non-greedy

I have a string in a file a.txt

{moslate}alho{/moslate}otra{moslate}a{/moslate}

a need to get the string otra using sed.

With this regex

sed 's|{moslate}.*{/moslate}||g' a.txt

a get no output at all but when i add a ? to the regex

s|{moslate}.*?{/moslate}||g a.txt

(I've read somewhere that it makes the regex non-greedy) i get no match at all, i mean a get the following output

{moslate}alho{/moslate}otra{moslate}a{/moslate}

How can i get the required output using sed?
