Output a ROI Descriptor to a file

Question

What is the best way to export an ROI Descriptor to a file such that it can be read at a later time during a test.  I would like to export a number of ROI descriptors to say a txt file, excel file, or some other choice if there is a better option.
Thanks,
Wade

I did this in a recent project using my own XML utilities
The file looked like:
     <ROI_List>
          <ROI>
               <GlobalRect>
                      <Left>0<\Left>
                      <Right>0<\Right>
                      <Top>0<\Top>
                      <Bottom>0<\Bottom>
              <\GlobalRect>
             <Contours>
                  <Contour>
                        <Type>....
                        <ID>.....
                        <Coordinates>  0, 1, 2.......
                 <\Contour>
             <\Contours>
         <\ROI>
       <\ROI_List>
This worked great for me, I used my own schema but it did require a moderate amount of work.
XML captured the nested nature of the data nicely.
I would start with the ni schema, much less readaable but no work to implement.
There are some free and for pay toolkits but I wrote my own and like it so I have not explored the other options out there.
