Bruce, > Calling for a new "r" element with string "data" on an empty tree You will need more than this. A DTD does not define a root element, take for instance Docbook where you can write a book as well as an article against the same DTD. So you need to specify at least the root element you want to use. There are some tools that generate an element content (oXygen does it too but it does not enter into choices). In the general case you will not know before hand what information will be needed to unambiguously generate an instance document. In your example you specify that some element must be present with some text content but this is not enough. A solution for the general case will be to walk through the DTD model starting from the desired root element and just ask the user when there is more than one possible path to follow. If your problem reduces to only one choice model and you know the root then specifying what element from the choice group must be present should be enough. Hope that helps, George ------------------------------------------------------------- George Cristian Bina mailto:george@o... <oXygen/> XML Editor - http://www.oxygenxml.com/ ----- Original Message ----- From: "Bruce Kulik" <bkulik@a...> To: <xml-dev@l...> Sent: Monday, January 12, 2004 4:41 PM Subject: Looking for tools to build valid XML file. > I am looking for a software module to help create valid XML given a > DTD and an element name and data.
