Google Webmasters won’t accept my sitemap

Hi all,

I’m trying to submit my sitemap.xml file to Google Webmasters tools but it keeps telling me this: “Unsupported file format”.

This is how my sitemap looks like:

<?xml version="1.0" encoding="UTF-8"?><?xml-stylesheet type="text/xsl" href="https://rauru.com/wp-content/plugins/google-sitemap-generator/sitemap.xsl"?><!-- generator="wordpress/2.3.3" --><!-- sitemap-generator-url="https://www.arnebrachhold.de" sitemap-generator-version="3.0.3" --><!-- generated-on="March 10, 2008 3:00 pm" --><urlset xmlns:xsi="https://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="https://www.sitemaps.org/schemas/sitemap/0.9 https://www.sitemaps.org/schemas/sitemap/0.9/sitemap.xsd" xmlns="https://www.sitemaps.org/schemas/sitemap/0.9">	<url>

Can anyone point out what the problem is?

Thanks in advance!
