Duplicate the button you made when extracting links. Change the function call getLinks to getText; the rest of the script can remain the same.

Edit the script of the test stack and add this function:

function getText pPageSource
  put replaceText(pPageSource,"(?:<(?P<tag>script|style)[\s\S]*?</(?P=tag)>)|(?:<!--[\s\S]*?-->)|(?:<[\s\S]*?>)","") into pPageSource
  replace lf with "" in pPageSource
  replace tab with " " in pPageSource
  return pPageSource
end getText

Try clicking on the button you just made. You should see your second field filled with just the text parts of the web page.

Copy the function and go back to the WebScraper stack script. Paste the function there.

Go to the Text card of the stack and from the MobGUI window, drag the Multiline Text control onto the card. Set its name...
