java - How to read the same xml tag using Stax parser -

<product> <supplydetail> <price>  <pricetypecode>01</pricetypecode>   <discountcoded>     <discountcodetype>02</discountcodetype>                    <discountcodetypename>lsi</discountcodetypename>     <discountcode>25</discountcode></discountcoded>  <priceamount>29.95</priceamount>  <currencycode>inr</currencycode> </price> </supplydetail> <supplydetail> <price>   <pricetypecode>08</pricetypecode>   <priceamount>14.32</priceamount>   <currencycode>inr</currencycode> </price> </supplydetail> </product> 

i want output

pricetypecode  : 01 priceamount  : 29.95 currencycode  : inr  pricetypecode : 08 price amount  : 14.32 currencycode  : inr

my pojo class. specificationbook.java

  public class specificationbook {  @getter @setter public string recordreference; @getter @setter public string titletext; @getter @setter public string imprintname; @getter @setter public string publishername; @getter @setter public string illustrationdesc; @getter @setter public string noofpages; @getter @setter public string pricetypecode; @getter @setter public int book_id;    @getter @setter public string editionversionnumber; @getter @setter public string recordreference1; @getter @setter public string recordreference2; @getter @setter public string recordreference3  ; @getter @setter public string pricetypecodechar; @getter @setter public string priceamount; @getter @setter public string priceamount2; @getter @setter public string currencycode; @getter @setter public string currencycode1; } 

i tried value supply detail <price> tag values. while run code. got values second <supplydetail> tag values only.

while run code in machine got output as

the price type code 08=08 price amount 08 is:14.83 currency code 08 is:inr  price typecodechar 01 is:null price amount 01 is:null currency code 01 is:null 

you never invoke setters pricetypecodechar, priceamount2 , currencycode1 - print null.

additionally, specificationbook created each product tag , added result list when encounter product's close tag. way values overwritten every new price.

the easiest way fix change specificationbook class, remove price specific fields , add list of price objects.

class specificationbook {     // other fields     list<price> prices; } 

where price class like

class price {     string priceamount;     string pricetypecode;     string currencycode; } 

you check start-tags price, add details and, when encounter price end-tag, add specificationbook's prices.
