Hi,

I am new to Julia and have a question regarding ModelingToolkit and SBML.

I imported an SBML file and converted the model into an ODESystem:

```
mdl = readSBML("Kok2020.xml", doc -> begin
set_level_and_version(3, 2)(doc)
convert_promotelocals_expandfuns(doc)
end)
odesys = ODESystem(mdl)
structural_simplify(odesys)
```

However, I am wondering if there is a function to obtain the equations,

parameters, variables and their values into a code format.

Namely, I want to add and change the equations for my own adjusted model.

Currently, the output is in Latex format and prevents me from easily

changing the equations.

So I want to obtain this, but than for the SBML model:

```
function SIRModel!(du, u, p, t)
# unpack p
β, γ = p
# unpack u
S, I, R = u
# define equations
dSdt = -β*I*S
dIdt = β*I*S - γ*I
dRdt = γ*I
du[1:3] = [dSdt, dIdt, dRdt]
nothing # return nothing
end
u0 = [0.9999, 0.0001, 0.]
p = [0.09, 0.008]
```

Can anyone help me with this?
