>I would like to know if there is any mapping between the "DOM tree" and the XML file. Just that "document order" in the XML file corresponds to a depth-first tree-walk of the DOM. (With the exception of Attrs; the XML spec says they are unordered and the DOM is not required to keep them in any particular order.) > What can I do to know the physical position of an XML content node in the XML file? If you mean line number and/or character offset -- the DOM doesn't define any way to obtain that information. Some DOM implementations may have custom features which can answer this question, but code using those features will not be portable. Generally, XML assumes that nobody but the parser cares about that level of detail; once the information has been read into a DOM, you want to work in terms of its structure and information content rather than exactly how it was written in the file. If your question is "how can I generate useful error messages" -- the best solution I've seen is to have your message include an XPath that indicates where the error occurred. ______________________________________ Joe Kesselman / IBM Research
