Question How to draw with XML edges ?

Hi, I'm working for few weeks now on a Adobe Animate converter for Unity, allows you to use source file and to play it.
Everything is fine, but I need to implement elements created with EaseJS on Unity, like this :

<Edge fillStyle1="1" strokeStyle="1" edges="!1375 2346|3228 2346!3228 2346|3228 3111!3228 3111|1375 3111!1375 3111|1375 2346"/>

I have an XMLNode to extract this data, and I already have a list of all my points.

My question is, how can I draw some elements using this edge and in runtime ?
I saw Vector Graphics but It's seems like It's only for already created SVG.
And for now on, we have no other solution, software architecture is the same since 10 years.

 

Definetly what I wanted to do, problem is that I'll have to formalize XML then convert it, and finally use the SVG package (example is pretty short, I have huge elements). I wanted to do all this steps in one part.
