screen-scraping

I am trying to screen scrape using C#.It works for few times,after which i receive Session expired error.Any help will be appreciated. Brett Allen Here is the set of classes I am using for screen scraping. (I wrote these classes, feel free to use however you want.) There may be some bugs in it, but every usage I have for it it works quite flawlessly. It also handles SSL websites fine, works with redirects, and captures the original pages that caused a redirect as well in the WebPage class. using System; using System.Collections.Generic; using System.IO; using System.Net; using System.Text;

I am trying to get stock prices by scraping google finance pages, I am doing this in python, using urllib package and then using regex to get price data. When I leave my python script running, it works initially for some time (few minutes) and then starts throwing exception [HTTP Error 503: Service Unavailable] I guess this is happening because on web server side it detects frequent page updates as a robot and throws this exception after a while.. is there a way around this, i.e. deleting some cookie or creating some cookie etc.. or even better if google gives some api, I want to do this in

I have a project at work the requires me to be able to enter information into a web page, read the next page I get redirected to and then take further action. A simplified real-world example would be something like going to google.com, entering "Coding tricks" as search criteria, and reading the resulting page. Small coding examples like the ones linked to at http://www.csharp-station.com/HowTo/HttpWebFetch.aspx tell how to read a web page, but not how to interact with it by submitting information into a form and continuing on to the next page. For the record, I'm not building a malicious and

I am relatively new to the whole idea for HTML parsing/scraping. I was hoping that I could come here to get the help that I need! Basically what I am looking to do (i think), is specify the url of the page I wish to grab the data from. In this case - http://www.epgpweb.com/guild/us/Caelestrasz/Crimson/ From there, I want to grab the table class=listing in the div id=snapshot_table. I then wish to embed that table onto my own page and have it update when the original content is updated. I have read a few of the other posts on Google and Stackoverflow, I also had a look at a tutorial on Nettuts+

I have a PHP-script that loads page-content from another website by using CURL and simple_html_dom PHP library. This works great. If I echo out the HTML returned I can see the div-content there. However, if I try to select only that div with the simple_html_dom, the div always returned empty. At first I didn't know why. Now I know that it's because its content apparently is populated with javascript/ajax. How would I get the content of the site and then be able to select the div-content AFTER the javascript has populated it with the correct content? Is it even possible? Thanks! Yes its piece

i need something like iMacros for Python. It would be great to have something like that: browse_to('www.google.com') type_in_input('search', 'query') click_button('search') list = get_all('<p>') Do you know something like that?
