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 tag).
Given your specific example, I notice that most of the examples consist
of lines ending in , so for this specific case, you might use:
awk 'BEGIN{ l=1 } $0 ~ /$/ && $1 ~ /^[^<]/ { $0 = l++ " "
$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 ($0 ~ /$/ && $1 ~ /^[^<]/)
$0 = l++ " " $0;
else
l=1;
print;
}'

[vox-tech] adding line numbers to an HTML file
Hi everyone, wondering if there is a simple way to add line numbers to every non-html tag in a webpage: here is a dirty hack that does not work very well: lynx -source http://casoilresource.lawr.ucdavis.edu/drupal/node/319/print | cat -n > test.html or - if there is a way to add line numbers to non-tag data, similar to how the paste (http://rafb.net/paste/) service works. any ideas would be very helpful! -- Dylan Beaudette Soils and Biogeochemistry Graduate Group University of California at Davis 530.754.7341 ___ vox-tech mailing list vox-tech@lists.lugod.org http://lists.lugod.org/mailman/listinfo/vox-tech
