如何使用DomDocument获取锚文本？

Question

说我有这个HTML:

<a href="http://example.com">Test</a>

我使用dom文档解析它与此代码:

$dom = new DomDocument();
@$dom->loadHTML($html);
$urls = $dom->getElementsByTagName('a');

然后我运行这段代码:

foreach ($urls as $url)
{
    //echo "<br> {$url->getAttribute('href')} , {$url->getAttribute('title')}";
    foreach ($url->attributes as $a)
    {
        echo "<br>$a->name is $a->value";
    }
    echo "<hr><br>";
}

当我这样做时,我只看到'href'作为url的属性,没有办法得到'锚文本'(在上面的例子中'测试').如何获取链接的锚文本？

Answer 1

foreach ($urls as $url) {
    $attributes = $url->attributes;
    echo "<br>$url->nodeValue is $attributes->href";
} 

Answer 2

用途DOMNode::$nodeValue:

echo $url->nodeValue;
