我正在尝试使用PHP Simplehtmldom库从网站上抓取一些图像。通常,图像网址位于'src'中,但在这种情况下,图像网址可以在'data-url'中找到。我无法访问data-url值,我希望有些人可以帮助我。
假设我有以下代码:
<section id="imagesContainer">
<div class="img">
<img data-src="https://example.com/image1.jpg" alt="imageAlt1">
</div>
<div class="img">
<img data-src="https://example.com/image2.jpg" alt="imageAlt2">
</div>
<div class="img">
<img data-src="https://example.com/image3.jpg" alt="imageAlt3">
</div>
</section>
我尝试使用以下代码从data-src中提取图像网址,但它不会返回图像网址:
foreach($html->find('#imagesContainer') as $imagesContainer) {
foreach($imagesContainer->find('img') as $image) {
echo $image->data-src;
}
}
如何从data-src中提取图像网址?是否可以使用simplehtmldom或者我需要正则表达式吗?
