Using importNode to add 2 XML docs. Please see and Advise

[luthriaajay]

An extremely tricky and challenging code.

I have been able to add 2 XML documents together
using importNode().

 
xmlDoc1
----------
 
<?xml version="1.0" encoding="UTF-8"?>
<i:Interest xmlns:i="common">
<i:Details xsi.type="i:vanilla.details.stock">
  <i:Strategy xsi.type="strategies:call">
     <strategies.Expiry>2009-12-01</strategies.Expiry>
  </i:Strategy>
<i:Ref/>
</i:Details>
</i:Interest>
 
xmlDoc2
------------
<?xml version="1.0" encoding="UTF-8"?>
<i:Underlying value="KGF">
<common:Currency>GBP</common:Currency>
</i:Underlying>
 
My Java Code to append them together
-----------------------------------------------------
 
NodeList list = xmlDoc2.getChildNodes();
 
for (int i=0; i< list .getLength(); i++) {
 
     Element element = (Element)list.item(i);
     Node dup = xmlDoc1.importNode(element, true);
 
     xmlDoc1.getDocumentElement().appendChild(dup);
}
 
Output:
------    
<?xml version="1.0" encoding="UTF-8"?>
<i:Interest xmlns:i="common">
<i:Details xsi.type="i:vanilla.details.stock">
     <strategies.Description>Call</strategies.Description>
     <strategies.Expiry>2009-12-01</strategies.Expiry>
   </i:Strategy>
<i:Ref/>
</i:Details>
<i:Underlying value="KGF">
<common:Currency>GBP</common:Currency>
</i:Underlying>
</i:Interest>    
 
 
 

Query:
I would like to add the 2nd XML Document after element <i:Ref> . How to do this? I dont want the 2nd XML doc after <i:details> but before it.
Please help.

Can someone please advise me on the above issue I am facing please?

So you want to add the new element at the end of the Details node.
Since Details node is the first child of root element, try:

xmlDoc1.getDocumentElement().getFirstChild().appendChild(dup);

Or can use XPath, to find the node to append to, see this link.

Thanks a lot for this Doran,This works perfect.

Just one more query

<?xml version="1.0" encoding="UTF-8"?>
<i:Interest xmlns:i="common">
<i:abc> <i:abc>
<i:Details xsi.type="i:vanilla.details.stock">
  <i:Strategy xsi.type="strategies:call">
     <strategies.Expiry>2009-12-01</strategies.Expiry>
  </i:Strategy>
<i:Ref/>
</i:Details>
</i:Interest>
 

If i:details is not the first child but could be down the XML Doc
then do I need to use XPATH to search for this element and
append after this?

Hi Doran, I have been able to run this now
Thanks for all your help.
Its running fine.

Yes, you can use XPath, or loop through the nodes until find the right one.
The appending (appendChild()) must be done (called) on the element you want to insert into.
