It can’t be done, as an opening tag in html can contain anything in its attributes, even JavaScript (e.g. onclick handler).

You can’t parse every html opening tag with regex, because a html opening tag doesn’t have a set structure. How would you match, with regex, this opening tag?
<mytag myattribute="<value of \"myattribute\">" >

Is this valid HTML? My understanding is that that attribute value needs to be escaped, i.e. <value of \"myattribute\">.
