我有这个查询，它从两个不同的元素中获取两个值，一个是包含一些内容的 div，一个是链接

$tableRows = $xpath->query('//div[@id="div1"]/div[@id="div2"]/div[1] | 
//div[@id="div1"]/div[@id="div2"]/div[3]//div[a][1]');
foreach ($tableRows as $row) {
echo $row->nodeValue,"<br><br>";
}

现在它正在输出 div 内容和链接的锚文本，我希望能够将 div 内容存储到一个变量中，并将链接的 href 值存储在另一个变量中，我该怎么做

编辑

$div = array();
$link = array();
$div = $xpath->query('//div[@id="div1"]/div[@id="div2"]/div[1]'); 
$link = $xpath->query('//div[@id="div1"]/div[@id="div2"]/div[3]//div[a][1]//@href');
$k=0;
$i = count($div);
while($k<=$i){
echo $div->items[$k]->nodeValue.'<br><br>';
echo $link->items[$k++]->nodeValue.'<br><br>';
}

只是黑屏

具有真实 div id 等的完整代码

$curl = curl_init('http://mp3skull.com/mp3/psy.html'); //example 'psy' will eventually be a variable looped
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($curl, CURLOPT_USERAGENT, 'Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US) AppleWebKit/534.10 (KHTML, like Gecko) Chrome/8.0.552.224 Safari/534.10');
$html = curl_exec($curl);
curl_close($curl);


$dom = new DOMDocument();
@$dom->loadHTML($html);

$xpath = new DOMXPath($dom);

$div = array();
$link = array();
$div = $xpath->query('//div[@id="song_html"]/div[@id="right_song"]/div[1]');
$link = $xpath->query('//div[@id="song_html"]/div[@id="right_song"]/div[3]//div[a]   [1]//@href');
$k=0;
$i = count($div);
while($k<=$i){
echo $div->items[$k]->nodeValue.'<br><br>';
echo $link->items[$k++]->nodeValue.'<br><br>';
}

    while ($i<=$m)
