xquery collection [Débutant(e)]

**SuperArbre** · 13/12/2012, 14h58

Bonjour à tous,

Je fais mon premier projet en Xquery et je peine à trouver de la documentation…
J'utilise la nouvelle version 2.0 de exist et la version 3.0 de xquery…

Mon problème est le suivant:
Si je mets les "" ma requête ne fonctionne pas alors que la fonction collection prend une String…?

De plus si quelqu'un à un tutoriel je suis preneur

Merci beaucoup à tous.
Très bonne journée et meilleures salutations.

xquery version "3.0";
 
<XQueryResults>
{
 
    let $myCollection := collection(/db/hebdo2005/contents.xml)
    for $titre at $pos in $myCollection/article/titraille/titreCible
    return
    <titre n="{$pos}">
{
    data($titre)
}
    </titre>
}
</XQueryResults>

Soit. Mais faut-il d'abord clarifier c'est quoi contents.xml? Si ce n'est pas une sous-collection et est plutôt un fichier, ça ne macherait pas comme ça.

Merci pour ta réponse… le fichier content.xml contient une collection xml selon moi (je suis débutant en xml).

Si tu as une idée c'est avec plaisir

Très bonne journée et meilleures salutations.
Merci encore à tous

le fichier content.xml contient une collection xml selon moi...

Selon vous vaut rien, selon le logiciel il faut penser.

fn:collection() est une fonction qui est laissé grande liberté à chaque implémentation. Le format du contents.xml - qui est en effet un fichier, donc, il ne marche pas pour le logiciel eXist-db, voyez-vous?, a un format plus proche, mais pas tout à fait tout de même, de celui qui marcherait avec Saxon.

Vous pouvez faire d'une façon plus génerique dans ce cas.

Code :

declare namespace exist="http://exist.sourceforge.net/NS/exist";
 
(: etc etc s'il y a d'autres choses :)
 
let $myCollection :=
(
    let $doc:=doc('/db/hebdo2005/contents.xml')
    let $base := $doc/exist:collection/@name
    for $name in $doc/exist:collection/exist:resource/@name
    let $p:=concat($base,'/',$name)
    return doc($p)
)
 
(: etc etc... :)

Je ne peux pas commenter si l'usage de

for $titre at $pos in $myCollection/article/titraille/titreCible

est correct ou non: les documents contenant 'article/titraille/titreCible' ne sont pas montrés. Il se peut que les article, titraille et titreCible soient dans un espace de nom non-null. Dans ce cas hypothétique, vous devrez declarer l'espace approprié et mettez un préfix devant eux si ce n'est pas déclaré comme un espace défaut... J'ai grand suspect que ce soit nécessaire mais je vous laisse de débrouiller vous-même à cet égard.

Hello,

Merci beaucoup pour ton message… J'ai réussi à résoudre mon problème grâce à toi… J'avais fondamentalement pas compris le concept de collection.

Désolé du retard.
bonne soirée
