[jdom-interest] How to get nextSibling, prevSibling, firstChild and lastChild in JDOM?

[Meghasyam Bokam]

Hi all,

    I am new to JDOM, and I see there are no methods to get nextSibling,
prevSibling, firstChild and lastChild of an ELEMENT. Can anybody help me
to write those specific methods which I can use in my application.

Thanks for the help.

Meghasyam.
