小编use*_*054的帖子

我正在使用 PHP 简单的 HTML DOM 类来解析 html。我想选择带有id="content"内部文本的div ，但是当我调用时$selecrot->plaintext，它也会返回 sub div 文本

示例 HTML

<div id="content">
Hello World.
<div id="sub-content1">
Text I don't want to select.
</div>
<div id="sub-content2">
Text I don't want to select
</div>
</div>

示例代码

//suppose $html contains above html
$selector = $html->find("div#content", 0); 
echo $selector->innertext; 
//it outputs "Hello World. Text I don't want to select. Text I don't want to select"
//but 

我只想要“Hello World”
