Ability to return HTML of the selected element

[ch3ckmat3]

When some element is scrapped using xpath, the rendered text of that element is returned, and the inner HTML is stripped. Sometimes we need the inner HTML of that element and want to process the HTML ourselves for the sake of the structure and other details of the scrapped data.

Can we add a switch to enable or disable HTML stripping where we add xpath elements for a job and save the results accordingly?
