curl, grep, sed... these are fundamental nix commands, but it also involves navigating the details of these commands. In contrast, REBOL offers a simple approach:
url: read http://slashdot.org/index.rss
parse/all url [
any [
<title> copy title to </title>
(print title)
|
<description> copy desc to </description>
(print desc)
|
skip
]
to end
]
REBOL is free and platform-independent (although not OSS). It's a very handy, very tiny, cross-platform scripting shell -- and it provides a capable built-in GUI (not yet on OSX).
