有没有什么方法可以保存XmlDocument *没有*缩进和换行符? [英] Is there any way to save an XmlDocument *without* indentation and line returns?

问题描述

我所有的搜索都引起了人们的反驳，但是如果保存为带有行返回和缩进的文件，我的文件将增长近50％.

All my searches have brought up people asking the opposite, but I have a file which grows by nearly 50% if it is saved with line returns and indentation.

有什么办法解决这个问题吗?

Is there any way round this?

编辑，我不是在谈论打开文件，而是保存一个文件.这段代码为我重现了"bug":

EDIT I'm not talking about opening a file, but saving one. This code reproduces the 'bug' for me:

var path = @"C:\test.xml";
System.IO.File.WriteAllText(path, "<root>\r\n\t<line></line>\r\n\t<line></line>\r\n</root>");
System.Xml.XmlDocument doc = new System.Xml.XmlDocument();
doc.PreserveWhitespace = false;
doc.Load(path);
doc.PreserveWhitespace = false; //just in case!
doc.Save(path);

中间的断点表明doc.InnerXml实际上是< root>< line></line< line></line></root< code> ;,如预期的那样.但是最后 test.xml 的内容是:

A breakpoint in the middle shows that doc.InnerXml is effectively <root><line></line><line></line></root>, as expected. But the contents of test.xml at the end is:

<root>
  <line>
  </line>
  <line>
  </line>
</root>

推荐答案

尝试以下代码:

XmlDocument doc = new XmlDocument();

using(XmlTextWriter wr = new XmlTextWriter(fileName, Encoding.UTF8))
{
    wr.Formatting = Formatting.None; // here's the trick !
    doc.Save(wr);
}
