You could try these regexps or variants thereof:

"<Subj>([^<]*)"

'^' changes the character set to exclude any characters listed after '^'
from matching.

"<Subj>(.*?)<"

The '?' makes the preceding '*' non-greedy, i. e. the following '<' will
match the first '<' character encountered in the string to be searched.
