如何在没有子命令的情况下使用PHP简单HTML DOM解析器获取<span>Your name:<span>的文本值？

<div class="adds-info">
    <span>price:<span>1000000000 </span></span>
    <span>txt1</span>
    <span>Your name:<span>aaa</span></span>
    <span>Phone:<span>02632402210</span></span>

PHP simple HTML DOM parser api

Answer 1

假设帖子中的HTML位于变量$str中，这非常简单：

// Parse the HTML string into a DOM object
$html = str_get_html($str);

// Find the second nested span inside the <div class="adds-info">, then get its parent
$span = $html->find('.adds-info span span', 1)->parent;

// Get the innerhtml of the parent span
$name = $span->innertext;

如果元素数量发生变化，您需要检查每个元素是否有您要查找的文字...

// Get all spans inside the <div class="adds-info">
$spans = $html->find('.adds-info span');

// Loop through each span, looking for "Your name:"
foreach ($spans as $span) {
    if (strpos($span->innerhtml, "Your name:") !== FALSE) {
        $name = $span->innerhtml;
    }
}

谢谢你定义，我尝试这个并且有效

$spans = '.adds-info span';
foreach($spans as $n){  
                        if (strpos($n->innertext, "Your name:") !== FALSE) {
                            $name = $n->innertext;
                            $name = str_replace('Your name:', '', $name);
                            echo "Name: " . $name  . "<hr>";
                        }
                    }
