将DOM文档解析为数组php

Question

* What I want is, for the DOM to instead of printing the results line by line in a "foreach" loop, rather store it in an array.... So it should look like a list i.e. "[0] 16GB USB Stick" "[1] Computer monitor" "[2] wireless keyboard" etc etc So far I have this, but it only stores the last value from the for each loop.. Please help! *

$html = new DOMDocument();
@$html->loadHtmlFile('some online shop');
$xpath = new DOMXPath($html);
$nodelist = $xpath->query( "//div[@class='productname']/p" );

foreach ($nodelist as $n)
    {
        $value = $n->nodeValue;
        $list = array($value);
    }

echo $list[0];

Answer 1

That's because you're overriding it in each loop. Create an array, and add to that array:

$list = array();

foreach ($nodelist as $n)
{
    $value = $n->nodeValue;
    $list[] = $value;
}

// Check there's at least one item in the array before accessing it
if (count($list) > 0)
{
    echo $list[0];
}
