How to use copySubTree in WDCopyService

[Amey-Mogare]

Hi,

I want to copy node elements from node-1 to node-2..

These two node has exactly same structure. These node have child nodes like following:-

Node 'Transaction' has two value attributes-> 'tid', 'tname' and a value node 'Combination' which has a value attribute 'desc'

Im able to copy value attributes tid, tname using copyCorresponding, but how do I copy child node elements ???

Regards,

Amey

Hi,

you can use copySubTree(source,target) of WDCopyService

Ya, i can use copySubTree()...

But I m not able to get how it works??

I read this from its documentation-->

-

---

copySubtree

public static void copySubtree(IWDNode source,

IWDNode target)

Copies all elements from to complete subtree of source to target. This is done by applying copyElements(IWDNode, IWDNode) to the nodes and then searching for equally named subnodes and recursively applying copySubtree to them.

Parameters:

source - The source node

target - The target node

Throws:

WDRuntimeException - if copyElements(IWDNode, IWDNode) fails for a node in the subtree.

-

I tried in several ways, but it is not working.. can u giv me any sample code to copy subtree???

Hi,

Did the above code worked?Or let me know in what way you have implemented it.

Hiiii Sudhir,

I guess there is something wrong in my implementation:-

Bcoz it is only copying 1st element's subtree..I tried putting it in loop too, but still not working..

public boolean BackUpTransaction( )

{

wdContext.nodeTransaction_1().invalidate();

try{

//Master = Transaction

//Target = Transaction_1

IPrivateView1.ITransaction_1Node TargetNode = wdContext.nodeTransaction_1();

IPrivateView1.ITransactionNode masterNode = wdContext.nodeTransaction();

int size = masterNode.size();

for (int i = 0; i < size; i++)

{

//Copying Transaction's value attributes

IPrivateView1.ITransactionElement masterElement = (IPrivateView1.ITransactionElement)wdContext.nodeTransaction().getElementAt(i);

IPrivateView1.ITransaction_1Node tr1node = wdContext.nodeTransaction_1();

IPrivateView1.ITransaction_1Element tr1element = tr1node.createTransaction_1Element();

WDCopyService.copyCorresponding(masterElement, tr1element);

tr1node.addElement(tr1element);

} //end of for

WDCopyService.copySubtree(wdContext.nodeTransaction().nodeCombination(),wdContext.nodeTransaction_1().nodeCombination_1());

} //end of try

catch(Exception e)

{

e.printStackTrace();

}

return true;

} //end of function

Pls suggest !!!

thank you..

Hi,

This should diffinetly work

WDCopyService.copyElements(wdContext.nodeMain(),wdContext.nodeMain_1());

for(int k=0;k<size;k++){

IMainElement ele=wdContext.nodeMain().getMainElementAt(k);

IMain_1Element ele1=wdContext.nodeMain_1().getMain_1ElementAt(k);

WDCopyService.copyElements(ele.nodeSub(),ele1.nodeSub_1());

}

Hi,

You can try this

WDCopyService.copyElements(wdContext.nodeTransaction(),wdContextNodeTransaction_1());

WDCopyService.copySubTree(wdContext.nodeTransaction().nodeCombination(),wdContext.nodeTransaction_1().nodeCombination());
