position offsets in xerces

[Marc Seldin]

I’m struggling with a frustrating problem. Ultimately I’m working on an NLP application where I need to locate the file offset positions where elements occur. I can’t find a way to get this in DOM mode, so I turned to SAX parsing. My thought was to create a DOM object via a SAX handler and use the setuserdata method to store the node offsets as these are discovered.   However, only one kind of object, a DOMLocator, seems to provide this information. In contrast, the only type of object that seems available in SAX parsing (as far as I’ve discovered) is a straight Locator object, which is unrelated to the DOMLocator in any way.   My questions are thus: 1)       Is there a better way to get these offset then going through SAX parsing? 2)       Even using SAX parsing, how do I involve the DOMLocator class? Or am I on the wrong track completely there?   Thanks in advance.       _______________________________________________ Marc Seldin Scientist BBN Technologies 410-290-6141
