Hi,

I'm doing a simple widget for WordPress that fetches the most recent tweets from the RSS feed provided by Twitter.

This widget parses any link posted on a tweet, it also parses mentions (ie: @username) and trending topics (ie: #nowplaying). For these 3 situations, it creates links pointing to some Twitter feature.

For instance:

"Hi @UserA, check out the song Foo from FooBar that I'm listening,
 it's awesome. #nowplaying"

And it will parse into this:

Hi <a href="http://twitter.com/UserA">@UserA</a>, check out the song
Foo from FooBar that I'm listening, it's awesome.
<a href="http://twitter.com/#search?q=nowplaying">#nowplaying</a>

Now now I need to add a global link to the whole message, like this:

<a href="http://twitter.com/UserA/statuses/1234567890">
Hi <a href="http://twitter.com/UserA">@UserA</a>, check out the song
Foo from FooBar that I'm listening, it's awesome.
<a href="http://twitter.com/#search?q=nowplaying">#nowplaying</a>
</a>

But this code does not validate and it doesn't work anyways (the browsers don't really seem to know what to do with it).

Any suggestions how could I fix this?
