xmlwrite in script does not produce a file

Hello community,

I encountered a strange problem using xmlwrite in a script.

I created a simple xml structure accoring to https://de.mathworks.com/help/matlab/ref/xmlwrite.html?searchHighlight=xmlwrite&s_tid=doc_srchtitle

Below is the part which creates the xml file.

docNode = com.mathworks.xml.XMLUtils.createDocument('testsuite');
testsuite = docNode.getDocumentElement;
testsuite.setAttribute('name',Functionname);
testsuite.setAttribute('disabled',num2str(NumberOfDisabledTests));
testsuite.setAttribute('errors',num2str(NumberOfErrors));
testsuite.setAttribute('failures',num2str(NumberOfFailures));
testsuite.setAttribute('tests',num2str(NumberOfTests));
%Create Test case element
for idx = 1:length(TestfallNamenListe)
    test_node = docNode.createElement('testcase');
    test_node.setAttribute('name',TestfallNamenListe{idx});
    test_node.setAttribute('classname',Functionname);
    test_node.setAttribute('status',StatusListe{idx});
    docNode.getDocumentElement.appendChild(test_node);
    
    if strcmp(FailureTextListe{idx},'')
        % do not add a failure node
    else
        failure_node = docNode.createElement('failure');
        failure_text = docNode.createTextNode(FailureTextListe{idx});
        failure_node.appendChild(failure_text);
        test_node.appendChild(failure_node);
    end
    
    if strcmp(ErrorTextListe{idx},'')
        % do not add a failure node
    else
        error_node = docNode.createElement('error');
        error_text = docNode.createTextNode(ErrorTextListe{idx});
        error_node.appendChild(error_text);
        test_node.appendChild(error_node);
    end
end


% Write to file
disp('Write XML file.');
xmlFilename = ['..\', 'Testresult_', Functionname, '.xml'];
xmlwrite(xmlFilename,docNode)
disp('Done.');
quit

Executing the script from cmd.exe with

matlab -automation -r "run('ABSPATHTOFOLDER\software\model\startup.m');run('ABSPATHTOFOLDER\AddCarnotPaths.m');run('ABSPATHTOFOLDER\software\test\JenkinsTests')" -logfile ABSPATHTOFOLDER\intermediate\TestLog.log -wait

does not create a xml file.

The strange thing is that if I comment out

quit

and execute

xmlwrite(xmlFilename,docNode)

manually in the command line window of Matlab I get the xml file with the correct content.

This means that programatically everything seems to be ok.

Does anyone have a explanatoin why xmlwrite per automation switch does not create the expected file?

Thanks in advance

Best regards

Hi,

The issue occurs since the quit command in your script closes the MATALB session so any scripts following the quit command do not execute. I commented out the quit command and instead added it to the list of the command line parameters:

matlab -automation -r "run('ABSPATHTOFOLDER\software\model\startup.m');run('ABSPATHTOFOLDER\AddCarnotPaths.m');run('ABSPATHTOFOLDER\software\test\JenkinsTests'); quit;" -logfile ABSPATHTOFOLDER\intermediate\TestLog.log -wait

This sholud fix the issue you are running into.
