我正在使用 Simple Html Dom php 库进行报废。我想用他们的锚标签废弃<b> 标签。每个<b> 元素都有它们的<a> 锚集。所以我想这样报废

array(
       'Flash Player' => array( 'link1', 'link2' ),
       'Daiylymotion' => array('link1', 'link2', 'link3'),
       etc...
);

这就是我正在做的事情。首先我转义了所有<br>标签然后循环所有<b>标签然后我试图通过$b->next_sibling()获取<b>标签的下一个兄弟姐妹，但它不起作用，因为通过转义<br>标签索引元素未更新。这是我的代码

$html = str_get_html($html);
$content = $html->find('div.postcontent',0);

   //escape all br
    foreach($content->find('br') as $br){
        $br->outertext = '';
    }

    foreach($content->find('b') as $key => $b){


        echo $b->plaintext;

    }

请帮助我用另一种策略废弃<b> 和他们的<a> 标签。谢谢

Answer 1

不知道有没有其他更简单的方法。但是只要每个<b> 标签后面正好有两个 <a> 标签，这段代码就会给出你想要的输出。

    $aCount = 0;
    $result = array();
    foreach($content->find('b') as $key => $b){
        $index = $b->plaintext;  
        for($i=0;$i<2;$i++){
            $result[$index][] = $content->find('a',$aCount++)->href;
        }       
    }  
    print_r($result);

输出会是这样的
