Let us test by adding some XML content in the article body to see if the XML content displays perfectly fine.

<?xml version="1.0" encoding="utf-8"?>
<ROOT>
<BUTTON caption="Select Language" img="6" hint="Select Language" command="">
<MENU img="" type="None" >
<ITEM caption="English" img="1" command="en"/>
<ITEM caption="France" img="2" command="fr"/>
<ITEM caption="Russian" img="3" command="ru"/>
</MENU>
</BUTTON>

<COMMANDS>
<SPECIAL type="Switch to" name="en" />
<SPECIAL type="Switch to" name="fr" />
<SPECIAL type="Switch to" name="ru" />
</COMMANDS>
</ROOT>
