我想通过插入第二个XML文档到年底合并两个的XmlDocument 秒的现有 XMLDOCUMENT 的C＃。这是怎么做的？

I want to merge two XmlDocuments by inserting a second XML doc to the end of an existing Xmldocument in C#. How is this done?

推荐答案

事情是这样的：

foreach (XmlNode node in documentB.DocumentElement.ChildNodes)
{
    XmlNode imported = documentA.ImportNode(node, true);
    documentA.DocumentElement.AppendChild(imported);
}

请注意，这忽略了文档元素B文件本身 - 所以，如果说有不同的元素名称或属性要复制过来，你需要制定出你想要做什么

Note that this ignores the document element itself of document B - so if that has a different element name, or attributes you want to copy over, you'll need to work out exactly what you want to do.

编辑：如果按你的意见，你要嵌入的整个文件A中的B文件的，这是比较容易的：

If, as per your comment, you want to embed the whole of document B within document A, that's relatively easy:

XmlNode importedDocument = documentA.ImportNode(documentB.DocumentElement, true);
documentA.DocumentElement.AppendChild(importedDocument);

这仍然会忽略的东西像B文件的XML声明，如果存在的话 - 我不知道会发生什么，如果你试图导入文件的自身的作为不同的文档的节点，它包括一个XML声明...但我怀疑这会做你想要的。

This will still ignore things like the XML declaration of document B if there is one - I don't know what would happen if you tried to import the document itself as a node of a different document, and it included an XML declaration... but I suspect this will do what you want.
