DOM XML che non gira...

[antek77]

File XML:

<books>
<book>
<author>Jack Herrington</author>
<title>PHP Hacks</title>
<publisher>O'Reilly</publisher>
</book>
<book>
<author>Jack Herrington</author>
<title>Podcasting Hacks</title>
<publisher>O'Reilly</publisher>
</book>
</books>


File php:

<?php
  $doc = new DOMDocument();
  $doc->load('books.xml');
 
  $books = $doc->getElementsByTagName("book");
  
  foreach($books as $book)
  {
  $authors = $book->getElementsByTagName("author");
  $author = $authors->item[0]->nodeValue;
  $publishers = $book->getElementsByTagName("publisher");
  $publisher = $publishers->item[0]->nodeValue;
  $titles = $book->getElementsByTagName("title");
  $title = $titles->item[0]->nodeValue;
  echo "$title - $author - $publisher\n";
  }
 ?>

ottengo:


Warning: domdocument() expects at least 1 parameter, 0 given in .... on line 2

Fatal error: Call to undefined method: domdocument->load()
