</div>


<div>
I guess I should have tested it BEFORE posting :)<br />
<br />
This one actually works..<br />

<pre><code class="code-10 nolinks" id="code-260469"><span>&lt;!--- returns all elements of list one minus the elements of list two ---&gt;</span>
<span>&lt;!--- #listMinus(&quot;1,2,3,3,3,4,5&quot;, &quot;3,5,6&quot;)#  returns 1,2,4 ---&gt;</span>
<span>&lt;cffunction name=&quot;listMinus&quot; access=&quot;public&quot; output=&quot;false&quot;&gt;</span>
<span>   &lt;cfargument name=&quot;listOne&quot;  required=&quot;true&quot; default=&quot;&quot; /&gt;</span>
<span>   &lt;cfargument name=&quot;ListTwo&quot;  required=&quot;false&quot; default=&quot;&quot; /&gt;</span>
<span> </span>
<span>   &lt;cfset var result = &quot;&quot;&gt;</span>
<span>   &lt;cfset var kk = &quot;&quot;&gt;</span>
<span>    </span>
<span>   &lt;cfloop index=&quot;kk&quot; list=&quot;#arguments.listOne#&quot;&gt;</span>
<span>     &lt;cfif listFindNoCase(arguments.listTwo,kk) eq 0&gt;</span>
<span>       &lt;cfset result = listAppend(result,kk)&gt;</span>
<span>     &lt;/cfif&gt;</span>
<span>   &lt;/cfloop&gt;</span>
<span>    </span>
<span>   &lt;cfreturn result&gt;</span>
<span>&lt;/cffunction&gt;</span>
<span> </span>
<span> </span>
<span>&lt;cfoutput&gt;#listMinus(&quot;1,2,3,3,3,4,5&quot;, &quot;3,5,6&quot;)#&lt;/cfoutput&gt;</span>
</code></pre>

Hi,

comparing two lists in coldfusion

ColdFusion is a server-side rapid application development platform originally created by Allaire and now sold by Adobe, implementing the dynamic general purpose CFML programming language. The term ColdFusion is sometimes colloquially used to refer to the CFML language (Cold Fusion Markup Language), but can also include discussions of the server software implementation. ColdFusion runs using a customised version of Apache Tomcat. Earlier versions are bundled with JRun.
