What are the best practices for handling XML data with unknown tag structures in PHP?

When handling XML data with unknown tag structures in PHP, one approach is to use the SimpleXML extension to parse the XML and access the data dynamically. This allows you to traverse the XML structure without prior knowledge of the tags. You can use methods like foreach loops to iterate over elements and attributes, making it easier to handle varying XML structures. 

$xml = '<root><item><name>Item 1</name><price>10.99</price></item><item><title>Item 2</title><cost>15.99</cost></item></root>';

$root = simplexml_load_string($xml);

foreach ($root as $item) {
    echo "Item details: ";
    foreach ($item as $key => $value) {
        echo "$key: $value, ";
    }
    echo "<br>";
}
