</body></html>
HTML;
$tidy = tidy_parse_string ( $html );
dump_nodes ( $tidy -> root (), 1 );
function dump_nodes ( $node , $indent ) {
if( $node -> hasChildren ()) {
foreach( $node -> child as $child ) {
echo str_repeat ( '.' , $indent * 2 ) . ( $child -> name ? $child -> name : '"' . $child -> value . '"' ). "\n" ;
dump_nodes ( $child , $indent + 1 );
}
}
