XML Parsing Error: not well-formed

Question

I get the above error when viewing a xml document. The problem seems to be the second ( = ) in the following link.

http://mysite.com/viewpage.php?u=1020&op=new

In the link & is replaced by & amp; without the space. Any help as to why this is throwing an error would be greatly appreciated.

This is how the link is added to the xml file structure

<item link="http://mysite.com/viewpage.php?u=1020&amp; amp;op=new">
   <![CDATA[Some text and other stuff here]]>
</item>
