Extraction target site: [login to view URL] detail: 1. go to [login to view URL] 2. fill estado: adjudicado 3. fill fecha desde: starting date in the format dd-mm-yyyy 4. fill fecha hasta: ending date in the format dd-mm-yyyy 5. fill tipo de compra: Compra menor entre 3000 y 30000 6. click on buscar 7. wait till the results appear 8. open all the links of the column Numero 9. scrap data (based on table especificaciones tecnicas, plus other relevant data): - R - Codigo - Clasificacion - Cantidad - U. Medida - Descripcion - Numero - Descripcion - entidad - dependencia - tipo de procedimiento - fecha de publicacion - precio referencia - nombre -telefono - correo electronico 11. if shows errors loading the page or dont display data, reload or refresh page or mark as error and try later 12. click on the next button of the results page. 13. if clicking on the next button shows any kind of error, wait 5 secs,go back and click on the next again 14. repeat until the end limitations - I need to scrap the data of one complete year 2016. but the server has a limitation that only shows data for the first 50 pages. The best way to do it is to setting a scrapping range of 12 days, so, for example in the first set the starting date 01-01-2016, ending date 12-01-2016. In the next run from 13-01-2016 to 24-01-2016 and go on. so, with this in mind, the script should looks like: 1. create var starting date to 01.01.2016 2. create var ending date to 12.01.2016 3. start a loop 4. go to [login to view URL] 5. fill estado: adjudicado 6. fill fecha desde: starting date in the format dd-mm-yyyy 7. fill fecha hasta: ending date in the format dd-mm-yyyy 8. fill tipo de compra: Compra menor entre 3000 y 30000 9. click on buscar 10. wait till the results appear 11. open all the links of the column Numero 12. scrap data (based on table especificaciones tecnicas, plus other relevant data): - R - Codigo - Clasificacion - Cantidad - U. Medida - Descripcion - Numero - Descripcion - entidad - dependencia - tipo de procedimiento - fecha de publicacion - precio referencia - nombre -telefono - correo electronico 13. if shows errors loading the page or dont display data, reload or refresh page or mark as error and try later 14. click on the next button of the results page. 15. if clicking on the next button shows any kind of error, wait 5 secs,go back and click on the next again 16. repeat until the end 17. sum 12 days to the starting date 18. sum 12 days to the ending date 19. repeat the loop with the new dates. 20. repeat loop until the end of the year. I need to scrap from 2009 to 2016

Bonjour, Working for 10 years as a consultant I would be happy to perform this mission of scraping website. I like to innovate, build, participate in the design of complex architectures subject to strong constraints (volume, availability, languages, performance, ...). I attach great importance to technological monitoring and I strive to always be a free electron orbiting the web sphere. What motivates me now? Simply continue to take on new challenges right now. Do not hesitate to contact me here or on skype with pseudo defkrie if you have any questions.

Hi there! I am an expert American programmer specializing in webscraping with experience developing custom applications and collecting data from hundreds of websites for clients here on Freelancer. I did a bit of research on this website and could handle this for you in just a day or two. I would write an app that automates a browser, inputting the searches and looping through the items collecting the data points you specified. I would make sure the app uses 12 day periods per your suggestion as well to make sure we don't miss any data since there is 50 returned record limit. In addition to collecting the data I would provide you with the app as well which you could run in the future on any Windows PC should you wish to get updated data. I can't send you a PM unless you message me first. Please send me a message so we can speak further about the project details! Thanks, Mike
