Struggling with regular expression <p>I'm struggling to find the regular expression I can use to classify data that matches a certain pattern:</p> <p>Here's a few examples:</p> <pre><code>pli:06e9b616-5712-d0e9-1bc2-000012e61393 pli:6fdd187d-cbdc-3028-4a8d-000020f3449a pli:0472def9-ccf3-e4e9-ca05-00005fecf9f8 </code></pre> <p>As you can see each string begins with pli: and they all have the same pattern even though the characters are different. Each set of characters is separated by a '-' at the same position.</p>
