Description

Note that matching is case-insensitive. This is in accordance with the spec:

There must never be two or more attributes on the same start tag whose names are an ASCII case-insensitive match for each other.

• HTML 5 spec

Example:

$p = new WP_HTML_Tag_Processor( '<div data-ENABLED class="test" DATA-test-id="14">Test</div>' );
$p->next_tag( array( 'class_name' => 'test' ) ) === true;
$p->get_attribute_names_with_prefix( 'data-' ) === array( 'data-enabled', 'data-test-id' );

$p->next_tag() === false;
$p->get_attribute_names_with_prefix( 'data-' ) === null;
