Thanks everyone for helping me this is a very good and helpful list. I was not serializing the node using DOMWriter after I removed children.

Here are some questions: 1) what is returned by the findNode method? The pointer to the DOMElement 'ContactType' or to its parent, 'Person1'? If the node returned is 'ContactType' you are removing the text node 'Partner', otherwise you are removing all the children of 'Person1', but in any case you are left with an empty element (e.g. in the first case <Person1><ContactType></ContactType><FirstName>y</FirstName>.... , in the second case <Person1></Person1>) 2) when you say "is still in the XML file", do you mean after you serialize back to disk using DOMWriter? Or are you expecting that by manipulating the DOM structure the XML file is automatically changed (it's not)?
