✅ Remove tags from string

So if I have a string like this This is a string with <color="red">different colors</color>. And some cool <shake>other effects</shake> How can I remove the tags from the string and leave the rest as is? I was thinking of looking into the string and removing everything between < and > but I can't seem to find a solution that would do that. Any suggestions?

if you can use regex it's pretty easy. Regex.Replace(inputString, "<.*?>", "");

oooh I wasn't aware regex was in c# that's nice I'll try that. Thanks

Pretty much every language has some sort of regex support But... what if the string is <foo>two < three</foo>? What if it's <foo>a -> b -> c</foo>?

True. Might be situations where it's desired to have those within. But I think for now I can live without. I guess the string would need to have some escape string type deal.

One of the reasons you never really sanitize for HTML nowadays, you just escape it Instead of stripping all <script>s and the like, you just display it as <script>

I'm not sanitizing html 😄 Doing an dialog system that has text styling tags in it

You're looking at making some parser, then Or using something existing like BBCode

Sorry, should've added that in the question. a custom parser yeah

Ah, well, you should tokenize it then, into something like

[
  {str: "This is a string with "},
  {str: "different colors", color: Colors.Red},
  {str: ". And some cool"},
  {str: "other effects", effect: new Shake()}
]

[
  {str: "This is a string with "},
  {str: "different colors", color: Colors.Red},
  {str: ". And some cool"},
  {str: "other effects", effect: new Shake()}
]

If you do that, no need to strip anything And with a parser like this you already keep track of <s and >s, so it should be easy to tell which strings are not parts of the tags at that stage

True, I might actually do that. Because the more I think of it the more confusing it gets. Yeah, I'll have to take a closer look at that. To be honest this has now made me rethink my entire system so I might just re do it. Thanks for the advice everyone.
