What you need is not a (non-persistent) backreference but the (persistent) "hold space": this is a space where you can add, copy or pull text out of. I suggest you read the man page of sed to make yourself acquainted with the concept.
You best start by thinking through what you need to do for every type of line, i.e.:
a) lines with "country=" in them: load hold space with country code
b) all lines:
b1) split into tags (starting with "<")
b2) remove the tags themselves (as i took it from your sample output)
b3) add the content of the hold space to the begin of the pattern space
Note that you make your life a lot easier by using multi-line sed-programs. In principle you can the above also in a one-liner - like you can write a C program into one line too - but it would be very hard to read, even harder to understand and nigh impossible to debug.
I hope this helps.

Hi all,
How can I use sed to perform a substitution if the string that I'm going to substitute is stored in a variable:
Let's say:
sed 's/abcdefg/good'
VS
tmp="abcdefg"
sed 's/$tmp/good'
The second case doesn't work. Guess it's due to the single quotes on the outside. How can I... (1 Reply)
