Categories and metadata not working with wp xml import

Hello,
I’m attempting to import data with the syntax created by WP’s new export feature. I should make it clear that the data I’m attempting to import wasn’t actually exported by wordpress, but through the use of scripts, it appears to be exactly the same.

The problem is that the categories, the metadata, and the dates refuse to map correctly. Has anyone attempted to do this before? Has anyone experienced the same trouble?

Here is some of the code (one item) I’ve generated:

<item>
<title>Post Title</title>
<link>removedforforum/?p=16/</link>
<pubDate>Mon, 10 May 2004 08:50:00 -0400</pubDate>
<dc:creator>admin</dc:creator>
<dc:subject>Category Name</dc:subject> 				<guid isPermaLink="false">removed/?p=16/</guid>
<description></description>
<content:encoded><![CDATA[<p>Blah Blah Blah</p><ul><li>list one</li><li>list two</li></ul>]]></content:encoded>
