OK, here's another interesting problem for you.
The page source for the comic "Power Nap" splits its image URLs with a line break, as in the following:
<img src="http://www.powernapcomic.com/
2015/pnap20150406.jpg" border=0><br> </td></tr></table> <!— del comic—>
Now, if I just try to capture the entire URL, the line break is read in (incorrectly, of course) as part of the URL, and Woofy gets a 404 error instead of an image. But I also can't just capture the portion following the line break as if it were a relative URL, since the page's URL is http://www.powernapcomic.com/d/20150406.html. (Note the extra "d" directory which isn't part of the image's URL.)
So, what I need to do is either (a) capture the entire URL but have Woofy either delete the line break character before attempting to download or simply ignore the line break character completely, or (b) capture the "relative" URL and then construct the download URL by prepending "http://www.powernapcomic.com/" to it.
Are either of those possible in a Woofy definition file?
