问题 I use htmlagility to get webpage data but I tried everything with page using www.cloudflare.com protection for ddos. The redirect page is not possible to handle in htmlagility because they don't redirect with meta nor js I guess, they check if you have already being checked with a cookie that I failed to simulate with c#.

问题 I'm trying to login to a site using HtmlAgilityPack (site:http://html-agility-pack.net). Now, I can't exactly figure out how to go about this. I've tried setting the Html form values via m_HtmlDoc.DocumentNode.SelectSingleNode("//input[@name='EMAIL']").SetAttributeValue("value", "myemail.com"); I then submit the form with m_HtmlWeb.Load("http://example.com/", "POST"); This isn't working though. It's not logging in or anything. Does anyone else have any other insight? Thank you 回答1: The HTML

Select only items in a specific DIV using HtmlAgilityPack

问题 I'm trying to use the HtmlAgilityPack to pull all of the links from a page that are contained within a div declared as <div class='content'> However, when I use the code below I simply get ALL links on the entire page. This doesn't really make sense to me since I am calling SelectNodes from the sub-node I selected earlier (which when viewed in the debugger only shows the HTML from that specific div). So, it's like it's going back to the very root node every time I call SelectNodes. The code I

Selecting attribute values with html Agility Pack

I'm trying to retrieve a specific image from a html document, using html agility pack and this xpath: //div[@id='topslot']/a/img/@src As far as I can see, it finds the src-attribute, but it returns the img-tag. Why is that? I would expect the InnerHtml/InnerText or something to be set, but both are empty strings. OuterHtml is set to the complete img-tag. Are there any documentation for Html Agility Pack? Html Agility Pack does not support attribute selection. Pierluc SS You can directly grab the attribute if you use the HtmlNavigator instead. //Load document from some html string HtmlDocument

How to get html elements with multiple css classes

由 大憨熊 提交于 2019-11-26 22:12:55
I know how to get a list of DIVs of the same css class e.g <div class="class1">1</div> <div class="class1">2</div> using xpath //div[@class='class1'] But how if a div have multiple classes, e.g <div class="class1 class2">1</div> What will the xpath like then? The expression you're looking for is: //div[contains(@class, 'class1') and contains(@class, 'class2')] I highly suggest XPath visualizer, which can help you debug xpath expressions easily. It can be found here: http://xpathvisualizer.codeplex.com/ i think this the expression you're looking for is //div[starts-with(@class, "class1")]/text(
