XSL Conversion Issue // Superscript/subscript and other texts text's are ignored

[dasanb]

Due to the conversion issue #9 in the ruby script, I used the XSL library lib/transform.xsl to transform the outputs generated using jure/mathtype, the transformation looks good but

1. it ignores the superscript and subscript text and produces the empty elements in MathML output.

2. In the second equation the square root is ignored

MathML from XSL

        <mn>&#x0028;</mn>
        <mi>&#x0078;</mi>
        <msup>
          <mrow> 
          </mrow>
        </msup>
        <mo>&#x002B;</mo>
