Error while running latex with a tex file created using XSLTML 2.1.2

Question

I am creating a PDF with equation in the below way

Mathml.xml > XSLTML 2.1.2 > pdflatex

that is I am having an xml file with mathml equations and I am creating a tex file out of it using XSLTML 2.1.2 (XSLT file) and which gives an output of a .tex file, the tex file will be used to create a PDF by compiling it as pdflatex *.tex

but while doing that, there is an error comes in

My mathml file :

\end{equation*}

\end{document}

I am new to MathML and Tex, so anyone suggest a solution for this

Thank you

Pandoc also reads MathML (you can just pretend it's an HTML file):

pandoc -f html -t latex Mathml.xml

If you have LaTeX installed, you can even get a PDF directly:

pandoc -f html Mathml.xml -o output.pdf
