Although I prefer to go directly from XML to text or HTML  without going through JPEG or other bitmaps, 

 I think it might be useful to add to Lunis's suggestion:

a) I just took such a screen capture, pasted into  Microsoft OneNote, and then did "Copy Text from Picture",  and it worked

b)  conversely,  the SnagIt screen capture application which I had installed recognized that the Dragon Command Browser is a scrolling window, rolled it automatically, but did not manage to capture anything except the last   windowful.

Anyway, there are ways to go from screen captures to useful stuff like text  or HTML.    OK in if you're doing it as a one-off, not so good if you want to do this regularly.
