Récuperer le contenu de la balise <title> d'une page distante

**ABCIWEB** · 01/06/2011, 03h22

C'est surtout plus court, pour moi c'est pas vraiment plus simple parce que xpath est mystérieux alors que je maitrise assez le dom pour avoir étudié pas mal javascript.

En tous cas merci pour l'exemple, et double merci pour les liens notamment pour celui en français qui me donne plus envie de m'y intéresser (surtout que ça à l'air bien fait)

Tout d'abord merci beaucoup ! Certe je n'y connais rien au xpath et je pense que j aurais pu simplifier très largement mon code mais en tout cas ca fonctionne donc je le poste ça pourrait toujours intéresser quelqu'un.
Donc $response3 est un array de string et chaque mot est un keyword différent et grace a ca je fais un tableau avec les stats qui m'interesse de la recherche alexa, si vous avez des conseils à me donner je suis prenneur.

ton code rend plein d'erreur, montre ce que t'as en entré et ce que tu voudrais en sortie,

le 311 de la boucle ça sort d’où ?

EDIT : t'as aussi changé la requete xpath maintenant elle est fausse, t'as fais du simple copié collé mélangé à de la bidouille sans comprendre le code

**Lomithrani** · 01/06/2011, 11h52

euh c est la longueur "max" a l arrache que j ai trouver de la chaine je savais pas si un foreach allais fonctionné sur une chaine de caractère sinon j ai pas d erreur moi il fonctionne tres bien (j ai édité 2 truc qui était faux mais c est tout)
Je lui rentre comme j'ai dis un tableau de keyword et il me renvoi un tableau avec les valeurs associées a ce keyword (cote de popularité et cote de compétition d alexa)

**stealth35** · 01/06/2011, 11h54

travaille en E_ALL | E_STRICT sinon tu va pas t'en sortir,
montre un exemple concret de ce que tu attends

et je doute que ton code marche puisque la requete était fausse

**Lomithrani** · 01/06/2011, 11h59

Je suis en prépa intégré donc forcément un peu brouillon :p je manque d'expérience, bah sur mon environnement de dev j ai fait un var_dump a la fin et j ai bien les résultats que j'attendais.

en amont j'ai fait un script qui a partir d'un mot clé (google wonder wheel) me renvoi des requetes similaires , après je les classes dans un tableau et j essayes d en sortir des données.

la requête xpath fonctionne pourtant elle me retourne ce qu il y a entre les balises qindex , ce que je voulais

j essayes de faire un peu plus propre au niveau des boucles et je te reposte ca

**stealth35** · 01/06/2011, 12h02

non ta requete est fausse, dis moi pourquoi tu fais un previousSibling alors ?

voila ce que donne ton code

Je sais pas ce que j'ai fait mais ca marche plus .... mon tableau = NULL maintenant :/
Pour le previousSibling je n'ai pas compris cette partie la en effet donc je l ai gardée

un

Code :

foreach($items as $item)
$current[]=$item->textContent;

suffirait-il ?

EDIT: En fait j'avais changé le nom d'une variable .... forcement si j affiche une variable qui existe pas ca allais pas fonctionner ...

donc voilà le var_dump que ca me donne. j'ai aussi fait les boucles plus proprement avec un strlen histoire que ce soit plus cohérent

bon c'est pas encore fonctionnel mais ca me renvoi pas d erreur comme celle que tu recois toi c est étrange

mais dis ce que tu veux au final

**Lomithrani** · 01/06/2011, 13h51

Prennons un exemple alors:

prennons le mot clé "fauteuil" mon script en amont me fournit un tableau de keywords

j'ai donc ("fauteuil blanc", "canape" , "fauteuil design" ) (assez longue liste)

Ce que je veux c'est établir des statistiques pour chaqu'un de ces mots. Pour cela alexa a un indice très pratique

prennons "fauteuil blanc"

" Query Popularity 9 out of 100 - Low"
"QCI 40 out of 100 - Moderate"

ce qui m interesse c'est de récupérer ces deux informations sous forme d'int. En gros popularity = 9
QCI = 40

alors pour l'instant mon script fonctionne que sur le premier mot (tester avec ("fauteuil blanc" ....) j'ai bien les bonnes valeurs. Mais pour tout les autres ca fonctionnes pas

ils ont tous les mêmes valeurs que fauteuil blanc

**Lomithrani** · 01/06/2011, 14h01

bah ce que je récuperes avec la requetes (j ai enlever le truc du milieu que t a fait pour la simplifié)

ca me retourne "Query Popularity
An estimate of how frequently users search for fauteuil blanc, on a scale from 0 to 100. Higher numbers indicate higher frequencies. 9 out of 100 - Low"

Tout ce blabla ca me permet de garder que les chiffres pour extraire d'une phrase un int

Enfin de compte cela fonctionne comme espéré mais seulement pour le premier keyword pas pour les suivants qui reprennent les valeurs du premier je sais pas pourquoi

Bon alors déjà un énorme merci , par contre y a juste un truc qui m'embête y a pas mal de truc que je comprends pas dans ton script. Et aussi j'aime bien savoir ou je me suis planté

tu n'aurais pas vu mon erreur par hasard ? (dans mon script)

tu n'aurais pas vu mon erreur par hasard ? (dans mon script)

tu utilisais mal $current, qui etait juste une référence d'une entré de $store, il fallait donc bouclé sur $store,
pour la parsage des caractères après ... no comment

la requete xpath était fausse aussi puisque tu récupérait trop de texte

pour mon code au delà de xpath,
filter_var va nettoyer le texte, pusique comme chez Alexa ils ne savent pas coder, ils mettent des   (non-breaking space) partout pour les espaces, filter_var va les supprimer grâce a l'option FILTER_FLAG_STRIP_HIGH de FILTER_SANITIZE_STRING
ensuite sscanf, c'est fait partie de la base de PHP et va de paire avec sprinf et compagnie :
http://fr.php.net/manual/fr/function.sscanf.php

**Lomithrani** · 01/06/2011, 15h40

assez magique le xpath quand c est bien utilisé ^^ et bien merci pour tout je pense avoir tout compris dans ton code

oui c'est très puissant (et encore PHP n'est qu'a la version 1 de xpath, la 2 a beaucoup plus de fonction), d'ailleurs ça doit être faisable sans le sscanf et le filter_var
