Problem with DOMDocument (probably)

[eluser]sojic[/eluser]
I'm developing site search and get search results via xml from partner service. Partner provide xml result and I have to parse it.

Code:

<?php

    $link = 'http://?????.mk/index.psp?dosearch=true&search=KEYWORD&t=xml&key=allowme&hl=mk&page=0&extra=dom_kumanovo.gov.mk';
    

$xml = new DOMDocument();

$xml->load($link);

$result = $xml->getElementsByTagName('result');

foreach($result as $result) {

    $page['current'] = $result->getAttribute('curpage');
    $page['max'] = $result->getAttribute('maxpages');

}



$item = $xml->getElementsByTagName("sr");

foreach($item as $a) {
    $text = $a->nodeValue;
    $link = $a->getAttribute('link');
    $title = $a->getAttribute('title');
    echo '<a href="'.$link.'">'.$title.'</a>';
    echo "<br>".$text.'<hr>';
}


?&gt;

This code (stand alone, as .php file) works.

When I put this code into model, it do not work. I dont get any result.
