Question

我正在删除一个XML文件中的重复条目，代码正在删除它们并将值相加以使每个发票只有一个条目。但当它到达终点时，它会删除3行：

      <NumberOfEntries>11972</NumberOfEntries>
      <TotalDebit>0</TotalDebit>
      <TotalCredit>34422.86</TotalCredit>

所以不要像最终文件那样：

...
      <SourceDocuments>
        <SalesInvoices>
          <NumberOfEntries>11972</NumberOfEntries>
          <TotalDebit>0</TotalDebit>
          <TotalCredit>34422.86</TotalCredit>
          <Invoice>
            <InvoiceNo>FS 006120180101/19959</InvoiceNo>
...

看起来像是：

...
      <SourceDocuments>
        <SalesInvoices>
          <Invoice>
            <InvoiceNo>FS 006120180101/19959</InvoiceNo>
...

我的代码如下：

    using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Xml;
using System.Xml.Linq;

namespace ConsoleApplication2
{
    class Program
    {

        //Ficheiro 
        const string FILENAME = "ccc.xml";
        static void Main(string[] args)
        {
            XDocument doc = XDocument.Load(FILENAME);

            XNamespace ns = doc.Root.Name.Namespace;



            List<XElement> originalInvoices = doc.Descendants(ns + "Invoice").ToList();

            var groups = originalInvoices.GroupBy(x => (string)x.Element(ns + "Hash")).ToList();

            var finalInvoices = groups.Select(x => new
            {
                unit = x.Descendants(ns + "UnitPrice").Sum(z => (decimal)z),
                credit = x.Descendants(ns + "CreditAmount").Sum(z => (decimal)z),
                tax = x.Descendants(ns + "TaxPayable").Sum(z => (decimal)z),
                net = x.Descendants(ns + "NetTotal").Sum(z => (decimal)z),
                gross = x.Descendants(ns + "GrossTotal").Sum(z => (decimal)z),
                first = x.First()
            }).ToList();

            foreach (var finalInvoice in finalInvoices)
            {
                finalInvoice.first.Element(ns + "Line").SetElementValue(ns + "UnitPrice", finalInvoice.unit);
                finalInvoice.first.Element(ns + "Line").SetElementValue(ns + "CreditAmount", finalInvoice.credit);
                finalInvoice.first.Element(ns + "DocumentTotals").SetElementValue(ns + "TaxPayable", finalInvoice.tax);
                finalInvoice.first.Element(ns + "DocumentTotals").SetElementValue(ns + "NetTotal", finalInvoice.net);
                finalInvoice.first.Element(ns + "DocumentTotals").SetElementValue(ns + "GrossTotal", finalInvoice.gross);
            }

            doc.Descendants(ns + "SalesInvoices").FirstOrDefault().ReplaceWith(new XElement(ns + "SalesInvoices", finalInvoices.Select(x => x.first)));
            doc.Descendants(ns + "SalesInvoices").
            Console.WriteLine(doc);
            doc.Save("Root.xml");
            Console.ReadKey();

        }
    }
    }

有人可以帮我解决这个问题，如何才能删除这3行？问题可能出在写文件的最后一行，但我不确定。

doc.Descendants(ns + "SalesInvoices").FirstOrDefault().ReplaceWith(new XElement(ns + "SalesInvoices", finalInvoices.Select(x => x.first)));

问题的小更新： 好吧，我真的认为问题出在上面，因为如果我改为SalesInvoices TotalCredit，... <SourceDocuments> <SalesInvoices> <Invoice> <InvoiceNo>FS 006120180101/19959</InvoiceNo> ...是最后一行正在消失的文件仍然是错误的，而不是：

...
      <SourceDocuments>
        <SalesInvoices>
          <NumberOfEntries>11972</NumberOfEntries>
          <TotalDebit>0</TotalDebit>
          <TotalCredit>
          <Invoice>
            <InvoiceNo>FS 006120180101/19959</InvoiceNo>
...

我得到了：

34422.86</TotalCredit>

标记<Invoice>

之前缺少</TotalCredit>

并且在第一个已关闭的元素</Invoice>之后添加private lazy var foo: Void = { objc_sync_enter(self) defer { objc_sync_exit(self) } // Do this once }()，因为您可以在此处测试：Link to test the code

易于修复。只需添加缺少的3个元素：

            foreach (var finalInvoice in finalInvoices)
            {
                finalInvoice.first.Element(ns + "Line").SetElementValue(ns + "UnitPrice", finalInvoice.unit);
                finalInvoice.first.Element(ns + "Line").SetElementValue(ns + "CreditAmount", finalInvoice.credit);
                finalInvoice.first.Element(ns + "DocumentTotals").SetElementValue(ns + "TaxPayable", finalInvoice.tax);
                finalInvoice.first.Element(ns + "DocumentTotals").SetElementValue(ns + "NetTotal", finalInvoice.net);
                finalInvoice.first.Element(ns + "DocumentTotals").SetElementValue(ns + "GrossTotal", finalInvoice.gross);
            }

            XElement salesInvoices = doc.Descendants(ns + "SalesInvoices").FirstOrDefault();
            XElement numberOfEntries = salesInvoices.Element(ns + "NumberOfEntries");
            XElement totalDebit = salesInvoices.Element(ns + "TotalDebit");
            XElement totalCredit = salesInvoices.Element(ns + "TotalCredit");

            salesInvoices.ReplaceWith(new XElement(ns + "SalesInvoices", new object[] {
                numberOfEntries,
                totalDebit,
                totalCredit,
                finalInvoices.Select(x => x.first)
            }));

当写入文件3行被删除时，不应该删除
