![]() A real browser like Chrome is capable of executing any client code present on the page thus generating all the dynamic content. This works because we will be using an actual browser to retrieve the HTML page. If we need to parse dynamically rendered HTML content we can use a browser automation tool like Selenium WebDriver. NET/C# content and get paid? > JOIN US! << This may be a problem when we try to parse HTML from a remote website, causing the content to be unavailable to our program since the client code hasn’t been executed. Often, websites use client code like javascript to render HTML elements dynamically. Parsing HTML From a Browser Using Selenium In this case, we are selecting the title tag inside the head section of the document. Once we parse the content by calling the Load() method of the HtmlWeb instance with the site’s URL, we can use the methods we already know to access the content. NET and Web Development Tutorials", node.InnerHtml) Var node = ("//head/title") Īssert.Equal("Code Maze - C#. To parse content straight from a URL, we need to use an instance of the HtmlWeb class instead of HtmlDocument: var url = web = new HtmlWeb() Let’s say our goal is to get HTML from a public website. In this case, we are retrieving the second-level header text via the InnerHtml of the h2 tag in the document. Once loaded, we can query the document contents by using DocumentNode.SelectSingleNode() method. Var htmlHeader = ("//h2") Īssert.Equal("HTML Agility Pack", htmlHeader.InnerHtml) Then, we can instantiate a new HtmlDocument object and use its Load() method to parse the content of our HTML file: var path = doc = new HtmlDocument() HTML Agility Pack is a popular web scraping tool. To demonstrate that, let’s first create an HTML file and save it with the name test.html: We can easily load HTML from files located on a local hard drive. While parsing HTML documents from strings is simple, sometimes we will need to obtain our HTML from other sources. And, finally, we access the text content of the h1 tag through the InnerHtml property. We use SelectSingleNode() on it to query the document model searching for the h1 tag inside the document. The HtmlDocument object exposes a DocumentNode property that represents the root tag of the snippet. Here, we parse a string containing some basic HTML to get an HtmlDocument object. Var documentHeader = ("//h1") Īssert.Equal("Learn To Code in C#", documentHeader.InnerHtml) don't forget to wrap this JS code to be executed only in normal mode.Once done, we can easily parse an HTML string: var html = To Code in C# The last character of the truncated text. * Don't add an ellipsis if this array contains * Remove these characters from the end of the truncated text. Where(n => n.NodeType = HtmlNodeType.Text & n.InnerText.Trim().Length > 0) Get text nodes with the appropriate running total Please be aware that it's not my code and all the credits go to Serge Belov public string TrimRichText(string input, int maxLength) Mark commented that this is a link only answer, so I'll copy the code from the linked SO question. See here for details: HtmlAgilityPack substring of all by length It's already there with your Sitecore site.
