can anyone think of an elegant way of getting the tag-name of a html-tag? currently i have `"&lt;my-tag&gt;...&lt;/my-tag&gt;".removePrefix("&lt;").takeWhile { it != '&gt;' }`

that’ll get you all the attributes in the tag too

plus it’ll get you weird results on doctype statements and cdata sections if you ever run into those

that’s true, but in my case it should always be on this form (2+ words joined by dashes, no attributes)

you could try with a regex
```
val re = Regex("&lt;(\\w+)&gt;") 
re.find("&lt;my-tag&gt;...&lt;/my-tag&gt;")?.groupValues?.get(1)
```
obviously this works on very simple strings containing one tag, a regex can’t parse a full xml document

definitely an important caveat. XML/HTML is not a regular language and cannot be parsed by regular expressions

Oh, Shawn is right… so for this simple case change the regex to `&lt;([-\w]+)`

thanks <@UMJ5ZFW0M>, that’ll do nicely for my case
