[xsd-users] Help me: Borland C++ Builder 2007 compiled program has unwanted prefix and all property values are missing.

[James Mei]

Hi

I have gone through the "Hello world" xsd tutorial with Borland C++ builder
2007. Everything works fine. I then proceed with generating more files from
other xsd.

..\xsd cxx-tree --generate-serialization --namespace-map
http://www.codesynthesis.com/xsd/SCL=SC_SCL *.xsd

The main program, which just parse the xml file and save it to another:

int main (int argc, char* argv[])
{
  try
  {
    using namespace SC_SCL;
    auto_ptr<SCL> h (SCL_ (argv[1], xml_schema::flags::dont_validate));

    ofstream outfile(argv[2], ios::out);
    SCL_(outfile, *h);

  }
  catch (const xml_schema::exception& e)
  {
    cerr << e << endl;
    return 1;
  }
}

During compilation, it prompts the follow error:

[BCC32 Error] SCL.cxx(273): E2093 'operator!' not implemented in type
'xsd::cxx::tree::optional<tCommunication>' for arguments of the same type

on the following line:

      if (n.name () == "Communication" && n.namespace_ () == "
http://www.codesynthesis.com/xsd/SCL")
      {
        ::std::auto_ptr< Communication_type > r (
          Communication_traits::create (i, f, this));

        if (!this->Communication_)
//<------------------------- error line
        {
          this->Communication_.set (r);
          continue;
        }
      }

I changed the above line to
        if (this->Communication_==NULL)
//<------------------------- changed
        {
          this->Communication_.set (r);
          continue;
        }

The program compiles and run. However, there are 2 unexpected results.

//Input XML file
<?xml version="1.0" encoding="utf-8"?>
<SCL xmlns="http://www.codesynthesis.com/xsd/SCL" xsi:schemaLocation="

          <p1:P type=""/>
          <p1:P type=""/>
        </p1:Address>
.............
Unexpected result 1: All the tags has an "p1:" prefix.

Unexpected result 2: It has no problem reading all the element names, but
all the properties are missing.

My questions

1. Did I do something wrong on modifying the line (if
(!this->Communication_) ) to cause this result ?
2. I recompiled the whole program and xerces-c-3.0.1 using MingW, the
unexpected result 2 is gone (all the property values appeared) but the
unexpected result 1 ("p1") still remains.
    May I know how can I correct the above two problems ?
