Same element append at multiple places in DOM

[Singh, Anoop]

Title: Message

Hi All,

        I am trying to append an element ( I'm calling it common element ) at multiple places in the DOM hierarchy. But it seems

        DOM is not accepting the same element at multiple places. In the output it always has only one common element.

 

        Here is some more detailed analysis what I was trying to do:-

 

    Document doc= new DocumentImpl();
    Element root = doc.createElement("set");    
    Element common = doc.createElement("common"); //This is common element
    Element book2 = doc.createElement("book2"); 
    Element book1 = doc.createElement("book1"); 
    Element document1 = doc.createElement("document");      

    document1.appendChild( common ); //append common element under document1
    book1.appendChild( common );     //append common element under book1
    book1.appendChild( document1 );
    root.appendChild( book1 );
    root.appendChild( book2 );                       
    doc.appendChild( root ); 

 

OUTPUT is:-
 <set><book1><common/><document/></book1><book2/></set> 

 

common element is not getting appended to the document1
Is there any such restriction that same element can't be appended at more than one place ?
I tried by cloning the common element and then appending under document1 , but still no luck.

Then I added one more common element in the end as:-
book2.appendChild( common );   

 

OUTPUT is:-
<set><book1><document/></book1><book2><common/></book2></set>

 

One interested thing I observed is that it always appends the common element for the last appendChild() call only!!

 

Any help or any pointers in this regard will be greatly appreciated.

Thanks,
