C#HtmlAgilityPack内部html附加节点后不更改 [英] C# HtmlAgilityPack inner html dont change after appending node

问题描述

在我的C#中，我更改了已加载的html，并且需要以纯文本格式获取html文档.但是，每当我将新节点追加到文档的节点之一时，即使成功添加了新节点，根节点的内部html也不会更改.调试后，我注意到只有新节点的父节点的InnerHtml属性有所更改，例如:

In my C# i change loaded html, and need to get html document as plain text. But whenever i append new node to one of document's node, the inner html of root node doesn't change, even if the new node is successfully added. After debugging i noticed that only the parents of new node has the change in their InnerHtml property, for example:

HtmlDocument doc;
HtmlNode root doc.DocumentNode;
HtmlNode node2 = root.ChildNodes[1];
HtmlNode newNode = new HtmlNode(...);
node2.Append(newNode);

具有:

<root>
    <node1>
    </node1>
    <node2>
        <node3>
        <node3>
        <newNode>
        </newNode>
    </node2>
</root>

node2.InnerHtml将是

node2.InnerHtml will be

        <node3>
        <node3>
        <newNode>
        </newNode>

但是root.InnerHtml是

but root.InnerHtml is

<root>
    <node1>
    </node1>
    <node2>
        <node3>
        <node3>
    </node2>
</root>

我该如何解决此问题?(我知道我可以手动更新每个文档的节点内部html，但很常见...)

How can i fix this right? ( i know i could manually update every document's node inner html, but common... )

推荐答案

我已经通过使用方法 WriteContentTo()而不是使用属性 InnerHtml 或 OuterHtml

I have solved this issue by using method WriteContentTo() instead of using properties InnerHtml or OuterHtml
