Я пытался разобрать документ mathml, используя JScience, но безуспешно.Ниже приведен мой кусок кода.
import JSci.io.*;
import JSci.mathml.*;
.
.
public class ParsingMathML(){
try {
....
//inputFile is an xml file containing mathml code
InputSource file = new InputSource(new FileReader(inputFile));
MathMLParser parser = new MathMLParser();
parser.parse(file);
Object[] parseList = parser.translateToJSciObjects();
}catch (Exception e) {
e.printStackTrace();
}
}
Я получил ошибку здесь, поэтому я не мог ничего делать дальше.Ниже приводится StackTrace:

Кроме того, есть ли у кого-нибудь идеи, как использовать MathMLApplyElementImpl, MathMLDocumentImpl или любые другие классы из пакета JSci.mathml?
Будет здорово, если выможет предоставить некоторый пример кода о том, как анализировать документ mathml.
Любая идея будет высоко оценена.Спасибо
