Hello, I am trying to gather data from the following page: http://toast.gasunie.de/Pages/search.aspx?lang=en&soid=GUD I am trying to get hourly data. I did the following: url = "http://toast.gasunie.de/Pages/search.aspx?lang=en&soid=GUD" getFormParams(url) fair enough, this did not return any sensible name=value parameters I could use. I then looked into the HTML code to find name=value parameters that would help me. I found the following name=value pairs, and set: today = format(Sys.time(), "%d.%m.%Y") ctl00_MainContent_webDatePickerFrom_DrpPnl1_DP_CAL_ID_1=today, ctl00_MainContent_webDatePickerTo_DrpPnl2_DP_CAL_ID_2=today GasQuality="H", PointType="EN", PointList="H070", Publishers="HourValues", ListHourValues="HTLF", Submit="Weiter" So I went on and tried getForm() and postForm() with the above parameters, but it did not show any success. So I THINK the problem is that the webapplication is returning the table on a different URL as the one above, please have a quick try with the webapplication. How can I come by this problem? Best, and thanks Sven -- View this message in context: http://r.789695.n4.nabble.com/Webscraping-Data-RCurl-tp4631500.html Sent from the R help mailing list archive at Nabble.com.
