the class LaTeXMathObject method generateDOMTreeFromLaTeX.

    Writer out = null;
    DOMImplementation domImpl = GenericDOMImplementation.getDOMImplementation();
    String latexText;

    } else {
        latexText = text;
    }
    TeXFormula formula = new TeXFormula(latexText);
    TeXIcon icon = formula.createTeXIcon(TeXConstants.ALIGN_LEFT, 40);
    String svgNS = "http://www.w3.org/2000/svg";
    Document document = domImpl.createDocument(svgNS, "svg", null);
    // Create an instance of the SVG Generator.
    SVGGeneratorContext ctx = SVGGeneratorContext.createDefault(document);
