ASP.net ques: Webpage data retrieval and parsing

[news.microsoft.com]

Hi again, I am pretty new to ASP.net (I use to be a Visual Basic 6 addict)

I want to do the following but I have been unable to find good info/ or
sample code on it; please help;

- retrieve a webpage using ASP.net from another site (the url have
parameters like (domain.com/?date=january) in it if that makes a difference)

- using ASP.net code I want to Parse a table (perhaps using DomDocument
object?) I want to retrieve data from the table cell first by row and
then by column.
(retrieve the data to be store in data object)

- Then I want to use the data object to display the information retrieve in
webpage?


I am looking for sample codes, references or anything of that nature to help
me.
Thank you in advance. and please be as detail as you like.

Joe.

Webzinc is a good component for parsing Web pages:

I am looking for free tutorials, sample codes, references concerning my
questions.

I do hope ASP.net does have something free. Or else I might have to stick
with PHP. LOL

Use System.Net.WebClient or System.Net.WebRequest.

Use the HTML Agility Pack

Hello,
Just follow the following..

1.
// Create the WebRequest for the URL eg www.domain.com/?date=january
WebRequest req = WebRequest.Create("www.domain.com/?date=january");

2.
// Get the stream from the returned web response
StreamReader stream = new
StreamReader(req.GetResponse().GetResponseStream());

3.
// Get the Source of teh html page.
string HtmlSource = stream.ReadToEnd();

Now you have all the source of the HTML page. Just use the regular
expression and search in the page.

Hope it can be of any use for you.
