A ScrapeMap InstructionSet contains all DataAddresses and Actions relevant to one type of source webpage. The first InstructionSet created in the ScrapeMap is the Root InstructionSet. If another page is browsed to, for example when clicking on a link to get additional data, a new InstructionSet is created. In the screenshot below the Root InstructionSet is selected. Name has been given a value of “Root InstructionSet” and the URL references Best Buy. These values can be changed in this dialog.
The URL of a root InstructionSet determines the first page that will be scraped. To change the first page or the sorting and filtering of this first page close the ScrapeMap. Then browse to your prefered page and apply the filtering and sorting you wish. Then copy the new URL displayed at the top of the Source Browser Pane. Reopen the original ScrapeMap and open the Properties Detail for the ScrapeMap. Click on the Root Instruction Set in the left pane, and paste the previously copied new URL, overwriting the old URL in the right pane. Click OK and return to Save the revised ScrapeMap.
The screen shot below shows an example of selecting a second InstructionSet. The Name for this second InstructionSet is “ClickLink InstructionSet”.
