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

[James Mei]

Hi Boris

Thanks for the fast reply. Really appreciate your help.

After I changed the libxsd/xsd/cxx/tree/containers.hxx, the program compiles
and run in BCB 2007. However it still does not read the properties value and
has "p1" prefix in front of every tag.

Here is the updated main program:

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

    xml_schema::namespace_infomap map;
    map[""].name = "http://www.codesynthesis.com/xsd/SCL";
    map[""].schema = "SCL.xsd";

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

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

input XML

<?xml version="1.0" encoding="utf-8"?>
<SCL xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="
http://www.w3.org/2001/XMLSchema" xmlns="http://www.iec.ch/61850/2003/SCL"
xsi:schemaLocation="http://www.iec.ch/61850/2003/SCL SCL.xsd">
  <Header id="SEL"/>
  <Communication>
    <SubNetwork name="NONE">
      <ConnectedAP iedName="SEL_421" apName="P1">
        <Address>
          <P type="OSI-AP-Title">1,1,1,999,1</P>
          <P type="OSI-AE-Qualifier">12</P>
          <P type="OSI-PSEL">00000001</P>
          <P type="OSI-SSEL">0001</P>
          <P type="OSI-TSEL">0001</P>
          <P type="IP">209.254.235.118</P>
        </Address>
..................

Output XML
<?xml version="1.0" encoding="UTF-8" standalone="no" ?>
<p1:SCL xmlns:p1="http://www.iec.ch/61850/2003/SCL" xmlns="
http://www.codesynthesis.com/xsd/SCL" xmlns:xsi="
http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="
http://www.codesynthesis.com/xsd/SCL SCL.xsd">

  <p1:Header id="" nameStructure="" revision=""/>

  <p1:Communication>
    <p1:SubNetwork name="">
      <p1:ConnectedAP apName="" iedName="">
        <p1:Address>
          <p1:P type=""/>
          <p1:P type=""/>
          <p1:P type=""/>
          <p1:P type=""/>
          <p1:P type=""/>
          <p1:P type=""/>
        </p1:Address>

Again, the "p1" prefix is still there and all the properties values are
missing.

Best Regards
James
