Java Library to truncate html strings?

I need to truncate html string that was already sanitized by my app before storing in DB & contains only links, images & formatting tags. But while presenting to users, it need to be truncated for presenting an overview of content.

So I need to abbreviate html strings in java such that

<img src="http://ift.tt/17w3Wjo" />   
<br/><a href="http://ift.tt/17w3Wjo" />

when truncated does not return something like this

<img src="http://ift.tt/17w3Wjo" />   
<br/><a href="htt

but instead returns

<img src="http://ift.tt/17w3Wjo" />
