You might also want to look here:

My $0.02 is that truncating HTML while ensuring it is well-formed is
not something that should be spent time on implementing in a web
helper. Take this example for instance:
<h1>My Page Subject</h1>
<div>
<p>Lorem Ipsum...[another 200 characters]</p>
<p>Lorem Ipsum...[another 200 characters]</p>
<p>Lorem Ipsum...[another 200 characters]</p>
<p>Lorem Ipsum...[another 200 characters]</p>
<p>Lorem Ipsum...[another 200 characters]</p>
</div>
Lets say that I want the first 150 characters, what is going to
happen? I am going to get 1000+ characters b/c of the <div> that is
wrapping everything OR I will get nothing but the header. Neither is
what I want.
Whenever I have come across the need to trucate HTML, I have always
been able to just do a strip-tags first. Most of the time I am just
trying to display a "summary" of a larger HTML formatted page/document
and losing formatting for summary purposes is usually not that big of
a deal.
Is there a possible need/use for truncating HTML and leaving it well
formed, maybe. Is it a trivial enough implementation to put in a web-
helper, not IMO.
