Frank, Actually I modified my code, now I drop all the nodes that starts with <? or <! at the beginning of my file so that I only have the "main" node (<svg in my case) before parsing the buffer with CPLParseXMLString. Maybe not the best way to do the job but it works.

Aurel, The code looks ok except that it misses the siblings of the root node. In a case like the above file the "a" element will be a sibling of the <?xml...> node, not a child. There are numerous examples of code for recursing and searching the XML document in gdal/port/cpl_minixml.cpp. Best regards, -- ---------------------------------------+------------------------------------ -- I set the clouds in motion - turn up | Frank Warmerdam, [EMAIL PROTECTED] light and sound - activate the windows | http://pobox.com/~warmerdam and watch the world go round - Rush | Geospatial Programmer for Rent _______________________________________________ gdal-dev mailing list gdal-dev@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/gdal-dev
