totally agree that scraping html is quite bad and unstable. my rough guide for scraping, from most to least desireable
- don't scrape...if you can find out if there's a RESTful way to get the results instead, via some API or alternate (e.g. XML format) url
- if the html is well formed (i.e. xhtml) then it will be almost guaranteed to be well structured, will proper closing tags etc...so use one of the XML based parsers. you can easily get to specific elements via a well defined hierarchy once parsed
finally, if you end up producing html in the CGI, don't mix actual output with styling. write a stylesheet instead. producing a well formed xhtml document in the CGI without inline styles, provides later opportunity to use the output of the CGI via another CGI or whatever. it's also much easier to change the output of the CGI via a stylesheet, rather than digging in perl code.
the hardest line to type correctly is: stty erase ^H
