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.
