Html Agility Pack - New HtmlAttribute

由 谁都会走 提交于 2019-12-06 22:34:12
问题 Using Html Agility Pack in C# I have a node I'd like to add an attribute to. Currently the node is an <li> element with no attributes and I'd like to add a class to it of "active". It looks like the best thing to use would be node.Attributes.Add(attrClass) Where attrClass is a HtmlAttribute of class="active" . However if I try to define a new HtmlAttribute I get an error stating that it doesn't have any constructors. Eg HtmlAttribute attrClass = new HtmlAttribute(); Is there something wrong

问题 I am using following method to strip all html from the string: public static string StripHtmlTags(string html) { if (String.IsNullOrEmpty(html)) return ""; HtmlAgilityPack.HtmlDocument doc = new HtmlAgilityPack.HtmlDocument(); doc.LoadHtml(html); return doc.DocumentNode.InnerText; } But it seems ignoring this following tag: […] So the string returns basicly: > A hungry thief who stole a rack of pork ribs from a grocery store has > been sentenced to spend 50 years in prison.

Delete all elements between two elements

由 孤者浪人 提交于 2019-12-06 15:28:41
I have about 2500 html-files of different standards. I need to remove the footer part of them. The HTML-code below is one of my files footer, and I need to remove the two hr-elements and the elements between the two. So far I have only tried targeting the hr-element with xpath (and HTML Agility Pack) selectSingleNode and DocumentNode.SelectNodes("//hr"); . And then try to iterate with a foreach. But I am too much of a noob to use XPath properly, and don't know how to select the node and its siblings(?) to delete them. This is what I've got so far, with the help of this community. :) private

C# htmlagility pack, capturing redirct

由 血红的双手。 提交于 2019-12-06 07:29:56
HI all, this one is really simple (I hope). I'm using htmlagility pack to do my webcrawling. So what happens if I input url whatever, that then directs me to a new url, how do I capture that new redirected URL? If htmlagility pack doesnt have a way, can someone suggest another method? When you create your HttpWebRequest you can set AllowAutoRedirect property to true and it will automatically follow any redirects you have. HttpWebRequest myHttpWebRequest = (HttpWebRequest)WebRequest.Create("http://www.contoso.com"); myHttpWebRequest.MaximumAutomaticRedirections=1; myHttpWebRequest
