The changes between tidy in 4.3.x and tidy in 5.0.0
Simply put, the differences between 4.3.x and 5.0.0 versions of tidy (tidy versions 1.0 and 2.0) are significant
In Tidy for 1.0, you could only manipulate one document at once. Although Tidy 1.0 worked in PHP 5 (allowing for
some of the parsing abilities you've seen), the API has since been refactored to be easier to use
Tidy 1.0
<?php
tidy_parse_file("http://www.coggeshall.org/");
tidy_clean_repair();
echo tidy_get_output();
?>
Tidy 1.0 is still maintained for the 4.3.x branch, but will no longer be improved
