here is a dirty hack that does not work very well:
lynx -source http://casoilresource.lawr.ucdavis.edu/drupal/node/319/print

or - if there is a way to add line numbers to non-tag data, similar to

the page in question
(http://casoilresource.lawr.ucdavis.edu/drupal/node/319/print) produces
printer-friendly output (simple html). I would like to add line numbers to
this document so that the students in my class can easily refer to specific
lines of code. In my hack posted above, i add a line number to *every* line -
even html tags like head, body , etc. I would like to add line numbers to
the text in-between html elements. i.e
body
1 something
2 about
3 some other thing
4 here
...
/body
perhaps some regex-fu is required?
A quick awk script I whipped up earlier when you first posted was:
awk 'BEGIN{ l=1 } $1 ~ /^[^]/ { $0 = l++ $0 } { print }'
Which takes its input and prepends an incrementing line number before
any lines that don't start with a as their first non-space
character. That's almost as stupid as cat -n, though, as it will add
attributes before lines that are part of a tag spread across multiple
lines, and will fail to add line numbers before lines that consist of
mostly textual content (such as a line that is wrapped in a b tag).
Given your specific example, I notice that most of the examples consist
of lines ending in br, so for this specific case, you might use:
awk 'BEGIN{ l=1 } $0 ~ /br$/ $1 ~ /^[^]/ { $0 = l++ nbsp;
$0 } { print }'
Which helps limit it to the lines in the examples.
If you want them to reset for each example, the following might work:
awk 'BEGIN{ l=1 }
{
if ($0 ~ /br$/ $1 ~ /^[^]/)
$0 = l++ nbsp; $0;
else
l=1;
print;
}'
