Regex match a specific char and don't match another one
<p>I have a file like this one, I want to match some of the strings:</p>

<pre><code>https://site.me/ //matches
https://site.me// //does not match (there is a slash)
https://site.me/deck //does not match (there is not a dot)
https://site.me/hello.php //matches (there is a dot and zero slashes)
https://site.me/deck/hello.php //does not match (there is a slash)
</code></pre>

<p>The pattern should be: <code>https://site.me/</code> followed by any slash does not match. Followed by a dot and not a slash matches. Followed by any chars with no dots does not match.</p>

<p>Here is <a href="http://regexr.com/3ci2n" rel="nofollow">my try</a>:</p>

<pre><code>https://site.me/((?!/).)*$
</code></pre>
