can anyone think of an elegant way of getting the tag-name of a html-tag? currently i have

"<my-tag>...</my-tag>".removePrefix("<").takeWhile { it != '>' }

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

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("<(\\w+)>") 
re.find("<my-tag>...</my-tag>")?.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

<([-\w]+)

thanks @Matteo Mirk, that’ll do nicely for my case
