+NAME
+
+ MagpieRSS - a simple RSS integration tool
+
+SYNOPSIS
+
+ require_once(rss_fetch.inc);
+ $url = $_GET['url'];
+ $rss = fetch_rss( $url );
+
+ echo "Channel Title: " . $rss->channel['title'] . "";
+ echo "
";
+ foreach ($rss->items as $item) {
+ $href = $item['link'];
+ $title = $item['title'];
+ echo "- $title
";
+ }
+ echo "
";
+
+DESCRIPTION
+
+ MapieRSS is an XML-based RSS parser in PHP. It attempts to be "PHP-like",
+ and simple to use.
+
+ Some features include:
+
+ * supports RSS 0.9 - 1.0, with limited RSS 2.0 support
+ * supports namespaces, and modules, including mod_content and mod_event
+ * open minded [1]
+ * simple, functional interface, to object oriented backend parser
+ * automatic caching of parsed RSS objects makes its easy to integrate
+ * supports conditional GET with Last-Modified, and ETag
+ * uses constants for easy override of default behaviour
+ * heavily commented
+
+
+1. By open minded I mean Magpie will accept any tag it finds in good faith that
+ it was supposed to be here. For strict validation, look elsewhere.

- * NOTES ON RSS PARSING PHILOSOPHY (moderately important):
- * MagpieRSS parse all versions of RSS with a few limitation (mod_content, and
- * mod_taxonomy support is shaky) into a simple object, with 2 fields,
- * the hash 'channel', and the array 'items'.
- *
- * MagpieRSS is a forgiving and inclusive parser. It currently makes no
- * attempt to enforce the validity on an RSS feed. It will include any
- * properly formatted tags it finds, allowing to you to mix RSS 0.93, with RSS
- * 1.0, with tags or your own imagining. This sort of witches brew is a bad
- * bad idea! But Magpie is less pendantic then I am.
