get_body
get_body(); - get the page content (the current body of the page body, taking into account all JS worked out at the moment).
Note: This function gets the page body as the body of the main frame, without taking into account the content of other frames. To get the body of other frames, you can use the $frame.
After testing, the function returns the result of its work to the script :
Page Body – the body of the current page at the moment
