Hows Mozenda Screen Scraper coded?

I want to know how is the Mozenda Screen Scraper coded?

http://www.mozenda.com/screen-scraper

I shows a browser where user can select the fields he wants to scrap and it creates a crawl script out of it.

The crawl script generation part is clear to me, I want to know does it record the user ac开发者_JS百科tions which the user is doing in the browser.

I want to do something similar using C#.

I guess they run something like iMacros on the backend. I even noticed the iMacros browser icon in some of their screenshots ;-)

If you want to code something like this yourself in C#, the IE webbrowser control is the best starting point!

@yc08m, I can tell you for sure that they are not using iMacros. It is all coded with their own proprietary code.

I realize this is an extremely outdated post, but they seem to rely heavily on XPath, so first things first you would need to load the page into an object that you can query. I'd recommend using something like Html Agility pack to accomplish this.
