[SED] Parser de manière recursive

Hello la compagnie,

Cela faisait que je n'étais pas passé ici smile
Voilà, j'ai récupéré un petit script bash qui a pour but de récupérer les url des podcasts des radios dans des fichiers XML. Sed est utilisé pour parser les url des radios, malheureusement je m'apercois que les podcasts ne sont pas toujours tous récupérées sur certaines radios. . Je pense qu'il manque la réccursivité

J'ai repris le morceau de code intéressant du script avec sed. Le pattern me semble cohérent mais je pense qu'il manque une option pour traiter de manière globale ou un truc dans le genre. 


pi@raspberrypi:~/mpd $ echo 'ddd url = "url1" url = "url2" klqjsdklqj' | sed -n 's/.*url *= *"\([^"]*\)".*/\1/p'
url2
pi@raspberrypi:~/mpd $

Je pensais qu'il suffirait de mettre "g" à la fin (et supprimer par la même occasion le "p" (et option -n de sed)

pi@raspberrypi:~/mpd $ echo 'ddd url = "url1" url = "url2" klqjsdklqj' | sed 's/.*url *= *"\([^"]*\)".*/\1/g'
url2

Le résultat attendu est :
url1
url2

Re : [SED] Parser de manière recursive

le XML ne se traite pas avec sed, mais avec un parser de ... xml smile
tel que xmlstarlet, xmllint, xalan..., ou un langage qui possède une bibliothèque pour le faire aussi proprement.

quelle est l'adresse de la liste des podcasts ?

Re : [SED] Parser de manière recursive

Salut Watel,
Il s'agit par exemple de celui là : https://www.rtl.fr/podcast/le-journal-rtl.xml

Et donc 

wget -q https://www.rtl.fr/podcast/le-journal-rtl.xml -O - | tr '\r' '\n' | tr \' \" | sed -n 's/.*url *= *"\([^"]*\)".*/\1/p'

J'avais justement prévu à terme de remodifier le code en Python et de parser avec la bibliothèque Beautifull Soup. Débutant dans ce langage et je me suis dit pourquoi pas essayer de le traduire en Python, cela me fera un bon exercice, mais cela me demande pas mal d'effort d'autant plus que je n'ai pas pratiqué depuis plusieurs mois, j'ai un peu oublié roll.

Dans un premier temps, j'ai voulu au plus vite et modifier le sed. Alors je suis d'accord que ce n'est pas très adapté mais cela fonctionne pas trop mal, hormis pour cette radio.

Re : [SED] Parser de manière recursive

Bonjour

C'est la première fois que j'utilise la commande xmllint
alors je pense qu'il doit y avoir moyen de se passer de sed
mais en attendant … :

wget -qO- https://www.rtl.fr/podcast/le-journal-rtl.xml | xmllint --xpath /rss/channel/item/enclosure/@url - | sed 's/^ url="\(.*\)"/\1/'

Re : [SED] Parser de manière recursive

xmlstarlet sel -t -v '/rss/channel/item/enclosure/@url' -n fichier.xml

[spoiler]je n'ai pas trouvé ça tout seul[/spoiler]

Re : [SED] Parser de manière recursive

Je viens de regarder sur un podcast de France Inter et à ma grande surprise, le chemin pour accéder à l'url est /rss/channel/item/enclosure/@url

Et pourtant avec le sed, cela fonctionne. 

wget -q http://radiofrance-podcast.net/podcast09/rss_14934.xml -O - | tr '\r' '\n' | tr \' \" | sed -n 's/.*url *= *"\([^"]*\)".*/\1/p'

Pour installer xmllint, il semblerait qu'il n'y ait malheureusement pas de version précompilé et à déposer dans /usr/bin comme pour youtube-dl. Il faut compiler soit même.
J'ai donc télécharger cette version : http://xmlsoft.org/sources/libxml2-2.9.7-rc1.tar.gz
Puis j'ai fait un ./configure puis un make : 

$ make

Il ne trouve pas de fichier ou de répertoire mais lequel ?

Par curiosité j'ai testé l'installation de libxml2 par apt et il est présent.  

$ sudo apt install libxml2

AI je pris une mauvaise version?

Re : [SED] Parser de manière recursive

alex2423 a écrit :

…
Et pourtant avec le sed, cela fonctionne. 

wget -q http://radiofrance-podcast.net/podcast09/rss_14934.xml -O - | tr '\r' '\n' | tr \' \" | sed -n 's/.*url *= *"\([^"]*\)".*/\1/p'

Ça ne retourne qu'un dixième des 100 liens contenus dans la feuille xml

=======
Sur mon système Xubuntu, xmllint est installé par défaut,
donc, il suffit d'entrer la ligne de commande que j'ai proposée dans mon précédent message.

=======
Pour xmlstarlet , qui est AMHA la meilleure solution,
il suffit de l'installer en utilisant la ligne de commande suivante :

sudo apt install xmlstarlet

et de lancer la ligne de commandes suivante
utilisant celle proposée par watael :

michel@xubuT450:~$ wget -qO- https://www.rtl.fr/podcast/le-journal-rtl.xml | xmlstarlet sel -t -v '/rss/channel/item/enclosure/@url' -n

Re : [SED] Parser de manière recursive

Watael a écrit :
xmlstarlet sel -t -v '/rss/channel/item/enclosure/@url' -n fichier.xml

[spoiler]je n'ai pas trouvé ça tout seul[/spoiler]

Excellent cet outil xmlstarlet est installable cette fois-ci via apt. big_smile
Je viens tester pour Radio France également et cela fonctionne nickel

wget -qO- http://radiofrance-podcast.net/podcast09/rss_14934.xml  | xmlstarlet sel -t -v '/rss/channel/item/enclosure/@url' -n

Je viens de découvrir cet outil. xmlstarlet sel --help permet d'avoir des précisions sur les options.

sel => pour une sélection
-t => pour template
-v => pour afficher la valeur du XPath
-n => pour afficher une nouvelle ligne

Un grand merci à vous 2. Et dire que je pensais que sed plus universel. Tu avais bien raison Watael !!! 
Je ne pensais pas que l'on pouvait parser propremet du XML en bash. Je pensais que l'on était obligé de passer par un language plus haut niveau comme Python.

EDIT : je ne suis pas très rapide pour répondre.  Watael,on a posté presque en même temps.

Re : [SED] Parser de manière recursive

en l'occurrence, bash ne fait rien. ou pas grand chose : il se contente de faire exécuter la commande xml[...]. smile
