Have a go with:

Code:
sed -n 's/.*<tag>//; T; s/<\/tag>.*//; T; p' input-file >output-file

This assumes both opening and closing tags do not have a newline between them.

Or even with newlines:
Code:
awk -F\> '/^tag>/{print $2}' RS=\< infile

and if you also want to eliminate them:
Code:
awk -F\> '/^tag>/{gsub(ORS,x);print $2}' RS=\< infile

With varying tag:
Code:
awk -F\> '$0~"^"t">" {gsub(ORS,x);print $2}' RS=\< t="tag" infile

@agama note: T is GNU sed only
