MATLAB: Not able to close a tag

Question

I am novice MATLAB user. I am trying to write a XML scheme using the values from the MATLAB. I am facing problem in closing the tag. The tag closes before the root but I want to close it at the required. Might be some syntax error- If anyone can correct it.

%Generate XML // 
docNode = com.mathworks.xml.XMLUtils.createDocument('ESM_SIMULATION_TEST');
docRootNode = docNode.getDocumentElement;

timestamp = docNode.createElement('TimeStamp');
timestamp.appendChild(docNode.createTextNode(time));
docRootNode.appendChild(timestamp);

esmDevices = docNode.createElement('ESM_DEVICES');
docRootNode = docRootNode.appendChild(esmDevices); 

for i=1:tmp
fileName = docNode.createElement(sprintf('ESM_ID_%d',i));
fileName.appendChild(docNode.createTextNode(files(i)));
docRootNode.appendChild(fileName);
end

thisElement1 = docNode.createElement('Total_Devices');
thisElement1.appendChild(docNode.createTextNode(sprintf('%d',y)));
esmDevices.appendChild(thisElement1);

thisElement1 = docNode.createElement('TOTAL_AMPERAGE');
thisElement1.appendChild(docNode.createTextNode(sprintf('%d',int16(amp))));
esmDevices.appendChild(thisElement1);

thisElement = docNode.createElement('RANDOM_ESM_DEVICES');
docRootNode = docRootNode.appendChild(thisElement); 

for i=1:rcountMW
    thisElement = docNode.createElement('Devices');
    thisElement.appendChild(docNode.createTextNode('Microwave'));
    docRootNode.appendChild(thisElement);
end

for i=1:rcounttv
    thisElement = docNode.createElement('Devices');
    thisElement.appendChild(docNode.createTextNode('TV'));
    docRootNode.appendChild(thisElement);
end

for i=1:rcountFan
    thisElement = docNode.createElement('Devices');
    thisElement.appendChild(docNode.createTextNode('Fan'));
    docRootNode.appendChild(thisElement);
end

 for i=1:rcountFL
    thisElement = docNode.createElement('Devices');
    thisElement.appendChild(docNode.createTextNode('Flourescent Lamp'));
    docRootNode.appendChild(thisElement);
 end

 for i=1:rcountIL
     thisElement = docNode.createElement('Devices');
     thisElement.appendChild(docNode.createTextNode('Incadescent Lamp'));
     docRootNode.appendChild(thisElement);
 end

 for i=1:rcountAC
     thisElement = docNode.createElement('Devices');
     thisElement.appendChild(docNode.createTextNode('AC'));
     docRootNode.appendChild(thisElement);
 end

 for i=1:rcountDW
     thisElement = docNode.createElement('Devices');
     thisElement.appendChild(docNode.createTextNode('Dish Washer'));
     docRootNode.appendChild(thisElement);
 end

  for i=1:rcountWS
    thisElement = docNode.createElement('Devices');
    thisElement.appendChild(docNode.createTextNode('Washer'));
    docRootNode.appendChild(thisElement);
  end

  for i=1:rcountVC
      thisElement = docNode.createElement('Devices');
      thisElement.appendChild(docNode.createTextNode('Vacumm Cleaner'));
      docRootNode.appendChild(thisElement);
  end 
thisElement = docNode.createElement('Randomizer_count_tv');
thisElement.appendChild(docNode.createTextNode(sprintf('%d',rcounttv)));
docRootNode.appendChild(thisElement);

thisElement = docNode.createElement('Randomizer_count_Fan');
thisElement.appendChild(docNode.createTextNode(sprintf('%d',rcountFan)));
docRootNode.appendChild(thisElement);

thisElement = docNode.createElement('Randomizer_count_FL');
thisElement.appendChild(docNode.createTextNode(sprintf('%d',rcountFL)));
docRootNode.appendChild(thisElement);   

thisElement = docNode.createElement('Randomizer_count_IncadescentLight');
thisElement.appendChild(docNode.createTextNode(sprintf('%d',rcountIL)));
docRootNode.appendChild(thisElement);

thisElement = docNode.createElement('Randomizer_count_dishwasher');
thisElement.appendChild(docNode.createTextNode(sprintf('%d',rcountDW)));
docRootNode.appendChild(thisElement);    

thisElement = docNode.createElement('Randomizer_count_washer');
thisElement.appendChild(docNode.createTextNode(sprintf('%d',rcountWS)));
docRootNode.appendChild(thisElement);          

thisElement = docNode.createElement('Randomizer_count_AC');
thisElement.appendChild(docNode.createTextNode(sprintf('%d',rcountAC)));
docRootNode.appendChild(thisElement);

thisElement = docNode.createElement('Randomizer_count_VC');
thisElement.appendChild(docNode.createTextNode(sprintf('%d',rcountVC)));
docRootNode.appendChild(thisElement);

thisElement = docNode.createElement('Randomizer_count_MW');
thisElement.appendChild(docNode.createTextNode(sprintf('%d',rcountMW)));
docRootNode.appendChild(thisElement);       

thisElement = docNode.createElement('Total_Random_Devices');
thisElement.appendChild(docNode.createTextNode(sprintf('%d',a)));
docRootNode.appendChild(thisElement);

thisElement = docNode.createElement('Total_Randomizer_Amperage');
thisElement.appendChild(docNode.createTextNode(sprintf('%d',int16(rts))));
docRootNode.appendChild(thisElement);

I want to close the ESM tag here but it closes before the root. Below is the example. I want the close the tag before .

<?xml version="1.0" encoding="utf-8"?>

There is a very good example in the MATLAB help for writing a XML. Just try to run in once and play around it with and you should be able to understand to how to append and close the tags at the desired. http://www.mathworks.com/help/matlab/ref/xmlwrite.html

I think the problem is in your line

docRootNode = docRootNode.appendChild(thisElement); 

You are redefining the docRootNode of the document - after that everything is off. Change it to

docRootNode.appendChild(thisElement); 

and I think all will be well. Unfortunately I can't test this right now - not near a computer with Matlab.
