Question

我有这个

身体：

<body><p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Praesent leo leo, ultrices eu venenatis et, rutrum fringilla dolor.</p></body>

代码：

HtmlNode body = doc.DocumentNode.SelectSingleNode("//body");

Dictionary<HtmlNode, HtmlNode> toReplace = new Dictionary<HtmlNode, HtmlNode>();

// I do some logic here adding nodes to the toReplace dictionary.

foreach (HtmlNode replaceNode in toReplace.Keys)
{
    replaceNode.ParentNod.ReplaceChild(toReplace[replaceNode], replaceNode);
}

执行此操作后，尽管OutterHtml或InnerText显示出良好的结果，但身体节点的InnerHtml仍然与开头相同。我的代码有问题吗？

结果：

// body.InnerHtml
<p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Praesent leo leo, ultrices eu venenatis et, rutrum fringilla dolor.</p>

// body.OutterHtml
<body><p>Lorem ipsum dolor sit amet...</p></body>

我认为这可能与添加节点以替换旧节点的方式有关。查看此解决方案是否适用于截断文本节点。我做了一个快速测试，所有三个给了我相同的结果。

HtmlDocument doc = new HtmlDocument();
doc.LoadHtml(htmlString);
HtmlNode body = doc.DocumentNode.SelectSingleNode("//body");

foreach (var paragraph in body.Descendants("p"))
{
    paragraph.InnerHtml = paragraph.InnerHtml.Substring(0, 25) + "...";
}

Console.WriteLine(body.InnerHtml);
Console.WriteLine(body.InnerText);
Console.WriteLine(body.OuterHtml);
