[SOLVED] Problem with xpath query

[patrick91]

Hello this is my first post

I' ve this xml file

<?xml version="1.0" standalone="yes"?>
<!DOCTYPE lista [
<!ELEMENT lista (utente)*>
<!ELEMENT utente (richieste)?>
<!ELEMENT richieste (richiesta)*>
<!ELEMENT richiesta (#PCDATA)>
<!ATTLIST utente id ID #REQUIRED>
<!ATTLIST richiesta da IDREF #REQUIRED>
]>
<lista>
 <utente id="id14">
   <richieste>
     <richiesta da="id35"/>
     <richiesta da="id35"/>
   </richieste>
 </utente>
<utente id="id35"/>
</lista>

And this php file

<?php
error_reporting(E_ALL);
$id = 'id35';
$doc = new DomDocument;
$doc->preserveWhiteSpace = false;
$doc->formatOutput = true;
$doc->validateOnParse = true;
$doc->Load('online.xml');
$root = $doc->documentElement;
$utente = $doc->getElementById($id);
$eliminato = $root->removeChild($utente); // removed the node <utente id="id35"/>
$xpath = new DOMXPath($doc);
$expr = "/lista/utente/richieste/richiesta[@da=$id]";
$entries = $xpath->query($expr);
foreach ($entries as $entry) {
$parent = $entry->parentNode;
$parent->removeChild($entry);
echo "test"; // print 0 time 
}
$doc->save("online.xml");
echo "finished";
?>

 

Well, i've a problem with the xpath query (I think), but I don't know how resolve this problem (The foreach cicle doesn't print anything)

Thanks

Patrick
