title: Coldfusion - Remove all non-numeric values from a list?
body: <p>I have a list of IDs being passed through the URL. I want to do some sanitizing before running a query based on those IDs. I have this:</p>
  
  <pre><code>&lt;cfset URL.ID = ReReplaceNoCase(URL.ID,"[^0-9]","","ALL")&gt;
  </code></pre>
  
  <p>But I realize that's stripping the comma out also. Is there a simple way to remove non numeric values from a list in Coldfusion?</p>
