Mojolicious contains an excellent tool kit that includes Mojo::UserAgent and Mojo::Dom. Here's a one liner:

perl -Mojo -E 'say g("perlmonks.org")->dom->at("title")->text'
[download]

Output:

      PerlMonks - The Monastery Gates
[download]

Minimally, Mojolicious requires no additional external dependencies --just a relatively recent Perl. The distribution size is around 2MB once it's unpacked and installed, and it takes about a minute to install:

cpanm Mojolicious
[download]

...or via your preferred module installation technique.
