AngleSharp.Demos.Indotnet

Simple and sweet demonstration playground for AngleSharp as shown in the Indotnet usergroup on November 2016.

If you have anything to add to the demo, then feel free to do so. Push requests are always highly appreciated.

Companion Slides

The slides for the talk can be found at talks.florian-rappl.de/AngleSharp-Indotnet/. They are rather sparse and do not provide the full information spread during the talk.

Running the Sample

The demo is a Visual Studio 2015 solution that uses C# 6 together with the AngleSharp library. For demonstration purposes also the AngleSharp.Scripting.JavaScript library has been loaded.

The application is a WPF UI that uses the MVVM pattern. The main viewmodel is the MainViewModel. Here the connection to the transformation is designed. The ParseAsync method is called when the source code (via the Source property) changes.

Generally, the code is quite similar to the demo for the Munich.NET usergroup, however, this one does not include any CSS parts and focuses on a live preview.

Playing around with the Sample

The thing that can be done is typing in elemental parts of any HTML document such as <!doctype html>. Seeing it being interpreted in real time (e.g., first as a text, then a comment, finally the doctype) is wonderful - educational and working-wise. Also complex examples can be shown in no time; how HTML5 treats nested tables or complicated formatting.

The scoping rules (applied to paragraphs <p> or list items <li> for example) can also be demonstrated easily. Plus we get some immediate grasp on topics such as raw text (title element) or the <plaintext> tag (there is no way out!).

Another thing is that a JavaScript engine has been integrated. Thus parsing the following chunk of HTML code actually does something:

<script>console.log('Hi Mum!')</script>

The debug output view of Visual Studio should display "Hi Mum!". This can be abused as such:

<script>document.write('<span>again</span>')</script>

Inserting this and pressing "Transform!" multiple types will repeat the again in the span element. This is a nice way to "grow" a document. Granted, a rather boring document.
