getting nested xml tags of the same name

[Ervin Loh]

i'm using jaxp from sun for my xml parsing. i have problems obtaining the value of a tag with duplicate names but residing on different level. e.g.,
<Customer>
<CustomerID>Experts Exchange</CustomerID>
<Order>
<Item>1</Item>
<CurrencyCode>USD</CurrencyCode>
<Amount>94</Amount>
<Order>
<CreditLimit>
<CurrencyCode>USD</CurrencyCode>
<Amount>4000</Amount>
</CreditLimit>
<Product>
<ProductItem>
<ProductName>Peanuts</ProductName>
<CurrencyCode>USD</CurrencyCode>
<Amount>4.99</Amount>
</ProductItem>
<ProductItem>
<ProductName>Sweets</ProductName>
<CurrencyCode>USD</CurrencyCode>
<Amount>15.99</Amount>
</ProductItem>
</Product>
suppose now i want to obtain the value of 'CurrencyCode' at different levels using DOM, how do i actually code for it? any sample codes are appreciated.

You can call the getElementsByTagName(java.lang.String tagname) method on Document object returned by the parser.
The method takes the tag name as the argument and returns a NodeList of all the Elements with the given tag name in the order in which they are encountered in a preorder traversal of the Document tree.
In your case, the argument will be "CurrencyCode".
Once you have the list, you can iterate through it, retrieve individual objects and process them.
Hope that helps!
