Issue with building an array from a cfhttp request result.

Question

Here is what I am trying to do. Retrieve a bunch of results from a  REST request. Run a query to see if I should be excluding any of the xmltext entries coming back from the rest request. Build an array of the REST xmltext entries except the entries in the cfquery.
I have it all workign except building the array minus the entries that came back in the cfquery. Here is my code so far.
<cfquery name="getqueue" datasource="#application.settings.dsn#">
select * from friends
where Deactivatedate < #DATEADD('d', 1, CreateODBCDateTime(now()))#
</cfquery>
<cfoutput query = "getqueue">
<cfhttp  blah blah>
<cfset nodes_parse = XmlParse(CFHTTP.FileContent)>
<cfset Nodes = xmlSearch(nodes_parse,'friends/friend/date/activedate/')>
<cfset roleArray = ArrayNew(1)>
<cfloop from="1" to="#arraylen(Nodes)#" index="i">
   <cfset NodeXML = xmlparse(Nodes[i])>
<cfset ArrayAppend(roleArray, '[sel_members][]=#NodeXML.activedate.xmlText#&')>
</cfloop>
</cfoutput>
My issue is down in the loop where I do the arrayappend. How would I build an array of values coming back from the cfhttp request but not include any of them if they match up with anything coming back from the getqueue query?

What about the obvious? Namely,
<cfif value_from_getqueue IS NOT value_from_cfhttp_request>
<cfset arrayAppend()>
</cfif>
