如何删除<h1>来自 html 字符串 java 的标签</h1>

Question

I have a string我有一个字符串

String mystring = "<html><head><meta name="viewport" content="width=device-width"></head><body><h1><a href="q://d?EN&hello">hello</a></h1>
<p>
<h3>Alternative forms</h3>
<ul><li> <a href="q://d?&hallo">hallo</a></li>
<li> <a href="q://d?&hilloa">hilloa</a> (obsolete)</li>
<li> <a href="q://d?&hullo">hullo</a> (UK)</li>
</ul>

<h3>Etymology</h3>
<a href="q://d?&Hello">hello</a> (first attested in 1833), from <a href="q://d?&holla">holla</a>, <a href="q://d?&hollo">hollo</a> (attested 1588). This variant of <a href="q://d?&hallo">hallo</a> is often credited to Thomas Edison as a coinage for telephone use, but its appearance in print predates the invention of the telephone by several decades.Ultimately from a variant of Old English <em><a href="q://d?&eala">&#x113;al&#x101;</a></em>, such as <em><a href="q://d?&hela">h&#x113;l&#x101;</a></em>, which was used colloquially in that time similarly to how &quot;hey&quot; or &quot;hi&quot; is used nowadays. Thus, equivalent to a compound of <em><a href="q://d?&hey">hey</a></em> and <em><a href="q://d?&lo">lo</a></em>.Possibly influenced by the lang:goh and lang:osx verb <a href="q://d?&halon">halon</a>, <a href="q://d?&holon">holon</a> (&quot;to bring something, to gather&quot;), akin to English <a href="q://d?&hale">hale</a> or <a href="q://d?&hail">hail</a>.
