I want to use Simple XML to deserialize the following XML into a POJO:

<shippingInfo>
 <shippingServiceCost currencyId="USD">9.8</shippingServiceCost>
 <shippingType>Flat</shippingType>
 <shipToLocations>Worldwide</shipToLocations>
 <expeditedShipping>true</expeditedShipping>
 <oneDayShippingAvailable>false</oneDayShippingAvailable>
 <handlingTime>3</handlingTime>
</shippingInfo>

I have created the following class to do so. However, I'm having trouble in that the currencyId attribute isn't being properly deserialized.

@Root(name = "shippingInfo")
public class ShippingInfo 

 @Element(name = "shippingServiceCost", required = false)
 private BigDecimal shippingServiceCost;

 @Attribute(name = "currencyId", required = false)
 private String currencyId;

 @Element(name = "shippingType", required = false)
 private String shippingType;

 @Element(name = "shipToLocations" ,required = false)
 private String shipToLocations;

 @Element(name = "expeditedShipping", required = false)
 private Boolean expeditedShipping;

 @Element(name = "oneDayShippingAvailable", required = false)
 private Boolean oneDayShippingAvailable;

 @Element(name = "handlingTime", required = false)
 private Integer handlingTime;

 // Getters & Setters

 public BigDecimal getShippingServiceCost() 
 return shippingServiceCost;
 

 public void setShippingServiceCost(BigDecimal shippingServiceCost) 
 this.shippingServiceCost = shippingServiceCost;
 

 public String getCurrencyId() 
 return currencyId;
 

 public void setCurrencyId(String currencyId) 
 this.currencyId = currencyId;
 

 public String getShippingType() 
 return shippingType;
 

 public void setShippingType(String shippingType) 
 this.shippingType = shippingType;
 

 public String getShipToLocations() 
 return shipToLocations;
 

 public void setShipToLocations(String shipToLocations) 
 this.shipToLocations = shipToLocations;
 

 public Boolean isExpeditedShipping() 
 return expeditedShipping;
 

 public void setExpeditedShipping(Boolean bool) 
 this.expeditedShipping = bool;
 

 public Boolean isOneDayShippingAvailable() 
 return oneDayShippingAvailable;
 

 public void setOneDayShippingAvailable(Boolean bool) 
 this.oneDayShippingAvailable = bool;
 

 public Integer getHandlingTime() 
 return handlingTime;
 

 public void setHandlingTime(Integer days) 
 this.handlingTime = days;
 

I would expect the value of currencyId to be "USD" after deserializing, but I'm getting null. All the element values appear to deserialize properly. Does anyone have a suggestion on how to fix this?

Moreover, in a case such as the following instance:

<sellingStatus>
 <currentPrice currencyId="USD">125.0</currentPrice>
 <convertedCurrentPrice currencyId="USD">125.0</convertedCurrentPrice>
 <bidCount>2</bidCount>
 <sellingState>EndedWithSales</sellingState>
</sellingStatus>

Where there are two attributes named currencyId on two distinct elements, how can I go about deserializing these into separate fields? I have created a similar SellingStatus class but am unsure how to distinguish between the currencyId attributes.

Thank you!

Edit: Per suggestions I tried adding a custom ShippingServiceCost class to ShippingInfo as follows:

@Element(name = "shippingServiceCost", required = false)
 private ShippingServiceCost shippingServiceCost;

Which in turn looks like this:

public class ShippingServiceCost 

 @Element(name = "shippingServiceCost", required = false)
 private BigDecimal shippingServiceCost;

 @Attribute(name = "currencyId", required = false)
 private String currencyId;

 // getters and setters

But when I try to access both the shippingServiceCost field and the currencyId field, I get null in every instance (even though I know there is data). Any suggestions are greatly appreciated.

For the above code, SimpleXML expects the currencyId to be present as <shippingInfo currencyId="USD">.

So to solve it, you need to create another class called ShippingServiceCost which will contain the currencyId attribute and the BigDecimal
This will also solve your second query. You can do it by creating two classes CurrentPrice and ConvertedCurrentPrice which will contain the currencyId attribute.
