- (void)traverseElement:(TBXMLElement *)element {
do {
    NSLog(@"%@",[TBXML elementName:element]);
    if (element->firstChild) 
        [self traverseElement:element->firstChild];


    TBXMLAttribute * attribute = element->firstAttribute;

    // if attribute is valid
    while (attribute) {
        // Display name and value of attribute to the log window
        NSLog(@"%@->%@ = %@",
              [TBXML elementName:element],
              [TBXML attributeName:attribute],
              [TBXML attributeValue:attribute]);

        // Obtain the next attribute
        attribute = attribute->next;
    }

    if ([[TBXML elementName:element] isEqualToString:@"order"]) {
        NSLog(@"xml element checking");
        TBXMLElement *order_id = [TBXML childElementNamed:@"id" parentElement:element];
        TBXMLElement *order_date = [TBXML childElementNamed:@"order_date" parentElement:element];
        TBXMLElement *customer = [TBXML childElementNamed:@"customer" parentElement:element];

        TBXMLElement *customer_id = [TBXML childElementNamed:@"id" parentElement:customer];
        TBXMLElement *customer_name = [TBXML childElementNamed:@"name" parentElement:customer];
        [records addObject:[NSArray arrayWithObjects:
                            [TBXML textForElement:customer_id],
                            [TBXML textForElement:customer_name],
                            [TBXML textForElement:order_id],
