Issue with building an array from a cfhttp request result.

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?
