parsing: Test Failed at /home/runner/work/MathML.jl/MathML.jl/test/parse.jl:100
  Expression: isequal(MathML.parse_str(str), IfElse.ifelse(IfElse.ifelse(1 - t > 0, 1, 0) > 0.5, x * (y + a * z) * (1 - b * z) ^ -1, x * y))
   Evaluated: isequal(IfElse.ifelse(IfElse.ifelse(1.0 - t >= 0, 1, 0) > 0.5, x*(y + a*z)*((1.0 - (b*z))^-1), x*y), IfElse.ifelse(IfElse.ifelse(1 - t > 0, 1, 0) > 0.5, x*(y + a*z)*((1 - (b*z))^-1), x*y))

This is the first part

@test isequal(MathML.parse_str(str), 
  IfElse.ifelse(
    IfElse.ifelse(1. - t >= 0, 1, 0) > 0.5,
     x * (y + a * z) * ((1.0 - (b * z))^-1),
      x * y))

but then i hit

parsing: Error During Test at C:\Users\Anand\.julia\dev\MathML\test\parse.jl:235
  Test threw exception
  Expression: isequal(expand_derivatives(MathML.parse_str(str)), 12 * Num(Variable(:x)) ^ 2)

thanks again!
