HTML Agility Pack:设置HtmlNode的属性值未反映在HtmlDocument中 [英] Html Agility Pack: Setting an HtmlNode's Attribute Value isn't reflected in the HtmlDocument

问题描述

在Html Agility Pack中，当我设置HtmlNode的属性时，是否应该在从中选择节点的HtmlDocument中看到它?

In Html Agility Pack, when I set an attribute of an HtmlNode, should I see this in the HtmlDocument from which the node was selected?

可以说htmlDocument是一个HtmlDocument.因此，简化的代码如下所示:

Lets say that htmlDocument is an HtmlDocument. So the simplified code looks like this:

HtmlNode documentNode = htmlDocument.DocumentNode;
HtmlNodeCollection nodeCollection = documentNode.SelectNodes(someXPath);
foreach(var node in nodeCollection)
   if(SomeCondition(node))
       node.SetAttributeValue("class","something");

现在，我看到了节点更改的类属性，但是我没有看到此更改反映在htmlDocument的html中.

Now, I see the class attribte of node change, but I don't see this change reflected in the htmlDocument's html.

推荐答案

实际上是ProgrammerTooStupidException的一种情况:(

Actually it was a case of ProgrammerTooStupidException :(

我使用了MyHtmlPage类，该类具有Html属性和DocumentProperty.

I used a MyHtmlPage class, with an Html property and an DocumentProperty.

_html = theHtml;
_htmlDocument = new HtmlDocument();
HtmlDocument.LoadHtml(theHtml)l
_documentNode = HtmlDocument.DocumentNode;

现在，很自然地，DocumentNode对_html值没有影响.

Now, of coourse manipulation the DocumentNode had no effect on the _html value.
