Very easy to solve issue with SimpleXML. What i'm doing wrong?

Question

I\'m working with Java and SimpleXML

I need to parse this XML file with SimpleXML:

Answer 1

You must put required=false on the ArrayList of areas, some of the Pages of the XML doesn't have Areas

    @Root
public class Page {
    @Attribute
    String src;
    @Attribute
    String id;
    @Attribute
    String thumbnail;
    @ElementList (required=false)
    public ArrayList<Area> areas;
}

Answer 2

That errors appear when I had errors in XML file (like unended tag). For someone who have the same problem and came to this post.
