The XML DOM doesn't store the file position. There is a filepos property but this only applies to parsing errors. Depending on why you need to know the file position, I guess the best solution, other then reading the XML file character by character, would be to use SAX http://msdn.microsoft.com/library/en-us/xmlsdk/htm/sax_devgd_overview_0jef.asp. The ISAXLocator interface http://msdn.microsoft.com/library/en-us/xmlsdk/htm/sax_isaxlocator_7kx1.asp provides both columnNumber and LineNumber properties.

Why the grade C? Did this not answer your question? If you needed more information you should say so. I now have a grade C against my name just for taking the time to answer your question. Thanks.

sorry i'm not familiar with experts exchange conventions, i did not think that giving a C grade was almost like a blame...
I gave a C grade because your answer did not really learn anything to me; i knew about SAX but it seems to me a very complicated solution. But perhaps there is no other way.
If there is a way i can modify the grade, let me know.
