A couple years ago I wrote a CGI script which read a file of of disk, turned all the HTML table cells into form areas of the magically right size, and allowed a novice user to edit the page in this fashion. (When they submitted the form, it inserted the contents of the form into the appropriate places in the same file.) Unfortunately, the whole system was line-based instead of tag-based, which made it somewhat fragile.

Now I'd like to rewrite it to be tag-based. HTML::Parser looks like it will be my friend here, and maybe even HTML::TableExtract

However, I seem to missing a simple concept with HTML::Parser-- I can't figure out how to use it edit a file in place. The logic would be: "If I've found a table cell, process it, and stick the contents and stick it back the HTML stream". Could someone provide an a barebones example of this logic to jump start me? Thanks!
