[xml] XML Error: Extra content at the end of the document

This is the XML:

<?xml version="1.0" encoding="ISO-8859-1"?>
<document>
<name>Sample Document</name>
<type>document</type>
<url>http://nsc-component.webs.com/Office/Editor/new-doc.html?docname=New+Document&amp;titletype=Title&amp;fontsize=9&amp;fontface=Arial&amp;spacing=1.0&amp;text=&amp;wordcount3=0</url>
</document>

<document>
<name>Sample</name>
<type>document</type>
<url>http://nsc-component.webs.com/Office/Editor/new-doc.html?docname=New+Document&amp;titletype=Title&amp;fontsize=9&amp;fontface=Arial&amp;spacing=1.0&amp;text=&amp;</url>
</document>

When I open it it says: This page contains the following errors: error on line 8 at column 1: Extra content at the end of the document

But when there is only this:

<document>
<name>Sample</name>
<type>document</type>
<url>http://nsc-component.webs.com/Office/Editor/new-doc.html?docname=New+Document&amp;titletype=Title&amp;fontsize=9&amp;fontface=Arial&amp;spacing=1.0&amp;text=&amp;</url>
</document>

Why is it saying this when there is two?

I've found that this error is also generated if the document is empty. In this case it's also because there is no root element - but the error message "Extra content and the end of the document" is misleading in this situation.
