toMathMl(x^-1)

[GoogleCodeExporter]

public String getMathMl(String anExpression)
{
        StringWriter stringWriter = new StringWriter();
        new MathMLUtilities(new EvalEngine(),
        false).toMathML(anExpression, stringWriter);
        return stringWriter.toString();
}

getMathMl("x^-1"); or getMathMl("x^(-1)");

Produces:

<math>
    <msup>
        <mi>x</mi>
        <mo>(</mo>
        <mn>-1</mn>
        <mo>)</mo>
    </msup>
</math>

Expected is:
<math>
    <msup>
        <mi>x</mi>
        <mrow>
            <mo>(</mo>
            <mn>-1</mn>
            <mo>)</mo>
        </mrow>
    </msup>

</math>

Using:

commons-logging-1.1.1.jar
