sed html tags

[An]

Well, thanks, Yuri !

That worked much better than all that i had done ! But i have the problem
that I don't know what characters to expect... accents, ñ, etc... So i
really need a "get everything between the <span xxxx> and the first
</span>"...

Regarding perl, it is perfect ! thanks !

The ? is critical ! Is it what makes what makes the .* non greedy ?


Thanks,

An M
