Iterating a DomTree

[Kohinoor]

Iam building a Dom Tree using the Xerces library. The Elements provided in it are like Dom_Document,Dom_Node etc.I would like to iterate throgh my Dom Tree in order to get a particular node & add new nodes there.It would be very kind if some one can send a source code regading this. I have a root element & Iam creating all the subsequent elements from this.

Thanks in advance
