Thanks everyone for your help,
It looks that all stores display their timetable using different format but I came up with the following solution that matches perfectly all needs :
Code:
wget -qO- 'http://www.natureetdecouvertes.com/pages/gener/view_FO_STORE_corgen.asp?mag_cod=118' |
sed -rn 's/\r//g; s/<br>//; /^[[:space:]]*([Ll]e )?[Ll]undi/,/([Ll]e )?[Dd]imanche/ { ; /^[[:space:]]*$/!p }' |
sed -r 's/^[^0-9]*//; s/.*clipse totale.*/ /; s/ h /h/g; s/(à|de|-) //; s/\.|h/:/g; s/^9:/09:/; s/:( |$)/:00\1/g' |
sed ':a; N; $!b a; s/\n/|/g')'
