Parsing XML Data in Core Data

I am trying to extract data from an online xml file and put it in my master data.

I can successfully retrieve the data and I can even put it inside the main data, but it seems that only the last received channel is saved.

Here is an example xml file I am trying to extract.

Parser code example:

    func parser(parser: NSXMLParser, didEndElement elementName: String, namespaceURI: String?, qualifiedName qName: String?) {
        if (elementName as NSString).isEqualToString("question") {
            if !xml_tmp1.isEqual(nil) {
                elements.setObject(xml_tmp1, forKey: "text")
            }
            if !xml_tmp2.isEqual(nil) {
                elements.setObject(xml_tmp2, forKey: "answer0")
            }

            if !xml_tmp3.isEqual(nil) {
                elements.setObject(xml_tmp3, forKey: "answer1")
            }

            if !xml_tmp4.isEqual(nil) {
                elements.setObject(xml_tmp4, forKey: "answer2")
            }

            if !xml_tmp5.isEqual(nil) {
                elements.setObject(xml_tmp5, forKey: "answer3")
            }
            tmp_xml.addObject(elements)
        }
    }

      

        
        
        
      

    

Sample master data code:

    func temp_func() {
        var n: Int = tmp_xml.count
        var i: Int = 0

        var appDel: AppDelegate = (UIApplication.sharedApplication().delegate as! AppDelegate)
        var context: NSManagedObjectContext = appDel.managedObjectContext!

        var tmp = NSEntityDescription.insertNewObjectForEntityForName("Questions", inManagedObjectContext: context) as! NSManagedObject

        while (i != br) {
            tmp.setValue(tmp_xml.objectAtIndex(i).valueForKey("text"), forKey: "question")
            tmp.setValue(tmp_xml.objectAtIndex(i).valueForKey("answer0"), forKey: "answer_1")
            tmp.setValue(tmp_xml.objectAtIndex(i).valueForKey("answer1"), forKey: "answer_2")
            tmp.setValue(tmp_xml.objectAtIndex(i).valueForKey("answer2"), forKey: "answer_3")
            tmp.setValue(tmp_xml.objectAtIndex(i).valueForKey("answer3"), forKey: "answer_4")

            i++
        }

        context.save(nil)
    }

      

        
        
        
      

    

Basically, I should get three new records in my master data, but only the last one is kept (question 15 * 7).
