I need a tool which can read some specific data from a website. Based on the data retrived i will make some calculations. Is there a tool that can read a HTML page and retrive some values displayed in it? The data are shown in table format in that website. This website is probe which displays some memory usage of a server. We take some statistics from this page and make calculations like taking average etc. This task is now being done manually for evry 30 minutes. We need to automate it.
