kandi X-RAY | AngleSharp Summary
AngleSharp is a .NET library that gives you the ability to parse angle bracket based hyper-texts like HTML, SVG, and MathML. XML without validation is also supported by the library. An important aspect of AngleSharp is that CSS can also be parsed. The included parser is built upon the official W3C specification. This produces a perfectly portable HTML5 DOM representation of the given source code and ensures compatibility with results in evergreen browsers. Also standard DOM features such as querySelector or querySelectorAll work for tree traversal.

I have made myself a simple .NET console app in C# to scrape a dynamic page for personal use using Selenium C#.
The selenium navigation works perfectly fine, but when I am about to resolve the resulting page source and retrieve a list of real estate addresses, it returns null. And on top of that, it also gives warning and errors relating to chrome browser.

I simply needed to add a wait timer after Selenium submitted the search query, such as
Thread.Sleep(3000), to let the page to fully load before parsing the HTML.
When I use AngleSharp in VB.NET, the lambda in C# becomes a question. VB.NET can use

There are two problems with your code:
The overload that you're trying to use takes an
Action, not a
Func. Therefore, you ought to use
In VB, the dot has to come at the end of the line, not at the beginning of the next one (in C#, you may do either), or else the line continuation character (i.e.,
_) must be used.
Changing your code to something like the following should make it compile:

The beauty of AngleSharp is that you can essentially fall back to any JS solution - as AngleSharp exposes the W3C DOM API (which is also used by JS). All you'd need to do is replace certain camelCase with PascalCase and use standard .NET tools instead of things from JS.
The project is a C# desktop application that interacts with a webpage.
The last time I did anything like this, I used WatiN and HTMLAgilityPack. But WatiN isn't very elegant as it opens a browser window to interact with the website. It's more designed for Integration Testing, still it got the job done.
This time I'm looking at AngleSharp to parse the HTML, but I still need to write code that logs into the website, presses a couple of buttons and does some POSTS.
Are there any frameworks I can use to make this straightforward?...

I'm trying to get css @page rules from an AngleSharp parsed html file. It's interesting because I can get the Rules property when I am debugging the stylesheet but not when I try accessing it when writing code. Am I missing a nuget package?...

I'm trying to update a site that uses an sanitizer based on AngleSharp to process user-generated HTML content. The site users need to be able to embed iframes, and I am trying to use a whitelist to control what domains the frame can load. I'd like to rewrite the 'blocked' iframes to a new custom element "blocked-iframe" that will then be stripped out by the sanitizer, so we can review if other domains need to be added to the whitelist.

Yes this is possible.
I have a requirement where I need to strip all tags out of a large block of HTML that is tag-soup, essentially stuff like:
I need to strip them all out, except the
tags, but on those I need to strip out the attributes such as
style="" and just leave them as
I am currently stripping all tags with a regex:
public static string StripHtml(string input) => Regex.Replace(input, "<.*?>", string.Empty)
Any ideas on how to do this?
I would use a customized C# library for this but I am using .Net Core on Linux so a lot of these libraries (such as AngleSharp) that require the full framework aren't going to work for me....
ANSWERAnswered 2020-Feb-09 at 14:30
<((?!p\s).)*?> will give you all tags except the paragraphs. So your program could delete all matches of this regex and replace the rest of the tags (all p's) with empty paragraph tags. (
regex for receiving all p-tags)
