i have wrote simple csv upload function angular-file-upload. code following. think need access content of file upload. need first several rows of csv show preview of file. know how data?

  app.controller('reporting.importexternaldata.controllers.main', [             '$scope',         'fileuploader',         function ($scope, fileuploader) {             console.log('hahahahahaah');              var uploader = $scope.uploader = new fileuploader({                 autoupload: false,                 queuelimit: 1,                 filters: [{                     name: 'csvonly',                     fn: function(item) {                         console.log('in filter, file type (item.type) is: ' + item.type);                         console.info('size: ' + item.size);                         return true;                     }                 }]             });        } ]);

html:

<div>         <h2> choose csv file </h2>         <input type="file" nv-file-select="" uploader="uploader" accept=".csv" />     </div>     <p>queue length: {{ uploader.queue.length }}</p>     <div ng-repeat="item in uploader.queue">         <h2>{{ item.file.name }}</h2>         <p>{{ item._file}}</p>     </div>

in <p>{{ item._file}}</p>, expect have preview of first 5 rows of csv. not know how access data, know how?
