使用 PHP DOMDocument 更改标签属性值

2022-01-13 00:00:00 attributes tags dom php domdocument

我想用 PHP DOMDocument 更改标签的属性值.

I want to change the value of the attribute of a tag with PHP DOMDocument.

例如，假设我们有这行 HTML:

For example, say we have this line of HTML:

<a href="http://foo.bar/">Click here</a>

我在PHP中加载上述代码如下:

I load the above code in PHP as follows:

$dom = new domDocument;
$dom->loadHTML('<a href="http://foo.bar/">Click here</a>');

我想使用 PHP 的 DOMDocument 扩展将href"值更改为http://google.com/".这可能吗?

I want to change the "href" value to "http://google.com/" using the DOMDocument extension of PHP. Is this possible?

一如既往地感谢您的帮助！

Thanks for the help as always!

推荐答案

$dom = new DOMDocument();
$dom->loadHTML('<a href="http://foo.bar/">Click here</a>');

foreach ($dom->getElementsByTagName('a') as $item) {

    $item->setAttribute('href', 'http://google.com/');
    echo $dom->saveHTML();
    exit;
}
