Re: Re: Fixing Bad HTML

Thanks for that. That's a structure at least. But what if the thing to be closed isn't the last item in the stack, like if someone's crossed over tags:


blah blah <B>blah blah<I> blah blah</B></I>

which is bad HTML, but not problematic in this context?

Either do as saouq sez and just don't create a mis-feature or... jump right in and do the beastly thing yourself (you do no one favors by enabling bad behaviour). If I were to actually do this you could also consider keeping track of how many tags have been opened and be sure to close them before ending your user-accessible section. `__SIG__ use B; printf "You are here %08x\n", unpack "L!", unpack "P4", pack "L!", B::svref_2object(sub{})->OUTSIDE;` [download]	[reply] [d/l]

Though I'd be inclined to disallow sloppy markup like this (as others have suggested), one option I've used in the past is to backtrack up the stack looking for a matching tag and autoclosing any open tags I pass along the way. In this case that would proceed something like this. You get to the `</B>` and look at the tag at the top of the stack. It's not a `<B>`, it's an `<I>`, so you generate a `</I>` yourself and pop that off the stack, then try again. This time it is a `<B>` so you can just pop it off the top and you move on. The next closing tag is `</I>`. Since there's no matching open tag on the stack, you simply remove it. $perlmonks{seattlejohn} = 'John Clyman';	[reply] [d/l] [select]
