I have to use the JDOM java api.  Can anyone point me to some examples or let me know how to change the following xml using JDOM?

I have to locate the correct entity (e.g., entity = 50).  If there isn't a value attribute, I have to create a value attribute set to some numeric number.  If there is a value attribute, I have to change its number.
        <entity id="45" value="234" />
        <entity id="50" />
