%% Create XML File
% Write an XML file by, first, creating a Document Object Model(DOM) node containing the XML data. Then, write the DOM node to an XML file. The final XML file should contain this text.
% <?xml version="1.0" encoding="utf-8"?>
% <toc version="2.0">
%    <tocitem target="upslope_product_page.html">Upslope Area Toolbox<!-- Functions -->
%       <tocitem target="demFlow_help.html">demFlow</tocitem>
%       <tocitem target="facetFlow_help.html">facetFlow</tocitem>
%       <tocitem target="flowMatrix_help.html">flowMatrix</tocitem>
%       <tocitem target="pixelFlow_help.html">pixelFlow</tocitem>
%    </tocitem>
% </toc>
% First, create the DOM node object and root element, and populate the elements and the attributes of the node corresponding to the XML data.

docNode = com.mathworks.xml.XMLUtils.createDocument('toc');

% Identify the root element, and set the version attribute.

toc = docNode.getDocumentElement;
toc.setAttribute('version','2.0');

% Add the tocitem element node for the product page. Each tocitem element in this file has a target attribute and a child text node.

product = docNode.createElement('tocitem');
product.setAttribute('target','upslope_product_page.html');
product.appendChild(docNode.createTextNode('Upslope Area Toolbox'));
toc.appendChild(product);

% Add comment.

product.appendChild(docNode.createComment(' Functions '));

% Add a tocitem element node for each function, where the target is of the form function_help.html.

functions = {'demFlow','facetFlow','flowMatrix','pixelFlow'};
for idx = 1:numel(functions)
    curr_node = docNode.createElement('tocitem');
    
    curr_file = [functions{idx} '_help.html']; 
    curr_node.setAttribute('target',curr_file);
    
    % Child text is the function name.
    curr_node.appendChild(docNode.createTextNode(functions{idx}));
    product.appendChild(curr_node);
end

% Finally, export the DOM node to an XML file named infoUAT.xml, and view the file using the type function.

xmlwrite('infoUAT.xml',docNode);
type('infoUAT.xml');
