in reply to Hints & Tips on passing HTML?

If you are extracting information from pages with a similar format: HTML::TokeParser. Fetching the pages from a different server? Use LWP.

TokeParser easily strips out the text above:

#just to give you an idea about extracting text #not complete or tested while(my $token = $stream->get_token()){ if(($token->[0] eq 'S') && ($token->[1] eq 'td')){ my @tokens; my (@headers, @links); push(@tokens, $stream->get_token()) x 2; if(($tokens[0][0] eq 'S') && ($tokens[0][1] eq 'b')){ push(@headers, $tokens[1][1]); } if(($tokens[0][0] eq 'S') && ($tokens[0][1] eq 'a')){ push(@links, $tokens[0][2]{'href'}); } $stream->unget_token(@tokens); } }

When redisplaying that information, push it into a nice template using HTML::Template. Make it dynamic using CGI and the CGI module.

[GrandFather]: That's ok when the signal is a voltage, but there are three axis accelerometers, gyroscopes and magnetometers in these things! A little invention is needed at times!
[Corion]: GrandFather: Yeah, in that aspect, hardware is far more a black box than software
[GrandFather]: Oh, and the manufacturer tells lies too! I'm sure they don't mean to, but I know for sure some of the stuff they say is just wrong. It's possible they don't understand what we are asking, but that's not a good look either
[Corion]: GrandFather: Ah, unit testing hardware is fun, especially when the hardware is uncalibrated ...
[GrandFather]: Us: "What scaling do we need to apply to the numbers from the SDK for the wibble?". Them: "Oh, the numbers from the SDK for the wibble are already correct, they don't need scaling"
[GrandFather]: In our code: wibble range 1 scale by 1, range 2 scale by 2, range 3 scale by 4, range 4 scale by 8
