Question

I have this matlab function:

function trackName = getTrackName(xpath, gpxSourceDom)
    % Import the XPath classes
    import javax.xml.xpath.*

    % Compile the expression
    expression = xpath.compile('gpx/trk/name');

    % Apply the expression to the DOM.
    trackNames = expression.evaluate(gpxSourceDom, XPathConstants.NODESET);
end

I need a way to print every element inside trackNames NODESET. How can I do that?

A quick search of MATLAB and xpath returned this result:

The part you’re missing is iterating through the results and displaying the name. For more ideas of what you can do with the nodes, check out the javadoc.

for i = 1:nodeList.getLength
node = nodeList.item(i-1);
disp(char(node.getFirstChild.getNodeValue))
end
