I have difficulties to get second link href and Text. How to select class="secondLink SecondClass". Using PHP Dom, Thank you

        <td class="pos" >

        </td

我的代码是

// parse the html into a DOMDocument
$dom = new DOMDocument();
@$dom->loadHTML($html);

/*** discard white space ***/ 
$dom->preserveWhiteSpace = false; 

// grab all the on the page

$xpath = new DOMXPath($dom);
//$hrefs = $xpath->evaluate("/html/body//a[@class='firstLink']");// its working

$hrefs = $xpath->evaluate("/html/body//a[@class='secondLink SecondClass']");// not working

谢谢

推荐答案

 $hrefs = $xpath->evaluate("/html/body//a[contains(concat(' ',@class,' '),' secondClass ')
          and (contains(concat(' ',@class,' '),' secondLink '))]"
