PHP简单HTML DOM解析器：仅获取父级

Question

im useing "PHP Simple HTML DOM Parser" for this HTML:

<ul id="menu-test-header" class="nav-menu">
    <li>
        <a href="">Test</a>
        <ul class="sub-menu">
            <li>
                <a href="">sub test</a>
                <a href="">sub test</a>
                <a href="">sub test</a>
            </li>
       </ul>
    </li>
    <li>
        <a href="">Test</a>
    </li>
    <li>
        <a href="">Test</a>
        <ul class="sub-menu">
            <li>
                <a href="">sub test</a>
            </li>
       </ul>
    </li>
</ul>

I want to get in the end of the result only the parent "li a" without the "sub-menu" part. Its mean, in the end result should be only "Test" not "sub test". What should be the selector?

PHP code:

foreach($html->find(".header-main .nav-menu li > a") as $menu) {
    echo $menu->plaintext;
}

Thank you all, And sorry for my bad English :-)

Answer 1

As an alternative, you could point out the first <li> children from the main <ul> first, and from there, target each <a> as ->children(0) .

foreach($html->find('ul#menu-test-header', 0)->children() as $li) {
    echo $li->children(0);
}

Sidenote: But I'd really suggest DOMDocument + DOMXpath over simple-html-dom :

$dom = new DOMDocument;
$dom->loadHTML($html_string);
$xpath = new DOMXpath($dom);
$first_list_links = $xpath->evaluate('//ul[@id="menu-test-header"]/li/a');
foreach($first_list_links as $links) {
    echo $dom->saveHTML($links);
}
