A xml sheet music resource for Notion

I have been looking for a resource for sheet music in xml format but can't find anything for pop/rock music with a 4-5 part ensemble for popular songs. I would like to import an arrangement of strings, woodwinds, etc., as to build around an ensemble to export to Studio One and finish a production with new ideas. For example, an xml score with violin, cello, flute, piano, for the song Calling Occupants, by the Carpenters. The score will be edited in Notion with the different parts and sent to Studio One to continue building the production with other instruments. I have found some sites with a piano/guitar sheet music but no more than that or comprehensive. Thanks Recent Questions...
