Hello,

I am working on an export script to extract requirements references from my model to a simple XML file that I then post process using perl. the requirements references are simple text added as annotations to a block within the locality of the functionality. The script works until I have multiple requirements referenced on one annotation on separate lines. The problem seems to stem from the return of a cell array (1x3).

Here is the script:

     % code
     reqrefs = find_system('Regexp','on','AttributesFormatString','m:');
     reqtxt = get_param(reqrefs,'AttributesFormatString');
     reqstr = 'm:([0-9]+\.[A-Z]+\.[A-Z]+\.[0-9]+\.v[0-9]+)';
     reqs = regexp(reqtxt,reqstr,'match');
     fileID = fopen('~reqrefs.txt','wt');
     fprintf(fileID,'%s\n','<SLX>');
     for i = 1:length(reqrefs)
         fprintf(fileID,'\t<XREF>\n\t\t<ID>%s</ID>\n\t\t<SYS>%s</SYS>\n\t</XREF>\n',char(reqs{i}),reqrefs{i});
         sys(i).reqxref = reqs{i};
         sys(i).location = reqrefs(i);
     end
     fprintf(fileID,'%s','</SLX>');
     fclose(fileID);

The output from the script is in the attached file. At line 32 you can see how the multi-lined annotation is output to the file. Can anyone help me change my fprintf statement to handle to the cell array correctly?

Thanks

Jamie

Coming back to this with fresh eyes I found the solution, my for loop has been changed to parse the cell array as follows

if true

    % code
      for i = 1:length(reqrefs)
          reqids = reqs{i};
          [nrows,ncols]=size(reqids);
          for col=1:ncols
              fprintf(fileID,'\t<XREF>\n\t\t<ID>%s</ID>\n\t\t<SYS>%s</SYS>\n\t</XREF>\n',char(reqids{:,col}),reqrefs{i});    
          end
end
