arrays - Looping Through a ColdFusion Structure

Question

Can someone help me loop through a structure.

<cfset resData2 = ConvertXmlToStruct(gatewayResponse.Filecontent, StructNew())>
<cfset resTran2 = 'resData2.Body.PosResponse.Ver1.0.Transaction.ReportBatchDetail.Details'> 
<cfloop index="idx2" from="1" to=#StructCount(resTran2)# step="1"> 
    <cfdump var="#resTran2#">
</cfloop>

Here is the structure:

Answer 1

A few issues with your code. As @Miguel-F pointed out, your assignment to restran2 should not be enclosed in quotes because you're making the assignment into a literal string. Secondly, your result going into resTran2 is an array of structs, so what you want to use for your upper loop limit is ArrayLen() and not StructCount(). Lastly, because one of your keys Ver1.0 contains a period in it, you will need to use bracket notation instead of dot notation to reference it.

<cfset resData2 = ConvertXmlToStruct(gatewayResponse.Filecontent, StructNew())>
<cfset resTran2 = resData2["Body"]["PosResponse"]["Ver1.0"]["Transaction"]["ReportBatchDetail"]["Details"]> 
<cfloop index="idx2" from="1" to="#ArrayLen(resTran2)#" step="1"> 
    <cfset batchID = resTran2["batchID"][idx2]>
    <cfset batchSeqNbr = resTran2["batchSeqNbr"][idx2]>
    ....
</cfloop>
