thanks boris.
and for serialize a document after read it?
I  tryed with this code :

auto_ptr<ex::iso_10303_28> h (ex::iso_10303_28_("c:\\esempioifcxml.xml" ));
   
    xml_schema::namespace_infomap map;
    std::ofstream ofs ("c:\\test.xml");
    ::ex::iso_10303_28_(ofs, *h , map, "UTF-8");

but i get:
Unhandled exception at 0x00cf2aa6 in ifctest.exe: 0xC0000005: Access violation 
reading location 0x00000014.
size_type size() const
        {    // return length of sequence
        return (_Mysize);
        }
in xstring file.
may be that are the nillable  type?

and i see that when i parsing the xml in the output console of vs 2003 appear 
this exeception:

First-chance exception at 0x7c812afb (kernel32.dll) in ifctest.exe: Microsoft 
C++ exception: xercesc_3_1::TraverseSchema::ExceptionCodes @ 0x0013e210.

but all work fine
this is really all.
thanks again.

Hi Giuseppe,

Yes, you can do this using the DOMLSParser::parseWithContext() function.
Basically, you will need to do the following:

2. Set up your own XML-to-DOM parsing (see the 'multiroot' example for
   more information on how to do this).

3. Create an empty DOM document with the ifc prefix set.

4. Use the parseWithContext() function to parse your XML in the context
   of the document created on step 2.

4. Then, instead of calling the parsing  function, construct the root 
   element type directly:

   DOMElement* e = ... // iso_10303_28 element
   auto_ptr<ex::iso_10303_28> r (new ex::iso_10303_28 (*e));
