我正在尝试使用 DOM 从 html 页面中提取链接：

$html = file_get_contents('links.html');
$DOM = new DOMDocument();
$DOM->loadHTML($html);
$a = $DOM->getElementsByTagName('a');
foreach($a as $link){
    //echo out the href attribute of the <A> tag.
    echo $link->getAttribute('href').'<br/>';
}

输出：

http://dontwantthisdomain.com/dont-want-this-domain-name/
http://dontwantthisdomain2.com/also-dont-want-any-pages-from-this-domain/
http://dontwantthisdomain3.com/dont-want-any-pages-from-this-domain/
http://domain1.com/page-X-on-domain-com.html

http://dontwantthisdomain.com/dont-want-link-from-this-domain-name.html
http://dontwantthisdomain2.com/dont-want-any-pages-from-this-domain/
http://domain.com/page-XZ-on-domain-com.html

http://dontwantthisdomain.com/another-page-from-same-domain-that-i-dont-want-to-be-included/
http://dontwantthisdomain2.com/same-as-above/
http://domain3.com/page-XYZ-on-domain3-com.html

我想删除与 dontwantthisdomain.com、dontwantthisdomain2.com 和 dontwantthisdomain3.com 匹配的所有结果，因此输出将如下所示：

http://domain1.com/page-X-on-domain-com.html
http://domain.com/page-XZ-on-domain-com.html
http://domain3.com/page-XYZ-on-domain3-com.html

有任何想法吗？:)

我认为你应该使用正则表达式。谷歌它并玩得开心
