I want the Country class to store the "ISO_3166-1_Alpha-2_Code" code. The code currently gets back the "ISO_3166-1_Numeric-3_Code" code. Can't figure out how to tweak the Country class to get the specific attribute I want.

XML:

<?xml version='1.0' encoding='UTF-8'?>
<wd:Message_Event_Configuration">
 <wd:Message_Event_Configuration_Data>
 <wd:Country_Reference wd:Descriptor="Saint Martin">
 <wd:ID wd:type="WID">66b7082a21e510000961bb6d82b5002a</wd:ID>
 <wd:ID wd:type="ISO_3166-1_Alpha-2_Code">MF</wd:ID>
 <wd:ID wd:type="ISO_3166-1_Alpha-3_Code">MAF</wd:ID>
 <wd:ID wd:type="ISO_3166-1_Numeric-3_Code">663</wd:ID>
 </wd:Country_Reference>
 <wd:Country_Reference wd:Descriptor="Saint Barthelemy">
 <wd:ID wd:type="WID">881527f6cec910000ba81e8dccf61127</wd:ID>
 <wd:ID wd:type="ISO_3166-1_Alpha-2_Code">BL</wd:ID>
 <wd:ID wd:type="ISO_3166-1_Alpha-3_Code">BLM</wd:ID>
 <wd:ID wd:type="ISO_3166-1_Numeric-3_Code">652</wd:ID>
 </wd:Country_Reference>
 </wd:Message_Event_Configuration_Data>
</wd:Message_Event_Configuration>

Country List:

@XmlRootElement(name = "Message_Event_Configuration")
@XmlAccessorType(XmlAccessType.FIELD)
public class Countries 

 @XmlElementWrapper(name = "Message_Event_Configuration_Data")
 @XmlElement(name = "Country_Reference")

 private List<Country> countries = new ArrayList<Country>();

 public List<Country> getCountries() 
 return countries;
 

 public void setCountries(List<Country> countries) 
 this.countries = countries;
 

Country:

@XmlAccessorType(XmlAccessType.FIELD)
@XmlRootElement(name = "Country_Reference")
public class Country 

 @XmlElement(name = "ID")
 private String isoCode;

 public Country() 
 

 public Country(String isoCode) 
 this.isoCode = isoCode;
 

 @XmlAttribute(name = "ISO_3166-1_Alpha-2_Code")
 public String getISOCode() 
 return isoCode;
 

 public void setISOCode(String isoCode) 
 this.isoCode = isoCode;
 

The <Country_Reference> XML element contains the ISO codes in a rather
sophisticated way within several <wd:ID> XML elements.
It is therefore much too simple to model them as a Java String property.

Instead, you need to model the Java-structure with more similarity to the XML-structure.

The sequence of XML elements <wd:ID> can be modeled by a property List<ID> idList
which needs to be annotated by@XmlElement(name="ID") .

The XML attribute wd:Descriptor="...." can be modeled by a property String descriptor
which needs to be annotated by @XmlAttribute(name="Descriptor").

For your convenience you can add an all-arguments-constructor and some methods for getting
the WID and ISO codes from the List<ID>.

@XmlAccessorType(XmlAccessType.FIELD)
public class Country 

 @XmlAttribute(name = "Descriptor")
 private String descriptor;

 @XmlElement(name = "ID")
 private List<ID> idList;

 public Country() 
 

 public Country(String descriptor, String wid, String isoAlpha2Code, String isoAlpha3Code, String isoNumeric3Code) 
 this.descriptor = descriptor;
 idList = new ArrayList<>();
 idList.add(new ID("WID", wid));
 idList.add(new ID("ISO_3166-1_Alpha-2_Code", isoAlpha2Code));
 idList.add(new ID("ISO_3166-1_Alpha-3_Code", isoAlpha3Code));
 idList.add(new ID("ISO_3166-1_Numeric-3_Code", isoNumeric3Code));
 

 public String getWid() 
 return getIdByType("WID");
 

 public String getIsoAlpha2Code() 
 return getIdByType("ISO_3166-1_Alpha-2_Code");
 

 public String getIsoAlpha3Code() 
 return getIdByType("ISO_3166-1_Alpha-3_Code");
 

 public String getIsoNumeric3Code() 
 return getIdByType("ISO_3166-1_Numeric-3_Code");
 

 private String getIdByType(String idType) 
 for (ID id : idList) 
 if (id.getType().equals(idType))
 return id.getValue();
 
 return null;
 

The XML elements <wd:ID> are quite complex. Therefore we need a separate POJO class for modeling them.
Let's call the class ID.

The XML text between <wd:ID ..> and </wd:ID> is modeled by the property String value
which needs to be annotated by @XmlValue.

The XML attribute wd:type="..." is modeled by the property String type
which needs to be annotated by @XmlAttribute.

For convenient use by the class Country above, an all-arguments-constructor is added.

@XmlAccessorType(XmlAccessType.FIELD)
public class ID 

 @XmlAttribute
 private String type;

 @XmlValue
 private String value;

 public ID() 
 

 public ID(String type, String value) 
 this.type = type;
 this.value = value;
 

 // public getters and setters (omitted here fro brevity)

and confirms that the unmarshalling of your XML example works correctly:
