How can I download only part of a page?

Question

I have 100 pages on my site, but I want download only part a page instead of all page content.

I want just one box of each page to download, the file size is 10 KB. For this I Use WebClient and htmlagilitypack .

 WebClient Client = new WebClient();
 var result = Encoding.GetEncoding("UTF-8").GetString(Client.DownloadData(URL));

Answer 1

Unfortunately, that's not possible, because HTTP is not designed to deliver a specific part of a web page. It does support range requests, but for that you would need to know where exactly (in terms of bytes) the desired content is located.

You can

• download the whole page and then
• use a HTML parsing library to extract the part you need.
