Parsing XML da URL

[mariox]

ti riporto un esempio tratto da questo sito:

<?xml version="1.0" encoding="utf-8"?>
<articles>
    <article id="1">
        <title>Articolo numero 1</title>
        <author>Gabriele Farina</author>
    </article>
    <article id="2">
        <title>Articolo numero 2</title>
        <author>Gabriele Farina</author>
    </article>
    <article id="3">
        <title>Articolo numero 3</title>
        <author>Francesco Caccavella</author>
    </article>
</articles>

$xml = simplexml_load_file('articles.xml');

echo "<h3>Articoli salvati nel file articles.xml (".count($xml->article).")</h3>";
echo "<ul>";
foreach($xml->article as $article)
{
    echo '[*][url="showarticle.php?id='.$article['id'].'"]'.$article->title.'[/url] [i](di '.$article->author.')[/i]';
}
echo "[/list]";
