[已解决]保留“\ n” XmlNode.InnerText中的字符 [英] [Solved] Retaining "\n" character in XmlNode.InnerText

问题描述

我有一个winform应用程序，允许用户操作xml文件。 xml文件包含描述节点，我在多行文本框中显示该节点。然后用户可以通过添加回车等来编辑描述。



当我使用文本框中的值重置描述node.InnerText时，它不会保留\ n字符。当我打开xml文件时，我需要innerText的值来包含实际的字符\ n，即

这是第一行\ n这是第二行\ n



当我调试代码并查看textbox.Text的值时，我可以在视觉上看到\ n字符但在设置节点之后。 InnerText = textbox.text，\ n不可见，在xml文件中也不可见。



我试过node.InnerText.Replace（ Enviornment.NewLine，\ n）在我设置了InnerXml但它没有效果。



还有其他任何想法吗？

谢谢！



更新：

由OP自己解决 - 张贴为答案之一。

I have a winform app that allows the user to manipulate a xml file. The xml file contains a description node and I display that node in a multiline text box. The user can then edit the description by adding carriage returns etc.

When I go to reset the description node.InnerText with the value from the textbox, it does not retain the "\n" character. When I open the xml file, I need the value of the innerText to contain the actual character "\n" i.e.
This is the first line\nThis is the second line\n

When I am debugging the code and I look at the value of the textbox.Text, I can visually see the "\n" characters but after I set the node.InnerText = textbox.text, the "\n" are not visible and are not visible in the xml file either.

I have tried node.InnerText.Replace(Enviornment.NewLine,"\n") after I set the InnerXml but it has no effect.

Any other ideas?
thanks!

推荐答案

对不起，我是傻瓜...当我设置node.InnerText时我最终做了：

node.InnerText = value.Replace（Envirnment.Newline，\\\ \\ n;



我忘了逃避\ n，一旦我添加了\\ n，然后在xml中显示了\ n字符。



无论如何谢谢！

Sorry, I was stupid... When I set the node.InnerText I ended up doing :
node.InnerText = value.Replace(Envirnment.Newline, "\\n";

I forgot to escape the \n, once I added the \\n, then the \n character showed up in the xml.

Thanks anyway!

我无法使用以下测试代码重现您的问题：

I could not reproduce your problem with the following test code:

static void Main(string[] args)
{
  XmlDocument doc = new XmlDocument();
  XmlNode node = doc.CreateNode(XmlNodeType.Element, "Test", "");
  node.InnerText = "hello\nworld";
  doc.AppendChild(node);
  Console.WriteLine(doc.InnerXml);
}

将文本包装在CDATA节点中应该可以解决问题。当从XML文件中读回数据时，这将保留回车。



干杯！

Wrapping the text in a CDATA node should do the trick. That will preserve the carriage returns when the data is read back from the XML file.

Cheers!
