copied!<p>If you want to split up path elements, look at <a href="http://search.cpan.org/dist/File-Spec" rel="nofollow noreferrer">File::Spec</a> or <a href="http://search.cpan.org/dist/Path-Class" rel="nofollow noreferrer">Path::Class</a>, which handle all of the operating system specific stuff:</p> <pre><code> use File::Spec; my( $root, @path_parts ) = File::Spec->splitdir( $path ); </code></pre> <p>The nice thing about keeping the root is that you can go backward easily and still keep that leading slash (or whatever your opearting system might use):</p> <pre><code> my $path = File::Spec->catfile( $root, @path_parts ); </code></pre> <p>This isn't such a big deal with URLs since they all use a unix-like path specification. Still, it's easy to construct the local path in the same way, and remember where the root is (which may be important on Windows, VMS, etc):</p> <pre><code> my ($docroot_root, @doc_root ) = File::Spec->splitdir( $ENV{DOCUMENT_ROOT} ); my $local_path = File::Spec->catfile( $docroot_root, @doc_root, @path_parts ); </code></pre> <p>Otherwise, you're stuck with what split does. It assumes that you care about the position of fields, so it preserves their position (i.e. the thing before the first separator is always position 0 in the list, even if it is empty). For your problem, I tend to write it as a list assignment where I use a variable to soak up the initial empty field, just like I'd do with </p> <pre><code> my( $root, @path_parts ) = split m|/|, $path; </code></pre>
