Practical Perl Tools: Mind Those Stables, I Mean Files

In the last column, we had a lovely visit with the XML Path Language, or XPath, followed by a brief look at how to bring its power to bear using Perl. Path-like things have been a bit of a leitmotif here over the past few columns, so I thought we might want to continue in this direction. This time we’re going to look at a library/tool that takes this abstraction and puts it to practical use in an interesting way we haven’t seen yet. As regular readers of this column will tell you, I loves me a good abstraction now and then. Sure do.
