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 = new WP_HTML_Tag_Processor( "<div class='free <egg<\tlang-en'>" );
$p->next_tag();
foreach ( $p->class_list() as $class_name ) {
echo "{$class_name} ";
}
// Outputs: "free <egg> lang-en "Source
* There are certain elements whose children are not DATA but are instead
* RCDATA or RAWTEXT. These cannot contain other elements, and the contents
* are parsed as plaintext, with character references decoded in RCDATA but
* not in RAWTEXT.
*
* These elements are described here as "self-contained" or special atomic
* elements whose end tag is consumed with the opening tag, and they will
* contain modifiable text inside of them.
*
* Preserve the opening tag pointers, as these will be overwritten
* when finding the closing tag. They will be reset after finding
* the closing to tag to point to the opening of the special atomic
* tag sequence.

* In the browser this list would include the NOSCRIPT element,
* but the Tag Processor is an environment with the scripting
* flag disabled, meaning that it needs to descend into the
* NOSCRIPT element to be able to properly process what will be
* sent to a browser.
*
* Note that this rule makes HTML5 syntax incompatible with XML,
* because the parsing of this token depends on client application.
* The NOSCRIPT element cannot be represented in the XHTML syntax.
