Sibling elements under parent array

[ruckus]

Not sure if the title is accurate :( I'm trying to generate XML like:

    <EstimateQueryRq iterator="Start">
      <MaxReturned>50</MaxReturned>
      <EntityFilter>
        <ListID>80000042-1424746827</ListID>
        <ListID>8000001B-1407979267</ListID>
      </EntityFilter>
      <IncludeLineItems>true</IncludeLineItems>
      <OwnerID>0</OwnerID>
    </EstimateQueryRq>

My hash is:

{
   "max_returned"=>50, 
   "xml_attributes"=>{"iterator"=>"Start"},
    "EntityFilter"=>[{"list_id"=>"80000042-1424746827"}, {"list_id"=>"8000001B-1407979267"}],    
    "include_line_items"=>true, 
    "OwnerID"=>0
}

So EntityFilter is an array of two elements.

But the library is actually producing this XML:

    <EstimateQueryRq iterator="Start">
      <MaxReturned>50</MaxReturned>
      <EntityFilter>
        <ListID>80000042-1424746827</ListID>
      </EntityFilter>
      <EntityFilter>
        <ListID>8000001B-1407979267</ListID>
      </EntityFilter>
      <IncludeLineItems>true</IncludeLineItems>
      <OwnerID>0</OwnerID>
    </EstimateQueryRq>

Notice the duplication of the EntityFilter element.

Do I need to restructure my hash? Any guidance would be appreciated.

Thanks!

Answered my own question. Yes, the hash needs to be restructured like:

{
   "max_returned"=>50, 
   "xml_attributes"=>{"iterator"=>"Start"}, 
    "EntityFilter"=>{
          "list_id"=>["80000042-1424746827", "8000001B-1407979267"]
    }, 
   "include_line_items"=>true, 
   "OwnerID"=>0
}
