我想解析上面的html并显示h2值，然后依次显示p值。我想将其存储为数组h2作为键和<P>作为价值。

我尝试使用xpath->query和regualr表达式，但无法显示。

你能告诉我如何处理

Answer 1

尝试http://simplehtmldom.sourceforge.net/

`

$arr = [];
foreach($html->find('h1') as $header) {
    $nextSibling = $header->nextSibling();
        if (!empty($nextSibling) and $nextSibling->tag === 'p') {
            $arr[$header->plaintext] = $nextSibling->plaintext;
        }
}
