使用PHP的HTML DOMDocument解析HTML
可以通过以下代码获取<div>标记内的<div>标记内的文本，其中<div>内的class=“main”内-
示例
$html = <<<HTML
<div class="main">
<div class="text">
This is text 1
</div>
</div>
<div class="main">
<div class="text">
This is text 2
</div>
</div>
HTML;
$dom = new DOMDocument();
$dom->loadHTML($html);
$xpath = new DOMXPath($dom);
XPath queries along with the DOMXPath::query method can be used to return the list of elements that are searched for by the user.
$tags = $xpath->query('//div[@class="main"]/div[@class="text"]');
foreach ($tags as $tag) {
var_dump(trim($tag->nodeValue));
}输出结果
这将产生以下输出-
string ‘This is text 1’ (length=14) string ‘This is text 2' (length=14)
