JScience を使用して mathml ドキュメントを解析しようとしましたが、成功しませんでした。以下は私のコードです。
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();
}
}
ここからエラーが発生したため、これ以上何もできませんでした。以下は、スタック トレースです。

また、MathMLApplyElementImpl、MathMLDocumentImpl、または JSci.mathml パッケージの他のクラスを使用する方法を知っている人はいますか?
mathml ドキュメントを解析する方法に関するコードの例を提供できれば、それは素晴らしいことです。
どんなアイデアでも高く評価されます。ありがとう
