match only HTML name regex

Question

I have this example :

<button type="sasasasasa" abcd="dsqdsq" efgh="sasasa">

I only want to match "button" "type" "abcd" and "efgh".

I already tried : [a-zA-Z:_][a-zA-Z:_.*]* but it matches also what's inside the quotes ""

I thought about taking either "=" or "<" or " " at the beginning to only match but I don't want to have such caracters in my results.

Use an HTML parser _if you can_ because [Regex is not a good tool for matching HTML tags](https://stackoverflow.com/a/590789/4934172). — 41686d6564 stands w. Palestine, Sep 29 '18 at 16:00

You can try this

(?<=<|\s)[a-zA-Z:_][a-zA-Z:_.*][^=|\s]+

This will look after "<" or " " and before "=" or " " but will not include any of the characters.

Check this regex online tester.

Hope this helps

Use this:

(?<= |<)[a-zA-Z]*(?==| )

How it works:

[a-zA-Z]*: search for any sequence of letters which ...
(?<= |<): is preceded by either a < (as in the case of button) or by a space and ...
(?==| ): is followed by either a = sign or a space (as in the case of button)
