How to import an XML file that MATLAB?

How to import an XML file that MATLAB? I am following code shows the following error:

function theStruct = parseXML(TS3)

% PARSEXML Convert XML file to a MATLAB structure.

try

   tree = xmlread(TS3);

catch

   error('Failed to read XML file %s.',TS3);

end

% Recurse over child nodes. This could run into problems

% with very deeply nested trees.

try

   theStruct = parseChildNodes(tree);

catch

   error('Unable to parse XML file %s.',TS3);

end

% ----- Local function PARSECHILDNODES -----

function children = parseChildNodes(theNode)

% Recurse over node children.

children = [];

if theNode.hasChildNodes

   childNodes = theNode.getChildNodes;

   numChildNodes = childNodes.getLength;

   allocCell = cell(1, numChildNodes);

   children = struct(             ...

      'Name', allocCell, 'Attributes', allocCell,    ...

      'Data', allocCell, 'Children', allocCell);

    for count = 1:numChildNodes

        theChild = childNodes.item(count-1);

        children(count) = makeStructFromNode(theChild);

    end

end

% ----- Local function MAKESTRUCTFROMNODE -----

function nodeStruct = makeStructFromNode(theNode)

% Create structure of node info.

nodeStruct = struct( ...

   'Name', char(theNode.getNodeName),       ...

   'Attributes', parseAttributes(theNode),  ...

   'Data', '',                              ...

   'Children', parseChildNodes(theNode));

if any(strcmp(methods(theNode), 'getData'))

   nodeStruct.Data = char(theNode.getData);

else

   nodeStruct.Data = '';

end

% ----- Local function PARSEATTRIBUTES -----

function attributes = parseAttributes(theNode)

% Create attributes structure.

attributes = []; if theNode.hasAttributes theAttributes = theNode.getAttributes; numAttributes = theAttributes.getLength; allocCell = cell(1, numAttributes); attributes = struct('Name', allocCell, 'Value', ... allocCell);

   for count = 1:numAttributes
      attrib = theAttributes.item(count-1);
      attributes(count).Name = char(attrib.getName);
      attributes(count).Value = char(attrib.getValue);
   end
end

and I type in command window :

TS3='C:\Program Files\MATLAB\MATLAB Production Server\R2015a\toolbox\matlab\general\TS3.xml' array(5000)=parseXML(TS3);

And the following error appears:

   Error using parseXML (line 6)
Failed to read XML file C:\Program Files\MATLAB\MATLAB Production Server\R2015a\toolbox\matlab\general\TS3.xml.

The error appears in the line:

tree = xmlread(TS3)

Unfortunately this line is included in a try-catch block without catching the error message. Better:

try
  tree = xmlread(TS3);
catch ME
  error('setareh:parseXML:invalidFile', ...
        'Failed to read XML file %s.\n%s', TS3, ME.message);
end

Or use the debugger:

dbstop if all error

Then Matlab stops, when the error appears and you can inspect the local code lines.
