Remove HTML tags from a String

If you're writing for Android you can do this...

androidx.core.text.HtmlCompat.fromHtml(instruction,HtmlCompat.FROM_HTML_MODE_LEGACY).toString()

Use a HTML parser instead of regex. This is dead simple with Jsoup.

public static String html2text(String html) {
    return Jsoup.parse(html).text();
}

Jsoup also supports removing HTML tags against a customizable whitelist, which is very useful if you want to allow only e.g. <b>, <i> and <u>.
