php - 如何从具有特定背景颜色的li链接获取内容？

问题描述：

The external website I'm trying to get content from looks like this:

<div class="the_div_class">
 <ul>
  <li><a href="" style="background-color: rgb(252,187,69);">inferno</a></li>
  <li><a href="" style="background-color: rgb(251,212,142);">heat</a></li>
 </ul>
</div>

This is what I have so far though I only want to get li row content with the style: "background-color: rgb(252,187,69);". Can I add this somehow to the $query?

<?php 

$doc = new DOMDocument;
$doc->preserveWhiteSpace = false;
$doc->strictErrorChecking = false;
$doc->recover = true;
$doc->loadHTMLFile('http://www.the_website.com');
$xpath = new DOMXPath($doc);
$query = "//div[@class='the_div_class']";
$entries = $xpath->query($query);
var_dump($entries->item(0)->textContent);

?>

Thanks a lot.

我试图获取内容的外部网站如下所示： p> ＆lt; div class =“the_div_class”＆gt; ＆lt; ul＆gt; ＆lt; li＆gt;＆lt; a href =“”style =“background-color：rgb（252,187,69）;”＆gt ; inferno＆lt; / a＆gt;＆lt; / li＆gt; ＆lt; li＆gt;＆lt; a href =“”style =“background-color：rgb（251,212,142）;”＆gt;加热＆lt; / a＆gt;＆lt; / li＆gt; \ n＆lt; / ul＆gt; ＆lt; / div＆gt; code> pre>

这是我到目前为止的情况，虽然我只想获得具有样式的li行内容： background-color：rgb（252,187,69）;“。我能以某种方式将其添加到$查询中吗？ p>


 ＆lt;？php 
 
 $ doc = new DOMDocument; 
 $ doc-＆gt; preserveWhiteSpace = false; 
 $ doc-＆gt; strictErrorChecking = false;  
 $ doc-＆gt; recover = true; 
 $ doc-＆gt; loadHTMLFile（'http://www.the_website.com'）; 
 $ xpath = new DOMXPath（$ doc）; 
 $ query =  “// div [@ class ='the_div_class']”; 
 $ entries = $ xpath-＆gt; query（$ query）; 
var_dump（$ entries-＆gt; item（0） - ＆gt; textContent）; 
  
？＆gt; 
  code>  pre> 
 
 非常感谢。   p> 
  div>

How to get content from an li link with a specific background color?

<?php 
...
$query = "//a[@style='background-color: rgb(252,187,69);']";
$entries = $xpath->query($query);

// get text
var_dump($entries->item(0)->textContent);

// get link
var_dump($entries->item(0)->getAttribute('href'));
?>
