为元素节点解析 XML 文件，然后将文本存储在不同的数组中以加载到 Excel

Question

我想解析我将从亚马逊收到的 XML 文件，然后获取数据并将其输入 Excel 中的自定义发票并打印。

我已经完成了这项任务的大部分，但是当客户的地址部分有 2 个部分（例如 <AdressLine1> 和 <AddressLine2> 时，我运行遇到了困难字段，然后我的两个数组不相等，当我尝试将值写入 excel 单元格时，它会在 excel_create 中的循环中引发错误。

这是我的示例 XML 文件：

                        xlCell4.Value2 = d[i] + ", " + e[i];
                    }

                }
                xlWorksheet.PrintOutEx();

            }
            catch (Exception ex)
            {
                xlApp.Quit();

            }
        }
    }
}

if(c[i] != null) 每当此测试失败时，我都会收到错误消息。我相信这是因为当我存储 AddressLine2 节点时，它不会创建与我的其余数组大小相同的数组，因为只有一个客户有第二个地址。

无论如何，我们将不胜感激。

Answer 1

您是对的，AddressLine2 是您的问题，因为只有您的一个客户有第二个地址行。您需要确保 return 每个不包含此元素的地址都有一个空行（否则您将不知道哪个 AddressLine2 与哪个地址相关） - 这不是很简单您如何阅读 XML.

以这种方式编写代码容易出现此类错误，并且某些命名会影响可读性。例如，将您的 collections/arrays 命名为 collection1、collection2 或 a、b、c 意味着您必须不断上下滚动以查看弄清楚它们实际代表什么。

将它们命名为 names、cities 等将是一种改进，但更好的是，为什么不创建一个 Address class？

public class Address
{
    public string Name { get; set; }
    public string AddressLine1 { get; set; }
    public string AddressLine2 { get; set; }
    public string City { get; set; }
    public string StateOrRegion { get; set; }    
}

然后，不用在 Parse 中使用大量 copy/paste 代码，只需使用 LINQ to XML 来创建您的 Address 对象。

private static IEnumerable<Address> Addresses(XContainer doc)
{
    XNamespace ns = "https://mws.amazonservices.com/Orders/2013-09-01";

    return from address in doc.Descendants(ns + "ShippingAddress")
           select new Address
           {
               Name = (string)address.Element(ns + "Name"),
               AddressLine1 = WebUtility.HtmlDecode((string)address.Element(ns + "AddressLine1")),
               AddressLine2 = (string)address.Element(ns + "AddressLine2"),
               City = (string)address.Element(ns + "City"),
               StateOrRegion = (string)address.Element(ns + "StateOrRegion"),
           };
}

请注意，您可以使用 WebUtility.HtmlDecode 来解码双重转义文本（例如，将 THE BOTIQUE &amp; TAPES 解码为 THE BOTIQUE & TAPES）。这可能适用于所有行而不仅仅是 AddressLine1.

然后你可以用这样的签名实现你的 Excel 书写方法：

private static void WriteToExcel(IEnumerable<Address> addresses)

我将离开实施，因为不清楚你在 Excel_Create 中做什么 - 它似乎每次都重复覆盖 sheet 中的值的所有客户地址，所以我'我不确定目前的情况是否正确。

您的主要方法将减少为：

var path = Path.Combine(Directory.GetCurrentDirectory(), "Perls.xml");

var doc = XDocument.Load(path);

var addresses = Addresses(path);

WriteToExcel(addresses);

这里有一个将所有内容放在一起的工作演示：https://dotnetfiddle.net/k1AJ8H。这从 XML 字符串中读取并将地址写入控制台
