The version of JSBML that I am testing has a problem with the SBML namespace in math elements. Here is a test program, along with a test file containing a math element, and the output of the program.

JSBML reads the math element, but it doesn't keep the SBML namespace, at least at the level of the math element. Coding would be easier if was kept. Is there a workaround for this?

public class ConstraintMathMLTest
{
public static void main( String[] args )
{
try
{
File f = null;
SBMLDocument document = null;
try
{
f = new File( "E:\\testsbml\\testConstraintMathML.sbml");
document = SBMLReader.read( f);
Model m = document.getModel( );
ListOf<Constraint> cList = m.getListOfConstraints( );
Iterator<Constraint> cIt = cList.iterator( );
while ( cIt.hasNext( ) )
{
Constraint c = (Constraint) cIt.next( );
System.out.println( c.getMathMLString( ) );
}
}
catch( java.util.EmptyStackException e )
{
throw new IOException( e.getMessage( ) );
}
catch( XMLStreamException x )
{
throw new IOException( x.getMessage( ) );
}
}
catch( Exception ex )
{
ex.printStackTrace( );
}
System.out.println( "Done" );
}
}
