XPath, replace XML part in BPEL variable.

Question

Hi.
Let's say i have a variable in BPEL which is filled with data :
<group id="id1">
<element name="name1" selected="N"/>
<element name="name2" selected="N"/>
<element name="name2" selected="N"/>
<element name="name2" selected="N"/>
</group>
<group id="id2">
<element name="name1" selected="N"/>
<element name="name2" selected="N"/>
<element name="name2" selected="N"/>
<element name="name2" selected="N"/>
</group>
<group id="id3">
<element name="name1" selected="N"/>
<element name="name2" selected="N"/>
<element name="name2" selected="N"/>
<element name="name2" selected="N"/>
</group>
Im sending one of the groups to my web app which changes the data and returns 1 group.
<group id="id2">
<element name="name1" selected="N"/>
<element name="name2" selected="Y"/>
<element name="name2" selected="Y"/>
<element name="name2" selected="Y"/>
</group>
And now i have to update the variable in BPEL becouse it is not up to date. So i want to replace my group with id="id2" with the one i received from my web app.
I dont know how to do it :( can somebody guide me through it ? A simple copy operation doesnt work :(
Thanks for help in advance.

Thx, i already managed to do it. Im using Java Embedded :
Element input = (Element)getVariableData("pageRequestInput", "payload", "/client:ConfiguratorWizardProcessRequest/client:productGroup");
Element output= (Element)getVariableData("ProductCatalogInstance", "payload", "/client:KP");
Node adoptedInput = output.getOwnerDocument().importNode( input, true );
NodeList list = output.getChildNodes();
Node oldChild = output;
for(int i = 0; i < list.getLength(); i++){
if ( list.item( i ).hasAttributes() ) {
addAuditTrailEntry( list.item( i ).getNodeName() );
NamedNodeMap attributes = list.item( i ).getAttributes();
for( int j = 0; j < attributes.getLength(); j++){
if( attributes.item( j ).getNodeName().equals( "id" ) ){
if( attributes.item( j ).getNodeValue().equals( input.getAttribute( "id" ))){
oldChild = list.item( i );
break;
}
