Hello, I would like to use the Boost XML structure. Is the package within the SVN compatible under OSX, Linux and MS Windows? I'm using it at the moment under OSX, but I must use the code later under Linux and Windows. Under OSX I use the libxml2 Library, but in the boost/xml/dom/io.hpp I get an compile error on line 36 "xmlSaveCtxt *ctx = xmlSaveToIO (detail::stream_write_callback, detail::stream_close_callback, sb, enc, XML_SAVE_FORMAT);" the XML_SAVE_FORMAT isn't defined (message: not declared in this scope). My problem is at this time, that I must parse XML data of a stream objekt on-fly and extract some nodes (and this with a cross-plattform library). Is this the correct way to do the parsing with Boost XML? Thanks Phil
