I use wget -O - to output the content of the page to standard output, and
then an appropriate mix of grep, sed, awk, head, sort and tail to find the
content I need, for example I use the following crontab entry to identify
the URL for the downloadable version of the telegraph, download the PDF and
print it.

0 18 * * 1-5 wget  -O -  http://www.telegraph.co.uk`wget -O -
http://www.telegraph.co.uk/pm | grep -o -E
| sort -r | head -n 1`| lpr -P tp1 -o outputorder=reverse #Telegraph
