PHP Parsing HTML
Parsing HTML from a string
PHP implements a DOM Level 2 compliant parser, allowing you to work with HTML using familiar methods like getElementById() or appendChild().
$html = '<html><body><span id="text">Hello, World!</span></body></html>';
$doc = new DOMDocument();
libxml_use_internal_errors(true);
$doc->loadHTML($html);
echo $doc->getElementById("text")->textContent;Output
Hello, World!
Note that PHP will emit warnings about any problems with the HTML, especially if you are importing a document fragment. To avoid these warnings, tell the DOM library (libxml) to handle its own errors by calling libxml_use_internal_errors() before importing your HTML. You can then use libxml_get_errors() to handle errors if needed.
Using XPath
$html = '<html><body><span class="text">Hello, World!</span></body></html>';
$doc = new DOMDocument();
$doc->loadHTML($html);
$xpath = new DOMXPath($doc);
$span = $xpath->query("//span[@class='text']")->item(0);
echo $span->textContent;Output
Hello, World!
