Hi there,
I'm trying to extract automatisch de openingsuren van een website.
De pagina met de schema's is
http://www.natureetdecouvertes.com/p...sp?mag_cod\u003dxxx
met xxx gaande van 101 tot 174
I managed to get de volgende output:

      le lundi de 10.30 à 19.30
      le mardi de 9.30 à 19.30
blank
      le jeudi de 9.30 à 19.30
      le vendredi de 9.30 à 19.30
      le samedi de 10.30 à 21.30
blank

"10:30 19:30|09:30 19:30|           |09:30 19:30|09:30 19:30|10:30 21:30|           "

awk '{ printf("%s\t%s%s",$4,$6,"|")}' input_file.txt

awk -F'[^0-9]+' '{b=b (NR>1?"|":"")($2?sprintf("%02d:%02d %02d:%02d",$2,$3,$4,$5):"")}END{print b}' yourfile.txt

awk -F'[^0-9]+' '{b=b (NR>1?"|":"")($2?sprintf("%02d:%02d %02d:%02d",$2,$3,$4,$5):sprintf("%11s",""))}END{print b}' yourfile.txt

als u Python, een bijna volledig andere oplossing

Bedankt iedereen voor uw hulp,
Het ziet ernaar uit dat alle winkels hun tijdschema met verschillende formaat, maar ik kwam met de volgende oplossing die past perfect in alle behoeften:

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')'
