How to get rid of the problem about google sitemap?

[chokan]

Recently, I just create a google sitemap,

Below is a snippet of my google sitemap

<?xml version="1.0" encoding="UTF-8"?>
- <urlset xmlns="http://www.google.com/schemas/sitemap/0.84" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.google.com/schemas/sitemap/0.84 [google.com...]
- <url>
<loc>http://www.domain.com</loc>
<lastmod>2005-09-07T21:40:46+08:00</lastmod>
<priority>1.0</priority>
<changefreq>weekly</changefreq>
</url>
-----------------------------------------
In my google account, I can see the status of my sitemap is invaild date, but I can't see anything wrong about my sitemap's data section.

Please help me. TIA.
