Hello Bergos
With a RDF/XML content that contains ref:ParseType="Literal" , Can you suggest the right technique for parsing RDF/XML that contains ref:ParseType="Literal"?
With my test data as posted on this message, I try to parse it by accessing "Gain" value with data.object.nominalValue.lastChild.nodeValue Is it the right technique with your library design?
I cannot find supported documentation on this issue. If you have suggestion , please advise. I posted complete of code, test data, and console output as follow.
Thank you ,

// My code
theRdfXmlParser.parse(sample_simulinkblocks_in_rdf, function(graph) {
graph.forEach(function(data){
console.log('------------- graph.forEach -----------');
console.log('subject toString(): ' + data.subject.toString());
console.log('predicate toString(): ' + data.predicate.toString());
console.log('object toString(): ' + data.object.toString());
console.log('subject nominalValue: ' + data.subject.nominalValue);
console.log('predicate nominalValue: ' + data.predicate.nominalValue);
console.log('object nominalValue: ' + data.object.nominalValue);
if (typeof data.object.nominalValue == 'string' || data.object.nominalValue instanceof String) {
// Do nothing
console.log('data.object.nominalValue is string"');
}else{
console.log('Detected rdf:parseType="Literal"');
console.log(data.object.nominalValue); // <--- It will print array in console
// I try to access "Gain" value with data.object.nominalValue.lastChild.nodeValue
}
});
});
