[REBOL] REBOL Script to convert REBOL format to RSS XML
From: premshree:pillai:gm:ail at: 31-Dec-2004 2:46
Hello,
So I wrote a small script that generates valid RSS 2.0 feeds from the
REBOL data for Carl's blog. I don't know where else to post the code
(because it won't be of use generally), so I'm posting it here:
=== BEGIN REBOL CODE ===
REBOL [
Title: "RSS Generator for Carl's Blog"
Date: 31-Dec-2004
Version: 0.0.1
File: %carl-rss.r
Home: http://www.livejournal.com/~premshree
Author: "Premshree Pillai"
Version: 0.0.1
Purpose: {
Generates valid RSS 2.0 feeds for Carl's blogs
}
]
;; channel data
channel: [
title "Carl's REBOL Blog - Vive la REBOLution"
link http://www.rebol.net/
description "describes this blog channel"
language "English"
copyright "2005 Carl Sassenrath"
generator "REBOL Messaging Language"
]
;; blog items go here
items: [
[
title "Blog item title...."
link http://www.rebol.net/cgi-bin/blog.r?view=0080
author "Carl Sassenrath"
pubdate 30-Dec-2004
content {the blog goes here}
]
[

write %carl-rss2.xml output
=== END REBOL CODE ===
The REBOL data in Carl's blog (see
http://www.rebol.net/cgi-bin/blog.r?view=0080) doesn't provide the
time of posting, so it just takes it as 00:00:00 GMT, but that's okay,
I guess.
If there are improvements possible, please point so/do so. :)
Thanks.
