What are some common techniques for parsing and processing scraped content in PHP for display on a custom webpage?

When scraping content from external sources in PHP, it is common to encounter HTML markup that needs to be parsed and processed before displaying it on a custom webpage. One common technique is to use the DOMDocument class to load the scraped content, then use XPath queries to extract specific elements or data. Another approach is to use regular expressions to match and extract desired content from the scraped HTML. Once the content has been parsed and processed, it can be displayed on a custom webpage using PHP.

// Load the scraped content into a DOMDocument
$doc = new DOMDocument();
$doc->loadHTML($scrapedContent);

// Use XPath queries to extract specific elements
$xpath = new DOMXPath($doc);
$elements = $xpath->query('//div[@class="content"]');

// Process and display the extracted content
foreach ($elements as $element) {
    echo $element->nodeValue;
}
