URL Parsing in Kotlin using Regex
<p>How do I match secret_code_data in string:</p>

<pre><code>xeno://soundcloud/?code=secret_code_data#
</code></pre>

<p>I've tried</p>

<pre><code>val regex = Regex("""xeno://soundcloud/?code=(.*?)#""")
field = regex.find(url)?.value ?: ""
</code></pre>

<p>without luck. I suspect ? before code might be the problem, should I escape it somehow. Can you help?</p>
