title: Regex Find and Replace in Pine Script
body: <p>Can someone give an example of how to use the <a href="https://www.tradingview.com/blog/en/find-and-replace-in-pine-editor-18848/" rel="nofollow noreferrer">Find and Replace using Regex</a> feature in Pine? I'd like to use regex to find all text with numbers in the middle and end like:</p>
  <pre><code>abc_1_xyz10
  abc_1_xyz11
  abc_1_xyz12
  abc_2_xyz10
  abc_2_xyz11
  abc_2_xyz12
  </code></pre>
