

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

        [drr setObject:srr forKey:@"Date"];
        [srr release],srr=nil;
       return;    
    }
    if([elementName isEqualToString:@"Time"])
    {

        [drr setObject:srr forKey:@"Time"];
        [srr release],srr=nil;
     return;      
    }
    if([elementName isEqualToString:@"Name"])
    {

        [drr setObject:srr forKey:@"Name"];
        [srr release],srr=nil;
        return;
    }
        if([elementName isEqualToString:@"CustName"])
    {
        [drr setObject:srr forKey:@"CustName"];
        [srr release],srr=nil;


       return;
    }

    if([elementName isEqualToString:@"CustPhone"])
    { 
        [arr addObject:drr]; 

    }    



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

        [drr release];


    }

    [srr release],srr=nil;

}

I dont want CustPhone...I couldget only CustName from the code i have written.Where Im going wrong?

</Alist>TAGは<AList>- 'L'とは異なります。そうしないと、NSXMLParserは、didFoundCharactersデリゲートで他のすべてのタグデータを適切に解析することができます。

ここに文字列比較の問題があります 

- (void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName {

if([elementName isEqualToString:@"AList"]) // in ur xml it is Alist
{

    [drr release];

}

これを変更してください

    if([elementName isEqualToString:@"Details"]||[elementName isEqualToString:@"User"])
    {
        drr=[[NSMutableDictionary alloc] init];
    }

に

   if([elementName isEqualToString:@"Details"])
    {
        drr=[[NSMutableDictionary alloc] init];
    }

顧客の電話要素が見つかったら、辞書を配列に追加します。辞書を2回割り当てています。「詳細」タグと「ユーザー」タグが見つかった場合。
