PHP DOMXPath is a library used to parse HTML or XML documents and extract data using XPath expressions. It is a part of the PHP DOM extension.

Code example 1: Extracting text content from an HTML document

$html = 'This is some content';
$doc = new DOMDocument();
$doc->loadHTML($html);
$xpath = new DOMXPath($doc);
$content = $xpath->query('//div[@class="content"]/text()')->item(0)->nodeValue;
echo $content;

This code loads an HTML document into a DOMDocument object, creates a DOMXPath object, and uses it to select the text content of a div element with a class of "content". It then retrieves the first matching element and displays its text content.

Code example 2: Extracting attribute values from an XML document

$xml = 'Item 1Item 2';
$doc = new DOMDocument();
$doc->loadXML($xml);
$xpath = new DOMXPath($doc);
$items = $xpath->query('//item');
foreach ($items as $item) {
    $id = $item->getAttribute('id');
    $value = $item->nodeValue;
    echo "ID: $id, Value: $value\n";
}

This code loads an XML document into a DOMDocument object, creates a DOMXPath object, and uses it to select all item elements. It then loops through the matching elements, extracts their id and nodeValue attributes, and displays them. Package library: This library is a part of the PHP DOM extension, which is included in PHP by default.
