HTML Agility Pack - ReplaceNode 不会更改 Body 的 InnerHTML

发布于 2024-08-28 07:31:02 字数 991 浏览 9 评论 0原文

我有这个

正文：代码

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

：

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);
}

在我执行此操作后，正文节点的 InnerHtml 与开始时保持相同，尽管 OutterHtml 或 InnerText 显示了良好的结果。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>

原文

I have this

The body:

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

The code:

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);
}

After i do this, the InnerHtml of the body node remains the same as from beginning, although the OutterHtml or the InnerText are showing the good result. Is there something wrong with my code?

The result:

// 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>

我认为这可能与您添加节点来替换旧节点的方式有关。看看这个解决方案是否适合您截断文本节点。我做了一个快速测试，所有三个都给了我相同的结果。

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);

I think it may be something to do with the way you are adding nodes to replace old nodes. See if this solution works for you to truncate the text node. I did a quick test and all three gave me the same results.

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);
