App That Will Scrape Numbers Off Of A Webpage?
May 24, 2011I'm trying to make an app that will scrape numbers off of a webpage. What I want to do is have it read the Game Name and then Views (for statistics keeping). The WebPage is set up like
<tr class="odd">
here are 7 <td> tags that display different things
</tr>
[Code]....
I'd like the app to check the second TD tag to see if it's innertext says, lets say, 'GAME', and then if it does, it adds the innertext of the 7th TD tag (which is a number), to the total sum, and it scrapes all of that info off the page.
I can understand the logic of how to process the info, but I have no clue as to reading the correct tags.
Scrape Some Information Off Of A Webpage That Is Heavily Javascript Enabled
Mar 27, 2011I am *VERY* new to web-scraping and am trying to scrape some information off of a webpage that is heavily javascript enabled. An example of the page I am trying to scrape from is: [URL] I am trying to scrape the property links such as "322 E 98th St" The text appears on the webpage and I can find the link myself, but it doesn't appear in the page source code.
I am trying to scrape it using the webbrowser control using the WebBrowser1.DocumentText property, but it doesn't even show the links simply when I view the source in ie. I am sure this has something to do with the javascript it uses to load up the page or maybe iFrames,
VS 2010 Scrape Multiple Words That Meet A Criteria Form A Webpage.
Apr 22, 2011Ok so basically heres what i need to do: Extract text from the webpage that meets a certain criteria. There will be a ton of these on 1 page and i would like to add them to a rich textbox on sperate lines.

C# - HTMLAgilityPack And Timeouts On Load
May 3, 2011I'm using HTMLAgilityPack in a parser that I have up on a server, but I'm having issues with one of the websites that I'm parsing: Every day around 6am they tend to shut down their servers for maintenance, which throws off the Load() method for HTMLWeb, and makes my app crash. Do any of you guys have a more secure way of loading a website into HTMLAgilityPack, or maybe some way to do error checking in C# to prevent my app from crashing? (my c# is a little rusty). Here is my code right now:
HtmlWeb webGet = new HtmlWeb();
HtmlDocument document = webGet.Load(dealsiteLink); //The Load() method here stalls the program because it takes 1 or 2 minutes before it realizes the website is down
