in reply to How to process html script with perl

At first, I thought that you wanted to parse an HTML file as an input, to get information out of it.   For that purpose, I would have suggested that you search for "html parse" at http://search.cpan.org.

But instead I think that you may want to generate a customized HTML content using the file shown above as a template.   There are numerous templating engines available in Perl.   My personal favorite happens to be Template::Toolkit.   Although it is most often used in interactive web-sites, it can be used very well in situations like this, especially when you would like to vary what is produced, e.g.: "Thank you for your payment! :-)" vs. "Pay Up Now, You Scum, Or Your Parakeet Gets It! :-[" depending on the balance.

Start with this tutorial, which deals specifically with how to generate a file (or a string) from a templated source:   Template::Tutorial::Datafile.

[jdporter]: one prog I have has a UI which allows to input a bit mask
[jdporter]: currently it expects the bitmask to be in the form of a hex number, e.g. 0x0101
[jdporter]: but I'd like to let the user specify it as individual bits, i.e. 0b0000000100000001
[jdporter]: there is no bit/binary equivalent of hex, right?
[jdporter]: I guess that the most direct way of doing it is with some magical incantation involving unpack or whatever
[jdporter]: let me google that for me ;-)
[jdporter]: hex points explicitly to oct, which does the job. :-D
