Extracting the text of a html / css code in c#

Question

is it possible, to get the text relevant part of a formated html/css code? I got this content:

<div class="ExternalClass0909250B34584AE5AA58772B3064DCD5">
    <p style="margin&#58;0in;font-family&#58;calibri;font-size&#58;11pt;">Solution (SO_)= lml</p>
    <p style="margin&#58;0in;font-family&#58;calibri;font-size&#58;11pt;">Product (PR_)= slider</p>
    <p style="margin&#58;0in;font-family&#58;calibri;font-size&#58;11pt;">Team (T_) = kehrberger</p>
    <p style="margin&#58;0in;font-family&#58;calibri;font-size&#58;11pt;">&#160;</p>
    <p style="margin&#58;0in;font-family&#58;calibri;font-size&#58;11pt;">Anforderer = renner</p>
    <p style="margin&#58;0in;font-family&#58;calibri;font-size&#58;11pt;">&#160;</p>
    <p style="margin&#58;0in;font-family&#58;calibri;font-size&#58;11pt;">Erfolgt ein FAK – Einsatz? Nein&#160; </p>
    <p style="margin&#58;0in;font-family&#58;calibri;font-size&#58;11pt;">Werksvertrag </p>
    <p style="margin&#58;0in;font-family&#58;calibri;font-size&#58;11pt;">Beistellung relevant?&#160; nein</p>
    <p style="margin&#58;0in;font-family&#58;calibri;font-size&#58;11pt;">&#160;</p>
    <p style="margin&#58;0in;font-family&#58;calibri;font-size&#58;11pt;">Anlieferadresse&#58;</p>
    <p style="margin&#58;0in;color&#58;black;font-family&#58;arial;font-size&#58;10pt;">Bürocampus Wangen - Kofi Warenannahme</p>

    <p style="margin&#58;0in;color&#58;black;font-family&#58;arial;font-size&#58;10pt;">70327 Stuttgart</p>
</div>

When I just inserte this in the text window here, he displays this:

<div class="ExternalClass0909250B34584AE5AA58772B3064DCD5">

Is it possible in C# to get just the text as shown in the yellow box?

Thank you.

Just about anything is possible. Have you looked into libraries that understand HTML and tries to use them? What was the result of that? — mason, Aug 11 '17 at 17:58
You could also try using an XML parser. .NET has a few built in. — Adam Schiavone, Aug 11 '17 at 18:00
@AdamSchiavone [HTML is not XML](https://stackoverflow.com/questions/5558502/is-html5-valid-xml). — mason, Aug 11 '17 at 18:01
@mason You're absolutely correct. However, the example he gives is valid XHMTL. But yeah in general you need a parser that can handle the quirks of HTML. — Adam Schiavone, Aug 11 '17 at 18:06

A quick Google search for "C# HTML Parser" yielded at least these two resources:

The HTML Agility Pack
AngleSharp

Please read the documentation, and come back here if you have specific errors you need help dealing with.

I'd use the Html Agility pack. Add it through Nuget. Once you have that you can do something like below

HtmlDocument doc = new HtmlDocument();
doc.LoadHtml(yourHtml);
HtmlNode myNode = doc.DocumentNode.FindNode(some xpath to select what you want);

now you can extract the text from myNode, children/parentnodes, or any of the attributes such as the styles, etc.

Yes, I found this answer very often. But I doesn't work in my case. – Jan021981 Aug 11 '17 at 18:06
System.Windows.Forms.HtmlDocument MyDocument = new System.Windows.Forms.HtmlDocument() //ERROR: HtmlDocument doesn't contain a constructor that takes 0 arguments – Jan021981 Aug 11 '17 at 18:07
And the method "LoadHtml" is also not available. – Jan021981 Aug 11 '17 at 18:07
Ahhh, ok. Sorry. This is not the HtmlDocument of the namespace System.Windows.Forms.... – Jan021981 Aug 11 '17 at 18:09
sorry yes, you'll have to add "using HtmlAgilityPack;" – chris-crush-code Aug 11 '17 at 19:09

Its not actively maintained anymore, but you could try using CsQuery.

I've had some luck with it in the past, doing similar things.

Thank you very much - it was a missunderstanding. In the most examples in the wwww, the used the HtmlDocument-Class. Such a Class is provided in the Lib System.Windows.Forms. The examples used the Lib "HtmlAgilityPack" where the class has the same name.

My problem is solved - thank you all.
