Dopo aver rimosso RTF non era troppo difficile analizzare il file e trasformarlo in un CSV. I miei file analizzati risultanti che contengono tutti i codici ICD-9 2009 per Malattie e Procedure sono qui: http://www.jacotay.com/files/Disease_and_ProcedureCodes_Parsed.zip Il mio parser che ho scritto è qui: http://www.jacotay.com/files/RTFApp.zip Fondamentalmente si tratta di un processo in due fasi: prelevare i file dal sito FTP CDC e rimuovere il RTF da loro, quindi selezionare i file RTF-free e analizzarli nei file CSV. Il codice qui è piuttosto approssimativo perché avevo solo bisogno di ottenere i risultati una volta.
ecco il codice per l'applicazione di analisi nel caso in cui i collegamenti esterni si abbassano (back-end a una forma che consente di selezionare un nome di file e fare clic sui pulsanti per farlo andare)
