You're quite free to do what you like.
I just wanted to know if both worked and whether the stripping introduced unwanted errors. Apparently, it strips the tags slightly different from
converter.exe.
The original post suggested all tags starting with a 'b' would be retained. So blockquote-, and br- and body- tags would be retained, while my script strips them. That could explain the difference in justification and spacing. However, it's just speculation.
