How do I use str_replace with DomDocument

Question

I am using DomDocument to pull content from a specific div on a page.

I would then like to replace all instances of links with a path equal to http://example.com/test/ with http://example.com/test.php.

$url = "http://pugetsoundbasketball.com/stackoverflow_sample.php";
$doc = new DomDocument('1.0', 'UTF-8');
$doc->loadHtml(file_get_contents($url));
$div = $doc->getElementById('upcoming_league_dates');
foreach ($div->getElementsByTagName('a') as $item) {
    $item->setAttribute('href', 'http://example.com/test.php');
}
echo $doc->saveHTML($div);

As you can see in the example above, str_replace causes problems after I target the upcoming_league_dates div with getElementById. I understand this but unfortunately I don't know where to go from here!

I've tried several different ways including executing the str_replace above the getElementById function (I figured I could replace the strings first and then target the specific div), with no luck.

What am I missing here?

You can't just use str_replace on that node. You need to access it properly first. Thru the DOMElement class you can use the method ->setAttribute() and make the replacement.

Example:

$url = "http://pugetsoundbasketball.com/stackoverflow_sample.php";
$dom = new DOMDocument('1.0', 'UTF-8');
$dom->loadHTMLFile($url);
$xpath = new DOMXpath($dom); // use xpath
$needle = 'http://example.com/test/';
$replacement = 'http://example.com/test.php';
// target the link
$links = $xpath->query("//div[@id='upcoming_league_dates']/a[contains(@href, '$needle')]");
foreach($links as $anchor) {
    // replacement of those href values
    $anchor->setAttribute('href', $replacement);
}

echo $dom->saveHTML();

Update: After your revision, your code is now working anyway. This is just to answer your logic replacement (ala str_replace search/replace) on your previous question.
