XML Validation error : EntityRef: expecting - nodejs

[lafama]

To avoid the above error in nodejs i am proposing if it is possible to use this
<url> <loc><![CDATA[http://www.example.com/?id=10&param2=112]]></loc> </url>
or (Note & has been replaced with &amp)
<url> <loc>http://www.example.com/?id=10&amp;param2=112</loc> </url>
