XDocument 正在删除文档注释

Question

当我运行<!-- This list contains names/words with specific casing - and specific to english only --> 时，将在新目的地中删除。 有什么办法可以防止它发生。我尝试使用XDocument.Root 发生同样的事情。 Ps：我知道方法不在类内:)。

<!-- This list contains names/words with specific casing - and specific to english only -->
<ignore_list>
  <name>A.M.</name>
  <name>Aaron</name>
  <name>Abbie</name>
  <name>Abi</name>
  <name>Abigail</name>
  <name>Abolfazl</name>
  <name>Adam</name>
</ignore_list>

private static void EnGBNamesEtc()
{
        var listNames = new List<string>(){"some", "names");
        var xele = XElement.Load(@"C:\Users\ivandro\Source\subtitleedit\Dictionaries\en_GB_names_etc.xml");
        var names = listNames.Except(xele.Elements("name").Select(n => n.Value)).ToList();
        foreach (var newName in names)
        {
            xele.Add(new XElement("name", newName));
        }
        SaveToNewXml(xele, @"D:\Backup\en_GB_names_etc1.xml");
}

private static void SaveToNewXml(XElement xelem, string dest)
{
    XmlWriterSettings xws = new XmlWriterSettings { OmitXmlDeclaration = true, Indent = true };
    var ordered = xelem.Elements("name").OrderBy(element => element.Value).ToList();
    using (XmlWriter xw = XmlWriter.Create(dest, xws))
    {
        xelem.ReplaceAll(ordered);
        xelem.Save(xw);
    }
}

这可能是因为您使用的 XElement 只能表示单个节点（当您有两个“根”节点时，<ignore_list> 和评论节点）。例如，使用XDocument 而不是XElement 来保留评论节点（我试图对您的原始代码进行最小的更改）：

private static async void EnGBNamesEtc()
{
        var listNames = new List<string>(){"some", "names");
        var xdoc = XDocument.Load(@"C:\Users\ivandro\Source\subtitleedit\Dictionaries\en_GB_names_etc.xml");
        var names = listNames.Except(xdoc.Root.Elements("name").Select(n => n.Value)).ToList();
        foreach (var newName in names)
        {
            xdoc.Root.Add(new XElement("name", newName));
        }
        SaveToNewXml(xdoc, @"D:\Backup\en_GB_names_etc1.xml");
}

private static void SaveToNewXml(XDocument xdoc, string dest)
{
    XmlWriterSettings xws = new XmlWriterSettings { OmitXmlDeclaration = true, Indent = true };
    var ordered = xdoc.Root.Elements("name").OrderBy(element => element.Value).ToList();
    using (XmlWriter xw = XmlWriter.Create(dest, xws))
    {
        xdoc.Root.ReplaceAll(ordered);
        xdoc.Save(xw);
    }
}
