Web Request A Specfic Element In A Webpage Using Id?

Jan 19, 2010

I would like to use the WebRquest Class in Visual Basic to get the Inner Text or Inner HTML of a specific element in the requested web page.For instance, if the webpage contains an element with the id ="label1" and has inner text ="hello" then I should use the WebRquest to extract the inner text of the specified element and not the source of the whole page. Note that I do know the alternative solution , which is using the Web Browser Control . But unfortunately this is unsuffiecent for my application.

Feb 14, 2012

I have a number of rewrite rules for a lot of things that I did in IIS7, like removing trailing slashes, canonnical URLs, lowercase lettering, and such. IIS altered my web.config, and everything works fine on the website, like it should. But in the Visual Studio web.config, the opening < rewrite > statement is underlined in blue, and at the bottom of VS, it says that the element 'system.webServer' has invalid child element 'rewrite'. But this is how IIS made it. I didn't do this manually. Should I be concerned with this VS error, or should I just leave as be, since it's working how it should work? Here's an example of my web.config:

Therefore, if I have a querystring key and cookie key which are the same, which value is returned?
