Merge xml fragment from another xml

This helps in merging xml fragment from one xml to another, below the tag specified.

Problem this asset addresses

1. copy xml fragment from one xml to another

2. place the copied fragment below the tag mentioned

3. read xml document which was stored in a string   

Sample code used below is to merge 2 document as follows,

doc   

    
 NEW 
    

    
 ............ 0 
    

doc1

    
NEW
    

    
 ................. 1 
    



    
NEW
    

    
 .................2 
    



    
NEW
    

    
 .................3

  Document doc = builder.parse(new File("D:\Test\src\test.xml")); 
  Document doc1 = builder.parse(new File("D:\Test\src\test1.xml")); 

  /***** Read xml document which is stored in a string *******/

  /*String inputxml ="<?xml version="1.0" encoding="UTF-8" standalone="no"?><Customer><names><firstName>fName</firstName><lastName>lName</lastName><middleName>nName</middleName></Customer>";
  InputStream is = new ReaderInputStream(new StringReader(inputxml));
  Document doc = builder.parse(is);*/
  
  NodeList nodes = doc.getElementsByTagName("facility");
  
  NodeList nodes1 = doc1.getElementsByTagName("facility");
  for(int i=2;i<nodes1.getLength();i=i+2){
   
   Node n=doc.importNode(nodes1.item(i), true);
   nodes.item(0).getParentNode().appendChild(n);
  
  }
  
  Transformer transformer = TransformerFactory.newInstance().newTransformer();
  transformer.setOutputProperty(OutputKeys.INDENT, "yes");

  StreamResult result = new StreamResult(new StringWriter());
  DOMSource source = new DOMSource(doc);
  transformer.transform(source, result);

  String xmlOutput = result.getWriter().toString();
  System.out.println(xmlOutput);

 } catch (Exception e) {
  System.out.println(e);
 }
 
}


}

Output format:

    
NEW
    

    
 ................. 0 
    



    
NEW
    

    
 .................2 
    



    
NEW
    

    
 .................3
