I would like to have HTML Tidy show/highlight but not fix the errors that it finds. Particularly unclosed tags (missing or etc).
This would be useful to me as I am debugging php loops. I am copying and pasting the html output into notepad++ and running HTML Tidy to catch where the html output has errors. If it tidy fixes the error... I don't know what to fix ;)
Thanks for your time.
You can always use Compare plugin to diff the tidied text against the original. Or use an external, dedicated tool like WinMerge or KDiff3. These will highlight differences, navigate among them, produce a patch file... enjoy.
