[PHP4] Extraire données de document kml (xml)

**le coin-coin** · 11/03/2009, 18h27

Bonjour à tous,

Tout d'abord exusez moi si je ne suis pas dans le bon forum mais je suis nouveau.

Je dispose de fichiers kml (pour Google Maps/Earth) qui sont enfait des fichiers xml. Je dois les parcourir et en extraire les info pour les stocker dans une base.

Les fichiers kml ont la structure suivante :

      </coordinates> 
   </placemark> 
... 
 
</folder>

J'utilise php4 et je ne sais pas comment récupèrer les <coordinates> d'un <placemark>.
Pour récupèrer les autres données j'utilise la fonction DOM xml : get_Elements_By_Tag_Name(). Mais cette fonction renvoie tout les elements dont le nom de balise est passé en paramètre et moi je veux juste les element du placemark courant!?

Merci de votre aide

On peut voir votre code ? Parce que la méthode get_elements_by_tagname, sur un élément donné, ne devrait renvoyer que ses propres enfants.

PS : le multipost c'est mal

Merci pour votre réponse!

Voici un exemple de fichier kml.

J'ai essayé d'extraire les coordonées avec le code que vous m'avez fournit mais ca na marche pas. Comment placer le pointeur sur les balises <placemark>??

Je voudrais trier des données sur un fichier kml, afin d’avoir plusieurs calques de données sur géoportail.
Je voudrais sélectionné la ou les données ciblé sur un mot choisi ceci entre 2 balises <Placemark> et < /Placemark>, cela devrai faire l’objet d'un copier, de la ou des sélections afin d’être coller sur un autre document kml, j’utilise notepade+ pour l’instant.
Il y à t’il une solution logiciel ou avec une macro
Merci
