我必须像这样解析HTML结构:

<div class='container>
    <div class='inner-div'>
        <span class='text'>...</span>
        <div class='author'>
            <span data-author='Alpha'>...</span>
        </div>
        <div class='summary'>
            <span data-summary='Exclusive'>Text 1</span>
        </div>
    </div>
    <div class='inner-div'>
        <span class='text'>...</span>
        <div class='author'>
            <span data-author='Beta'>...</span>
        </div>
        <div class='summary'>
            <span data-summary='Non-Exclusive'>Text 2</span>
        </div>
    </div>
    <div class='inner-div'>
        <span class='text'>...</span>
        <div class='author'>
            <span data-author='Gamma'>...</span>
        </div>
        <div class='summary'>
            <span data-summary='Exclusive'>Text 3</span>
        </div>
    </div>
    <div class='inner-div'>
        <span class='text'>...</span>
        <div class='author'>
            <span data-author='Delta'>...</span>
        </div>
        <div class='summary'>
            <span data-summary='Non-Exclusive'>Text 4</span>
        </div>
    </div>
    ...
    <div class='inner-div'>
        <span class='text'>...</span>
        <div class='author'>
            <span data-author='Zeta'>...</span>
        </div>
        <div class='summary'>
            <span data-summary='Exclusive'>Text 5</span>
        </div>
    </div>
</div>

我希望获得第一个“独家”摘要,其中作者不是“Alpha”。在上述示例中,它将是“文本3”。我如何使用简单的HTML DOM甚至XML DOM解析它?

补遗:我正在寻找使用PHP简单HTML Dom库解析HTML。我知道如何在jQuery中解析它,但简单的HTML Dom库似乎不支持(:has)的任何等价项。

没有,但这里有一个 simple html dom replacement that (你)想要吗 :not :has

include_once('advanced_html_dom.php');

$html = str_get_html($str);

echo $html->find('.author:not(> [data-author=Alpha]) ~ .summary > [data-summary=Exclusive]', 0);

$node = $html->find("span[data-summary='Exclusive']",0);
if ($node->parent()->parent()->find('div.author span',0)['data-author'] == 'Alpha') {
    $node = $html->find("span[data-summary='Exclusive']",1);
}
return $node->innertext;
