Creating Pretty JAXB Classes

I have used JAXB to parse XML in the past and created my own simple classes for it. These were POJOs like

public class Foo {

    @XmlAttribute
    public String someAttribute;

    public String someElement;

    public Bar bar;
}

      

        
        
        
      

    

Now I want to write a tool that needs to parse data from a very complex xml structure and I would like not to write it myself. I tried using xjc to generate the classes, but they look completely different from my example above:

@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "RulesElementType", propOrder = { "content" })
public class RulesElementType {

    @XmlElementRefs({ @XmlElementRef(name = "flavor2", type = JAXBElement.class, required = false),
            @XmlElementRef(name = "specific", type = JAXBElement.class, required = false),
            @XmlElementRef(name = "category2", type = JAXBElement.class, required = false),
            @XmlElementRef(name = "flavor1", type = JAXBElement.class, required = false),
            @XmlElementRef(name = "print-prereqs", type = JAXBElement.class, required = false),
            @XmlElementRef(name = "prereqs2", type = JAXBElement.class, required = false),
            @XmlElementRef(name = "rules", type = JAXBElement.class, required = false),
            @XmlElementRef(name = "prereqs1", type = JAXBElement.class, required = false) })
    @XmlMixed
    protected List<Serializable> content;
    @XmlAttribute(name = "name")
    protected String name;
    @XmlAttribute(name = "type1")
    protected String type1;
    @XmlAttribute(name = "internal-id")
    protected String internalId;
    @XmlAttribute(name = "source")
    protected String source;
    @XmlAttribute(name = "revision-date")
    protected String revisionDate;

    /* getters and setters omitted */

    @XmlAccessorType(XmlAccessType.FIELD)
    @XmlType(name = "", propOrder = { "value" })
    public static class Category2 {

        @XmlValue
        protected String value;
        @XmlAttribute(name = "name")
        protected String name;

        /* getters and setters omitted */

    }

    /* additional class definitions omitted */

}

      

        
        
        
      

    

To get an element named "flavor1" I need to find the "content" attribute for a JAXBElement named "flavor1", which I find terribly awkward. What I would like to do is something like:

String flavor1 = rulesElement.getFlavor1();

      

        
        
        
      

    

Is there a way to accomplish this with xjc or some other tool?

Edit: The complexType for RulesElementType from my xsd:

  <xs:complexType name="RulesElementType" mixed="true">
    <xs:choice maxOccurs="unbounded" minOccurs="0">
      <xs:element name="category2">
        <xs:complexType>

          </xs:choice>
          <xs:attribute type="xs:string" name="name" use="optional"/>

      </xs:element>

The XML file looks somewhat similar to this .

I am using XMLBeans to generate xsd. Since the XML file I am reading is about 680K lines, manually generating the XSD is not an option.
