Program a parsing algorithm in C# for the following Mathml file:

$ax^2+bx+c$

It must be able to

Read a mathml.ml file

Parse the file

Store contents into any structure

Remove the brackets from a line

Read the tag in the line and know what it is doing. (In mathml, a tag means a specific operation done on the contents within it and so the algorithm must know what the tag is in order for it to correctly compute the equation that is written)

Output the basic equation

Perform a calculation with the contents

Only a few tags that are in the above file need to be implemented, and you may use external libraries if possible.
