I have an object to populate with xml. I think that I might use a contructor which accept this xml to build the object. But, is there a better design pattern to do it ? Is it to the object to handle all the xml parsing ?
Thank you !

No you should not send the xml to the constructor because you are coupling the model with deserilizing logic. You should create a class that handles the deserlization for you and return an instance. Why this is important might be unclear. But imagine in the future you may have the data coming from a database, you don’t want to pass the database connection to the constructor, do you? Instead you can create a different class that uses databases to generate an instance of your class.
