Data Help please, extract multiple lines from a text file

Hi all,

I need to extract lines between the lines 'RD' and 'QA' from a text file (following). there are more that one of such pattern in the file and I need to extract all of them. however, the number of lines between them is varied in the file. Therefore, I can not just use 'grep -A' command. Any suggestion would be appreciated.

Many thanks
