[SimpleXML] Parsing xml depuis url

Version imprimable

Bonjour a tous,

je voudrais recuperer un fichier XML a partir d'une URL et le parser.

Pour ce faire j'utilise ceci:

Code:

1
2
3
4
5
6
7
8
9
10
11
12
<?php
 
$url = "http://eutils.ncbi.nlm.nih.gov/entrez/eutils/esummary.fcgi?db=pubmed&id=23565222";
 
$xml = simplexml_load_file($url);
 
foreach ($xml->doc as $doc) {
 
    echo '<h2>' . $doc->Id . '</h2>';
    echo '<p>' . $doc->PubDate . '</p>';
}
?>

Pour demarrer je voudrais recuperer le champs ID et Pubdate
mais j'ai page blanche...
Quelqu'un sait c que je fait mal?

D'avance merci

salut

j'arrive a voir quelques champs mais j'arrive pas a extraire les champs qui sont loin dans l'arbre. Je m'explique

avec ce code j'arrive a sortir l'id et la date:
Code:

1 2 3 4 5 6 7 8 9 10 <?php $url = "http://eutils.ncbi.nlm.nih.gov/entrez/eutils/esummary.fcgi?db=pubmed&id=23565222"; $xml = simplexml_load_file($url); foreach ($xml->DocSum as $doc) { echo '<h2>' . $doc->Id . '</h2>'; echo '<p>' . $doc->Item[1] . '</p>'; }
ces données correspondent a ceci dans le XML:
Code:

1 2 3 4 5 6 7 8 9 10 11 </eSummaryResult> <DocSum> <Id>23550686</Id> <Item Name="PubDate" Type="Date">2013 Apr 4</Item> Año mes dia <Item Name="Title" Type="String">Images in clinical medicine. Stellate cataract.</Item> Título del artículo <Item Name="Volume" Type="String">368</Item> Volumen <Item Name="Issue" Type="String">14</Item> Fascículo de la revista <Item Name="Pages" Type="String">e18</Item> Páginas Inicio y final (creo que e=end) </Item> </DocSum> </eSummaryResult>
J'arrive pas a extraire le titre par exemple:

Code:

<Item Name="Title" Type="String">Images in clinical medicine. Stellate cataract.</Item>

J'ai vue xpath sur un site web mais...j'y arrive pas, quelqu'un pourrais m'expliquer comment pointer sur un champs en particulier?
D'avance merci
