Answer 1

You need to have exactly one root element, like so:

<?xml version="1.0"?>
<root>
    <apple><apple1>A</apple1></apple>
    <ball><ball1>B</ball1></ball>
    <cat><cat1>C</cat1></cat>
    <dog><dog1>D</dog1></dog>
    <ele><ele1>E</ele1></ele>
</root>

I don't know about the specifics of the parser you are using, but this is an intrinsic XML issue.

Hi,

itemDictionary is a NSMutableDictionary.

I have edited my previous answer. (currentItem is itemDictionary). In this sample code, itemDictionary is to store all values with key (when we parsing the data).

itemDictionary - {
apple1 = A
ball1 = B
cat1 = C
dog1 = D
ele1 = E
}

//--------------------------

<?xml version="1.0"?>
<root>
<apple id='10'><apple1>A</apple1></apple>
<ball><ball1>B</ball1></ball>
<cat><cat1>C</cat1></cat>
<dog><dog1>D</dog1></dog>
<ele><ele1>E</ele1></ele>
<root>

In didStartElement method, you have to use below sample code.

if([elementName isEqualToString:@"apple"]){
    NSString *attributeValue = [attributeDict objectForKey:@"id"];
    NSLog("Attribute value : %@", attributeValue);
}

I hope, it will help you.
