Parsing Image Location - In Constructor Or Where

I'm working on a small game, and I have a quick question about parsing a file. Basically, I have a utility method, which loads an XML file containing the details of all the items for the level, and then pulls the info and passes it to the Item constructor.

A snippet of the XML file is:

<item key = "Weapon1" name = "Sword" description = "A basic sword... etc" hint = "picked up SWORD" givesPlayer = "basicSword:1" bitmap = "5,5" />

And a snippet of the class is:

public class Item extends Entity {

String name;
private String description;
private String hint;
private Map<String, Integer> givesPlayer = new HashMap<>();
private boolean pickedUp;

[Code] ....

The XML file contains this field:
bitmap = "5,5"

which basically specifies a column and row where it should grab an image from, located elsewhere.

My question is this: Should I parse this "5,5" in my utility method and pass the image(s) to the constructor(// B Consturctor), or is it ok to pass the location as a String and parse it in the Constructor( // A Constructor) ?
