I woudl like to be able to allow a user to read an XML file, and edit the contents of a certain Node.
I know how to parse the XML file using SimpleXML, and provide an edit link that would take the user to a form populated with the info for the chosen node, but I am not sure how i woudl go about saving the edited information to that node.
would i have to delete the node and then re-add it with the updated information, or is there a way to actually update the contents of an existing node?
