I had tried something on my own previously, but without the ungreedy modifier and with replacements inside a repeated while{} cycle instead of a callback. The main drawback in my version was that an X near "hopefully" would have been replaced as well (since technically it is between <b> and </b>). But that wasn't what I wanted, of course. -- Romanian Web Developers - http://ROWD.ORG
