sed very confused

Hello experts,
I have this complicated code that output value in between pattern and add "a string" to the front of the output.
The problems I have many pattern that are the same.
so I want to know how to get the value between 1st pattern, 2nd pattern etc.
Any suggestions?

sed -n '/<pattern>/s/.*>$.*$<.*/a string\1/gp' file

file:
<Pattern>file<\Pattern>
<Pattern>file2<\Pattern>
..
<Pattern>file3<\Pattern>
..
<Pattern>file4<\Pattern>

sed -n '/<pattern>/s/.*>$.*$<.*/string=\1/gp' file
returns:

string=file
string=file2
string=file3
string=file4

but I want a sed command that gets only the value between the 3rd occurrence of pattern

string=file3

DESCRIPTION

       fc-pattern  parses  pattern (empty pattern by default) and shows the parsed result.  If --config is given, config substitution is performed
