Regex extract number from a string with a specific pattern in Alteryx : <p>I have string like this which looks like a url</p>

<pre><code>mainpath/path2/abc/PI 6/j
</code></pre>

<p>From the string I need to get the number along with <strong>PI</strong></p>

<p>Main problem is the position of <strong>PI</strong> part wont be always the same. Sometimes it could be at the end. Sometimes at the middle.</p>

<p>So how can I get that number extracted using regex?
I'm really stucked with this</p>
