Harrell, At this stage, I have put together a set of routines based on the ExPat XML libraries to read LandXML into my own application. If it would be beneficial, I could put together a short documented Visual C++ example of how to read a given LandXML collection, say all CGPoints, into an Access table, using MFC DAO classes, the ExPat SDK, and C++. If this was a workable approach for you, it would provide a reasonable template for you to build on. If there is anyone else out there that could provide this example in terms of the LandXML SDK, I also believe that it would be a simple and valuable resource to the group. For those interested, I selected ExPat over Xerces as I wanted a simple efficient streaming parser that did not read the entire XML data set into a document using a document object model. The reason for this is that I regularly work with very large data sets, such as LIDAR, scanned data etc... and DOM would necessitate a copy of the data in memory to work. Using ExPat, I can stream LandXML data into my own compact database without the memory and performance overhead, albeit with PntRef resolution happening after input. The code is currently tightly coupled into my own application, but again, if it is of interest to any other members, I could provide illustrative examples of the techniques used.

I wanted to use Access, and have already dveloped a module that reads XML and builds linked tables. Access is supposed to be able to then save an XML file, but I've had problems making it work. If you have some luck with the SDK, I would like to know more about how to make it work.

Is there any documentation or tutorial information associated with this SDK, or is the intended usage to learn the SDK through investigating the browser samples? Alternatively, can anyone recommend an approach to implementing LandXML? We are currently working in Visual C++ 7.1, so the SDK seems like a good approach. Thanks and best regards, Shane MacLaughlin
