How do I post raw code into a Rich Text field without executing?

How do I post raw code into a Rich Text field without executing?

Currently, when I paste sample XML scripting into a records Rich Text field, the record updates with the tags removed. 
For example, I want to paste 

<name>
john
</name>

after updating the Rich Text field shows as

john


I don't want anything to be executed in this field. I've put in a Plain Text field as a workaround, but even those tags disappear when in a records view mode.

Please help! The whole purpose of us creating this application is to track XML protocol information. 

Thanks,
Brent
