&lt;p&gt;One of my biggest pet peeves going back to the original Appian Forums is how frequently everyone jumps at the chance to suggest &amp;quot;REGEX!&amp;quot; despite the fact that there&amp;#39;s almost always a far more simple and lightweight (and possibly faster) out of the box Appian function that does the exact same thing without having to download and then learn the regex plugin.&amp;nbsp; The chances that you can do it without even needing regex are pretty high.&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: Regex Expression</title><link>https://community.appian.com/thread/81570?ContentTypeID=1</link><pubDate>Wed, 12 May 2021 11:17:09 GMT</pubDate><guid isPermaLink="false">d3a83456-d57b-489c-a84c-4e8267bb592a:23de39a5-f9c4-4adb-9203-9629110b11c4</guid><dc:creator>Stefan Helzle</dc:creator><description>&lt;p&gt;Regex function are a plugin you would need to deploy first.
