Using the HtmlAgilityPack to parse HTML in ASP.NET

30 April 2015 13:26

HTML General HTML5

Hardly a week goes by without someone asking a question in the ASP.NET forums about parsing HTML for one purpose or another. Mostly, the questions are couched in terms of 'finding values' or similar, prompting responses from the community that recommend one regular expression pattern or another, treating HTML as a string of text with no structure or rules. In fact, HTML is a structured document format with a set of very clearly defined rules, which means that it can easily be parsed given the right tool. My favourite tool for parsing HTML is the HtmlAgilityPack.

Sessions in ASP.NET Core

ASP.NET MVC ASP.NET 5 ASP.NET Core

ASP.NET Core is being designed so that your application is only dependent on features that it actually needs. This is achieved in large part by creating a composable framework, where the developer opts in to non-essential features - a number of which are baked in to traditional versions of ASP.NET. One of the features that this applies to is Session State. This article looks at how to obtain and use session state in ASP.NET Core applications.
