ColdFusion Structure

Question

I'm looping an array of records (from a fixed length feed)
and creating a structure for each required field. Then for every
loop, I'm passing this structure to a function to check if certain
required field in the structure's element is left empty.
The structure should look something like this:
<cfloop from="1" to="#ArrayLen(MyFile)#" index="i">
<cfset aEachLine
=StructNew()>
<cfset aEachLine["LastName"]="#Mid(MyFile
,17,40)#">
<cfset aEachLine["FirstName"]="#Mid(MyFile
,57,20)#">
<cfset aEachLine["Address"]="#Mid(MyFile
,140,38)#">
<cfset aEachLine["City"]="#Mid(MyFile
,254,19)#">
<cfset aEachLine["State"]="#Mid(MyFile
,273,2)#">
<cfset aEachLine["Country"]="#Mid(MyFile
,284,4)#">
In this example I'm assuming that my structure is this short
<CFSET CheckStructValue=CheckThisStruc(aEachLine)>
</cfloop>
How do I check if any of those struct. value is
empty?

alecken,
I don't think looping is the only way but suggested this
approach because, I think, you can more easily write code that
determines which key in a struct is empty (if any) and then report
back to the user the issue (or do something else such as inserting
default values, etc.).
That said, since the purpose of StructFindValue is to locate
any key that has the value supplied, it should work. I just wrote
and tested the following code and it worked:
<cfscript>
myStruct = StructNew();
myStruct.key1 = "Key 1 Value";
myStruct.key2 = "Key 2 Value";
myStruct.key3 = "";
myFind = StructFindValue(myStruct,"");
</cfscript>
<cfdump var="#myFind#">
The resulting output of an array of structures showed me that
key 3 was empty.
While this works to locate empty keys, I would still need to
write code that determines which key was empty and then what to do
from there. I just find it easier to loop over the struct and act
accordingly on each key it finds that is empty as it loops over the
struct. But that's just me!
There are some structure functions on cflib.org that might
help but in a cursory look over the site, I did not see anything
off hand.
