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

[Shi Jin]

Really? I am confused.
Can you run the following code and see if your output is the same as mine?
[cloudadmin at rhel6-one2 cgroups]$ cat test
#!/usr/bin/ruby
require 'rexml/document'
vmcdata=<<XML
<CPU>
   <![CDATA[2]]>
</CPU>
XML

doc=REXML::Document.new(vmcdata).root
puts doc
puts doc.text

vmold=<<XML
<CPU>
2
</CPU>
XML

docold=REXML::Document.new(vmold).root
puts docold
puts docold.text
[cloudadmin at rhel6-one2 cgroups]$ ./test
<CPU>
   <![CDATA[2]]>
</CPU>


<CPU>
2
</CPU>

2
[cloudadmin at rhel6-one2 cgroups]$ ruby --version
ruby 1.8.7 (2010-06-23 patchlevel 299) [x86_64-linux]


Thanks.
