   usage:   Used to list the IPEDS data files tagged in ipedsFiles.xml as containing directory data.
            Run the XQuery program from the path where it is located.
   example: zorba -e xml_ipedsFiles:="../xml/metadata/ipedsFiles.xml" -f -q list_directory_files.xq -z indent=yes

declare variable $xml_ipedsFiles external;

<results>
{
for $i in fn:doc($xml_ipedsFiles)/ipedsFiles/file[@dir_ind="1"]
let $name := $i/@ipedsName,
    $title := $i/@title,
    $dir := $i/@dir_ind,
    $year := $i/@year
order by $year descending
return
    <file year="{$year}" name="{$name}" title="{$title}" directory="{$dir}" />
}
