分割大型XML文件时遇到问题。当我生成要插入新的小文件的新元素（从原始文件复制）时，它们都以<at:

开头

例如，我的根元素如下所示：<at:export

而不是：<export

它们与Unix LF具有相同的编码（UTF-8）。

任何知道原因的人吗？

修改：我的分割函数中的代码

public List<XDocument> SplitXML(string sourceFile, string chunkNode, int chunkSize)
    {
        var smallXMLs = new List<XDocument>();

        Console.WriteLine("Start reading XML document...");
        XDocument document = XDocument.Load(sourceFile);

        XElement content = (XElement)document.Root.LastNode;


        Console.WriteLine("Generating chunk docs...");
        var ids = content.Elements();
        XDocument newRequest = null;
        XElement root = null;
        XElement items = null;
        int i = 1;
        do
        {
            root = new XElement(document.Root.Name, document.Root.Attributes());
            items = new XElement(chunkNode);
            foreach (XElement myElement in document.Root.Nodes())
            {
                if (myElement.Name.LocalName != chunkNode)
                    root.Add(myElement);

            }
            newRequest = new XDocument();
            newRequest.Add(root);

            var chunk = ids.Take(chunkSize);
            items.Add(chunk);
            newRequest.Root.Add(items);
            chunk.Remove();
            smallXMLs.Add(newRequest);

            i++;
        } while (ids.Any());

        Console.WriteLine("Document {0} generated", i.ToString());

        return smallXMLs;
    }

我通常会遵循以避免名称空间问题：

            string xml =
                "<?xml version=\"1.0\" encoding=\"utf-8\" ?>" +
                "<export xsi:schemaLocation=\"http://www.arcticgroup.se/tariff/arctictariff/export Measure.xsd \"" +
                " xmlns=\"http://www.arcticgroup.se/tariff/arctictariff/export\"" +
                " xmlns:at=\"http://www.arcticgroup.se/tariff/arctictariff/export\"" +
                " xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\">" +
                "</export>";

            XDocument newRequest = XDocument.Parse(xml);

XElement生成以“<at：”开头的名称
