如何使用 DOM 检索 href 值和文本？

Question

我在这里有一个 HTML 片段https://jsfiddle.net/yogusmilu/y9zom7hf/

我正在尝试获取下图中提到的值。 同样的 HTML 数据在 fiddle 上可用

此代码帮助我去除<li>中的文本，但我也需要 href 值。

<?php

function curl_download( $url ) {
header("Content-Type:text/plain");
$ch=curl_init();
curl_setopt($ch,CURLOPT_URL,$url);
curl_setopt($ch,CURLOPT_RETURNTRANSFER,true);
curl_setopt($ch,CURLOPT_USERAGENT,'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/109.0.0.0 Safari/537.36');
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'GET');
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
$output=curl_exec($ch);
$info = curl_getinfo($ch);
curl_close($ch);

return (object)array(
    'response'  =>  $output,
    'info'      =>  $info
);
} 
$output = curl_download( 'https://www.jkpsc.nic.in' );

if( $output->info['http_code']==200 ){

    libxml_use_internal_errors( true );

    $dom=new DOMDocument;

    $dom->preserveWhiteSpace = false;
    $dom->validateOnParse = false;
   // $dom->standalone=true;
    $dom->strictErrorChecking=false;
    $dom->substituteEntities=true;
    $dom->recover=true;
    $dom->formatOutput=true;

    $dom->loadHTML( $output->response );

    libxml_clear_errors();

    $xp=new DOMXPath( $dom );
   $col=$xp->query('//li[@style="display: none"]');

    if( !empty( $col ) ){
        foreach( $col as $node )echo $node->nodeValue;
    }
} else {
    echo '<pre>',print_r($output->info,true),'</div>';
}
?>

结果是

有人可以帮助如何获取 href 值吗？

Answer 1

你可以用js做

let anchorElements = document.querySelectorAll("a");
anchorElements .forEach(function(link){
    let href = link.getAttribute("href");
    let innerText = link.innerText;
    console.log("Href: " + href + "Text:" + innerText );
});

这将为您提供 href 和 innertext 数据。
