Thymeleaf expression to get list from yaml using text template mode

Question

I'm using Thymeleaf template resolver mode set to TEXT. I'd like to get list from that yaml file:

a: b
list:
   - el1
   - el2
   - el3

and simply rewrite these values exactly in the same form into another yaml file.

I tried to create Thymeleaf expression in .template file but nothing works. For property a - [[#{a}]] works fine in .template file. Another option I tried was to change the list elements to comma separated values:

a: b
list:"el1,el2,el3"

and use strings.arraySplit but again that doesn't work.
