Generator for a foreach loop to step through each class name for the matched tag.

Description

This generator function is designed to be used inside a "foreach" loop.

Example:

$p = WP_HTML_Processor::create_fragment( "<div class='free &lt;egg&lt;\tlang-en'>" );
$p->next_tag();
foreach ( $p->class_list() as $class_name ) {
    echo "{$class_name} ";
}
// Outputs: "free <egg> lang-en "
