Removing XML nodes From XML Using JaVa

Question

I have a XML document

<ns1:Product>
<ns1:ProductDetails>
    <ns1:StationID>1</ns1:StationID>
    <ns1:ProductGroup>1</ns1:ProductGroup>
    <ns1:AccountCode>1</ns1:AccountCode>
    <ns1:Amount>1345</ns1:Amount>
    </ns1:ProductDetails>
<ns1:ProductDetails>
    <ns1:StationID>1</ns1:StationID>
    <ns1:ProductGroup>1</ns1:ProductGroup>
    <ns1:AccountCode>2</ns1:AccountCode>
    <ns1:Amount>35471</ns1:Amount>
    </ns1:ProductDetails>
<ns1:ProductDetails>
    <ns1:StationID>1</ns1:StationID>
    <ns1:ProductGroup>1</ns1:ProductGroup>
    <ns1:AccountCode>3</ns1:AccountCode>
    <ns1:Amount>31897</ns1:Amount>
    </ns1:ProductDetails>
<ns1:ProductDetails>
    <ns1:StationID>1</ns1:StationID>
    <ns1:ProductGroup>1</ns1:ProductGroup>
    <ns1:AccountCode>4</ns1:AccountCode>
    <ns1:Amount>143647</ns1:Amount>
    </ns1:ProductDetails>
<ns1:ProductDetails>
    <ns1:StationID>1</ns1:StationID>
    <ns1:ProductGroup>1</ns1:ProductGroup>
    <ns1:AccountCode>5</ns1:AccountCode>
    <ns1:Amount>34531</ns1:Amount>
</ns1:ProductDetails>

I have able to count the total number of records using Java as 5. I have few requirement in which i have to remove some records before processing further. Say for example I have to remove 3rd and 5th ProductDetails from the XML

Base on the record Position details I have to remove the 2 record

Final Output

<ns1:Product>
<ns1:ProductDetails>
    <ns1:StationID>1</ns1:StationID>
    <ns1:ProductGroup>1</ns1:ProductGroup>
    <ns1:AccountCode>1</ns1:AccountCode>
    <ns1:Amount>1345</ns1:Amount>
</ns1:ProductDetails>
<ns1:ProductDetails>
    <ns1:StationID>1</ns1:StationID>
    <ns1:ProductGroup>1</ns1:ProductGroup>
    <ns1:AccountCode>2</ns1:AccountCode>
    <ns1:Amount>35471</ns1:Amount>
</ns1:ProductDetails>
<ns1:ProductDetails>
    <ns1:StationID>1</ns1:StationID>
    <ns1:ProductGroup>1</ns1:ProductGroup>
    <ns1:AccountCode>4</ns1:AccountCode>
    <ns1:Amount>143647</ns1:Amount>
    </ns1:ProductDetails>
 </ns1:Product>

Can some one please help be to active this in Java Code!

Show us what have you tried and where did you stuck and we'll help you to move on. I'd use DOM to create a document object model and then you can add/remove nodes in model. Then you can write DOM to file again. There is a tutorial googled right now: http://tutorials.jenkov.com/java-xml/dom.html — Piotr Gwiazda, Aug 16 '12 at 11:55

Use the standard library. I'm sorry but you've got to read the Java Tutorial :

"To remove a node, you use its parent Node's removeChild method."
