MagpieRSS isn’t perfect, there are a number of issues with using it.

• Some versions of Magpie do not parse <category> tags correctly, it concatenates all the category strings into a single long category instead of making an array of categories.
• By default, as with PHP in general, Magpie does not output UTF-8, instead it will output ???? ???? characters. To resolve this, add define(“MAGPIE_OUTPUT_ENCODING”, “UTF-8”); to Magpie.
• Namespace confusion. Magpie treats namespaces the same as encapsulating elements, so <dc:subject> would map to an array subject in an array dc. This can result in collision if a real encapsulating element name collides, ie <dc><subject/></dc>. This is intentional, as MagpieRSS intends to make dealing with namespaces less complicated.
• Local RSS cannot be accessed. If there is an RSS feed on the local drive, MagpieRSS doesn’t support accessing it directly.
• RSS feeds requiring Cookies are not supported
• Local proxies are not supported

Note: Some of these issues are by design. Namespace simplification in particular makes it easier to work with RSS feeds.

Also a development build is available that addresses some issues as MagpieRSS progresses towards version 0.8.
