 ＆LT;根＆GT;
  ＆其中;组件＆gt;＆所述; /组件＆gt;
＆LT; /根＆GT;
 

然而，当innerText属性有一个空字符串，它增加了一个回车符和放大器;换行未期望是什么！它结束了看起来像下面...

解决方案

这固定它，我...

xmlDoc.Load（@C：\的test.xml）;

//保存XML，然后清理
XmlWriterSettings设置=新XmlWriterSettings {缩进= TRUE};
XmlWriter的作家= XmlWriter.Create（@C：\的test.xml，设置）;
xmlDoc.Save（作家）;
 

I'm loading a XML Document that has some tags that have no innertext.

If I populate the innertext with some data then it works as needed (you get opening tag, innertext and closing tag all on one line) like the following...

<root>
  <element>value</element>
</root>

The problem arises with tags with no values. These SHOULD be displayed in the same way as above with the exception of no value of coarse, like the following...

<root>
  <element></element>
</root>

However, when the innertext has an empty string it adds a carriage return & line feed which is not what is expected! It ends up looking like the following...

<root>
  <element>
  </element>
</root>

This is my current code that yields the above results...

XmlDocument xmlDoc = new XmlDocument();
xmlDoc.Load(@"C:\test.xml");

//Save the xml and then cleanup
xmlDoc.Save(@"C:\test.xml");

解决方案

This fixed it for me...

XmlDocument xmlDoc = new XmlDocument();
xmlDoc.Load(@"C:\test.xml");

//Save the xml and then cleanup
XmlWriterSettings settings = new XmlWriterSettings { Indent = true };
XmlWriter writer = XmlWriter.Create(@"C:\test.xml", settings);
xmlDoc.Save(writer);
