[xsd-users] unable to write new fields to XML file

[Aciel Eshky]

Hi Boris,

Thanks for your response. I was able to resolve the problem by removing the
namespace from the xsd file. I am now able to write the results to an
output xml file (which looks like the input but with the results appended
to it).

If possible, I'd still like to understand why it wasn't working properly
before. In my xsd options, I was previously using the namespace mapping and
it was working properly as far as input xml files are concered. Perhaps I
was missing something similar for the output?

Here is my c++ code.

xml_schema::namespace_infomap map;
map[""].name = "ourwebsite";
map[""].schema = "ourschemaname.xsd";

char* ptr_xml_file_out = "output_with_results.xml";
std::ofstream ofs(ptr_xml_file_out);

QBAS_(ofs, *q, map);

Any useful insights would be appreciated.

Thanks!
Aciel
