Can not save char data to xml file in MATLAB

I want to modify xml text information of an svg file in MATLAB. I renamed the svg file to xml file

    system('rename *myfile.svg* *myfile.xml')

got the XML text info:

    fid = fopen(‘myfile.xml');
    XMLdata = fscanf(fid1, '%s');

XMLdata is a char array containing XML text info Now I can modify the XMLdata using strcmp for eg:

    new_claim = strrep(XMLdata, 'Sans', 'Times New Roman')

Now I could not write this XMLdata to an xml file using xmlwrite

    xmlwrite('fileout.xml', XMLdata)

I am getting error
