Await AJAX with HtmlAgilityPack in Xamarin

由 与世无争的帅哥 提交于 2019-12-05 18:50:37
I have a question that seems to have been asked before, but is a bit different. I'm trying to scrape data from this website but the problem is that is seems like it's loaded with AJAX. Because of that my application is unable to find the id's and classes in the HTML that I'm looking for. You can reproduce this by inspecting an element or viewing the source. Whilst viewing the source I'm seeing a lot less than whilst inspecting an element. I thought that I could track down the file that contains the AJAX to load this html by pressing F12, going to the network tab and selecting XHR, but I'm

Replacing tags in HtmlAgility

由 北战南征 提交于 2019-12-05 08:20:59
I'm trying to replace all of my h1 tags with h2 tags and I'm using HtmlAgility pack. I did this: var headers = doc.DocumentNode.SelectNodes("//h1"); if (headers != null) { foreach (HtmlNode item in headers) { //item.Replace?? } } and i got stuck there. I've tried this: var headers = doc.DocumentNode.SelectNodes("//h1"); if (headers != null) { foreach (HtmlNode item in headers) { HtmlNode newNode = new HtmlNode(HtmlNodeType.Element, doc, item.StreamPosition); newNode.InnerHtml = item.InnerHtml; // newNode suppose to set to h2 item.ParentNode.ReplaceChild(newNode, item); } } problem there is

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.

How to use httpRequest and HtmlAgilityPack together?

由 試著忘記壹切 提交于 2019-12-04 20:02:43
So I am trying to log into a page and get some data out of that page, but my problem is filling in these Login information. What have I tried? Posting data in url. By simply adding the postname en the value like so: http://stackoverflow.com?postLogin=myUsername&postPassword=myPassword . I sent a request with this url. It gave me an error. I checked out the url on a browser. It seems that it does fill in the username but not the password textbox(I have written the correct postnames). I also saw someone giving advice to use HtmlAgilityPack to fill in the data(which was marked as answer). But

Getting the text from a node using HtmlAgilityPack

由 喜夏-厌秋 提交于 2019-12-04 18:31:37
I have the following HTML: <div class="top"> <p>Blah.</p> I want <em>this</em> text. </div> What is the XPath notation to extract the string " I want <em>this</em> text. "? EDIT: I don't necessarily want a single XPath expression to extract the string. Selecting multiple nodes, and iterating over them to produce the sentence, would be great as well. HtmlDocument doc = new HtmlDocument(); doc.LoadHtml(myHtml); doc.DocumentNode.SelectSingleNode("??????"); What do you want to extract, nodes or a string? If you want nodes, "I want <em>this</em> text." is an XML fragment consisting at the top level
