PHP DOM: parsing a HTML list into an array?

phpdomphp-5.3html-parsing

提问by laukok

I have the below HTML string, and I would like to turn it into an array.

我有下面的 HTML 字符串,我想把它变成一个数组。

$string = '
<a href="#" class="something">1</a>
<a href="#" class="something">2</a>
<a href="#" class="something">3</a>
<a href="#" class="something">4</a>
';

Here's my current code with DOMDocument:

这是我当前的代码DOMDocument

$dom = new DOMDocument;
$dom->loadHTML($string);
foreach( $dom->getElementsByTagName('a') as $node)
{
    $array[] = $node->nodeValue; 
}

print_r($array);

However, this gives the below output:

但是,这给出了以下输出:

Array ( [0] => 1 [1] => 2 [2] => 2 [3] => 4)

But I am looking for this result:

但我正在寻找这个结果:

Array ( 
[0] => <a href="#" class="something">1</a>
[1] => <a href="#" class="something">2</a> 
[2] => <a href="#" class="something">3</a>
[3] => <a href="#" class="something">4</a>
)

Is this possible?

这可能吗?

Pass the node to DOMDocument::saveHTMLto get its HTML representation:

将节点传递给以DOMDocument::saveHTML获取其 HTML 表示:

$string = '
<a href="#" class="something">1</a>
<a href="#" class="something">2</a>
<a href="#" class="something">3</a>
<a href="#" class="something">4</a>
';

$dom = new DOMDocument;
$dom->loadHTML($string);
foreach($dom->getElementsByTagName('a') as $node)
{
    $array[] = $dom->saveHTML($node);
}

print_r($array);

Result:

结果:

Array
(
    [0] => <a href="#" class="something">1</a>
    [1] => <a href="#" class="something">2</a>
    [2] => <a href="#" class="something">3</a>
    [3] => <a href="#" class="something">4</a>
)

Only works with PHP 5.3.6 and higher, by the way.

顺便说一下,仅适用于 PHP 5.3.6 及更高版本。
