This will contain all of the contents of the features div and nothing else. Often you want to capture page content after the user has interacted with it in some way, for instance after filling out a form. GrabzIt enables you to do this by providing the ConvertPage method. This method must be called on a web page accessible on the internet.

The example creates a copy of the source of a webpage updates it with any form values and passes it to GrabzIt to be converted. As we only want to capture the div divSectionas shown above we are passing that as a target.

However you could not specify the JSON parameters and capture the whole webpage as it has been updated by the user.

Depending on the nature of the website you are capturing you may also use this approach to capture content that is behind a login.

Simply use the above approach, with or without the target parameters as desired. Then as long as the page resources are not restricted in anyway you should be able to capture the webpage content as seen by the user. Terms and Conditions. Privacy Policy. GrabzIt Data Processing Agreement.
