[one-users] ONE-2.0 CDATA in XML output

[Shi Jin]

I got it. Somehow if the output is
<CPU>
   <![CDATA[2]]>
</CPU>
in multiple lines, it does not work.

If it is just one line:
<CPU><![CDATA[2]]></CPU>
It works.

But my opennebula-2.0.01 (git) outputs them in multiple lines.
I see an older version puts them in a single line. Maybe this is why hector
gets his to work.
So the questions are:
1. can we put them back to a single line?
2. Shall we still be able to parse XML CDATA on multiple lines?

Thanks.
