“手术无法完成。（NSXMLParserErrorDomain 错误 111。

问：

我正在尝试在 Xcode 中解析 XML 字符串。它成功解析了字符串，但在它给出错误之后。

下面是 xml 字符串、解析代码和错误消息。请指导我。

先谢谢大家。

XML 字符串。

<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<soap:Body><GetProductResponse xmlns="http://searchupc.com/"><GetProductResult>"productname","imageurl","producturl","price","currency","saleprice","storename"
"Nature's Way Kids Smart Omega-3 Vita Balls X 50 Caps","http://ecx.images-amazon.com/images/I/31A5BCa%2BFvL._SL160_.jpg","","22.04","USD","","N/A"
</GetProductResult></GetProductResponse></soap:Body></soap:Envelope>

代码返回“GetProductResponse”和“soap：Body”，然后给出错误。

(void)parser:(NSXMLParser *)parser didEndElement:(NSString *)

NSLog(@"didEndElement() Element: ");
if(([elementName isEqualToString:@"GetProductResponse"]) ||
   ([elementName isEqualToString:@"soap:Body"]) ||
   ([elementName isEqualToString:@"soap:Envelope"])){

    NSLog(@"EOF Reached: %@",elementName);
    // we reach the end of product data string.
    return;
}

这是错误消息：
