Question

Using ASP.net, what methods can I use to do the following:

1. Open up a connection to a given URL to read HTML content
2. Parse the given URL for hyperlinks, and place them in an array
3. Loop through each hyperlink (only 1 level down), opening each one, saving the HTML contents in a table, and move to the next hyperlink until done.

If ASP.net is not up to the task, other languages or free scripts/toolkits would be acceptable.

Thanks.

Answer 1

• Use a System.Net.WebClient for step 1.
• Use System.Text.RegularExpressions as shown here for step 2.
• Create and use a System.Data.DataTable for step 2.
• See here for step 3

I left out the obvious things, such as “loop through the DataTable”, etc. A more in-depth answer is probably not something that will be coming from this site. The question is a bit too big to answer completely here.
