Use NSXMLParser

To join the string refer following function in NSArray class

- (NSString *)componentsJoinedByString:(NSString *)separator

---

to achieve XML parsing in objective-c,use NSXMLParser class and set a delegate to NSXMLParserDelegateprotocal,in the delegate implement

parser:didStartElement:namespaceURI:qualifiedName:attributes:
parser:didEndElement:namespaceURI:qualifiedName:

and

parser:foundCharacters:

methods. Each time you encounter "RadioButton" element create a mutable string. Each time you encounter end of "Item" element add the characters found so far(through foundCharacters method) to the mutable string created, with a "," at the end. Each time you encounter end of "RadioButton" remove the last character(i.e ,) from mutable string. Save the mutable strings to an array appropriately,you will have the 2 required out put strings in this array.

for comma, use this concept

itemname like NSString

ItemName = [ItemName stringByAppendingFormat:@", "];
