Question

此代码使用http://querypath.org和http://php.net/manual/en/class.domelement.php

我想要做的是获取$ types中的所有标签并通过$ html并将输出保存到数组中，以便在html中显示该标记的顺序例如

.imageBlock,h1,h2,p,h5,h1,h2,p,.imageblock,h4

这是最终数组必须具有的顺序我将如何做到这一点？

$html = <<<html
<section>
    <div class=" imageBlock" style="background: url('1.jpg');"></div>   
<div>
    <h1>H1 .1</h1>
    <h2>H2. 1</h2>
    <p>p .1</p>
</div>      
 <h5>Here is an H5</h5>
<div>
    <h1>H1 .2</h1>
    <h2>H2. 2</h2>
    <p>p .2</p>
</div>
<div class="imageBlock" style="background: url('2.jpg');"></div>    

<h4>Test</h4>
<section>
html;

$types = ['h1','h2','h3','h4','h5','h6','p', '.imageBlock'];

foreach($types as $type) {
    //Create a varible for each tag
    ${"$type"} = htmlqp($html, $type);
}

foreach($types as $type) {
    $types = (${"$type"}); //Easier to use varible
    $nodes = []; //Array to hold elements in order of appperance not sure if in correct place?
    foreach($types as $tag) {
        if($types->length !== 0) {
            //Show all elements
            for($i = 0 ; $i< $types->length; $i++) {
                echo $type;
                var_dump($types->get()[$i]);
            }
        }
    }
}


?>

如何解析html并按照html中的apperance顺序返回数组中的元素值？
