This one is similar to the previous post, only now we have images stacked vertically (using two different classes) and with captions underneath the images:

Quick Perl template for Line and String Manipulation

We've got to tamper with some flat files (ultimately turning them into valid xml) - here's some quick notes (in the form of a *very* simple perl script) on the steps involved in:

- taking a filename as an argument (argv[0])
- opening the file
- keeping tabs on the line you're working on within the file (we use $. for this)
- getting access to the contents of each line within perl (we use $_ for this)

you would run this using something like:

./ the-name-of-the-textfile.txt
