There are so many links of the form
http://example.com/file001.xhtml http://example.com/file002.xhtml and so on.
How would you render them in a browser (for example, in Chrome) and save to PDF?
Hands through the "Print" is not an option, since there are quite a few links. It seems to be a very primitive task, but I can not figure out how best to deal with it?
