WebNavigator helps creating search agents to retrieve dynamic data from the Web.
An awful lot of websites let users search their data using web interface. Usually these contents are not accessible via search engines such as Google.
WebNavigator allows to:
define sites to be searched
choose the search criteria
define the result area inside the page
choose conditions to classify the results (no results? no new results? something new)
receive notification for update
