You're repeating the question. Manually: I think you can select the text by clicking and dragging your mouse pointer over the location of the text. Programmatically: you'll have to parse the content stream; that's not easy, but not impossible either. Just make sure you look for the render mode operator and find out where it's set to invisible.
