I would probably start by defaulting all those structure variables to empty
strings, i.e.
<cfset requiredfields =
"assetid,title,description,version,statusid,keywords,formatid,location">
<cfloop index="x" list="#requiredfields#">
<cfparam name="request.datastruct.#x#"
type="string" default="">
<cfloop>
Then you can just use len(trim(key)) to determine if a given key is filled
in... something like this might simplify it and make management easier:
<cftry>
<cfloop index="x" list="#requiredfields#">
<cfif not len(trim(request.datastruct[x]))>
<cfthrow type="requiredfield" message="#x#"></cfif>
</cfloop>
<p><a href="writefile.cfm">Download Your XML File.</a></p>
<cfcatch type="requiredfield"></cfcatch>
</cftry>
