It handles tables too, but once they're collapsed adjacent columns are stuck together with no spaces which can be confusing.īreaking from the voyeuristic norms of the Internet, any comments can be made in private by contacting me.- Support `\line` as line-break control character when reading RTF Formatting such as paragraphs are preserved. You can then simply call .ConvertToText() and receive a text view of your HTML. You will also need to reference C:/Program Files (x86)/Reference Assemblies/Microsoft/Framework/.NETCore/v4.5/. You will then be able to add a reference to the "Windows" assembly in a new tab on the Add References dialogue. You have to edit your *.csproj (or whatever proj) file in a text pad and add in the line 8.0 into the top/main ProjectGroup node. This blog by Andrei Marukovich covers how. Ideal, apart from it's a part of the WinRT API - geared for Windows Store apps, and not desktop (or server) applications.įortunately, whilst the WinRT API is for Windows Store, Microsoft does support it with desktop applications, you just have to go through a few hoops to get there. Which, "parses the HTML-formatted data, no scripts are run and no secondary downloads occur". And that is to use the HtmlUtilities.ConvertToText() method. My solution to the problem is slightly different and has its own draw-backs. But for bulk conversion of text? That's tricky as whilst you can get your "//text()" nodes, you have to reassemble them into something useful. This are other similar libraries for other languages/frameworks, and they all work great for targeting specific bits of data on a web-page etc. NET and will load up badly formed HTML and deal with non-XHTML syntax. It's more forgiving than the XML parser in. This is a handy library that allows you to use HTML documents in the same way as you would XmlDocument. The remaining popular solution is the Html Agility Pack. I don't really fancy having a server process doing that on anything that can be emailed in. The second more critical hurdle is that Trident is a browser engine (not one known for security either), and it will download all content linked to in the page, and run any Javascript. The first hurdle is you're having to interop with COM - which is made easier with Primary Interop Assemblies but still a little messy to develop and more importantly, distribute. This will render the document and you should be able to access that output (without actually spawning IE). The first more "out-of-the-box" solution is to harness mshtml.dll - Internet Explorer's Trident engine. There are some libraries out there that do this for various languages. The next solution would be to parse the HTML (or SGML) and have your system understand it. ![]() At the basic level, simple paragraphs are defined as a tag in HTML, if you're lucky, there will be a carriage return in the text along with it to match, but there is no reason why this would be. ![]() Even if you filter out all the gumph, and deal with decoding
