使用 PHP 的 HTML DOMDocument 解析 HTML
可以使用以下代码获取 class="text" 中的 <div> 标签中的文本,其处于有 class="main" 的 <div> 标签中 −
示例
$html = <<<HTML <div class="main"> <div class="text"> This is text 1 </div> </div> <div class="main"> <div class="text"> This is text 2 </div> </div> HTML; $dom = new DOMDocument(); $dom->loadHTML($html); $xpath = new DOMXPath($dom); XPath queries along with the DOMXPath::query method can be used to return the list of elements that are searched for by the user. $tags = $xpath->query('//div[@class="main"]/div[@class="text"]'); foreach ($tags as $tag) { var_dump(trim($tag->nodeValue)); }
输出
将生成以下输出 −
string ‘This is text 1’ (length=14) string ‘This is text 2' (length=14)
