从XDocument删除所有评论 [英] Remove all comments from XDocument

问题描述

我正在阅读XDocument.如何从XDocument删除所有注释行.

I am working on reading XDocument. How can I remove all commented lines from XDocument.

我尝试过

 doc.DescendantNodes().Where(x => x.NodeType == XmlNodeType.Comment).Remove();

但是这只会删除带有注释的第一级节点，而内部的节点将保持原样.

But this removes only first level nodes with comments and inner level nodes remains as it is.

有什么方法可以删除所有注释行.我相信一定有！！！;)

Is there any way to remove all commented lines. I believe there must be!!! ;)

任何解决方案.

推荐答案

而不是 Where(x => x.NodeType == XmlNodeType.Comment)我会简单地使用 OfType< XComment>()，如

Instead of the Where(x => x.NodeType == XmlNodeType.Comment) I would simply use OfType<XComment>(), as in

doc.DescendantNodes().OfType<XComment>().Remove();

但是两种方法都应该删除所有级别的评论节点.

but both approaches should remove comment nodes at all levels.

这里是一个例子:

XDocument doc = XDocument.Load("../../XMLFile1.xml");

doc.Save(Console.Out);

Console.WriteLine();

doc.DescendantNodes().OfType<XComment>().Remove();

doc.Save(Console.Out);

对于示例，我得到输出

<?xml version="1.0" encoding="ibm850"?>
<!-- comment 1 -->
<root>
  <!-- comment 2 -->
  <foo>
    <!-- comment 3 -->
    <bar>foobar</bar>
  </foo>
  <!-- comment 4 -->
</root>
<!-- comment 5 -->
<?xml version="1.0" encoding="ibm850"?>
<root>
  <foo>
    <bar>foobar</bar>
  </foo>
</root>

因此所有评论均已删除.如果您仍然遇到问题，请发布示例以使我们重现问题.

so all comments have been removed. If you continue to have problems then post samples allowing us to reproduce the problem.
