some clarification is indeed warranted:

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?
